"Trace elements" are minerals that exist in minute quantities necessary for the growth and development of cells. Exposure to excessive quantities is toxic, but without them our bodies would atrophy. They are the crystalline structures that support life. Over the past decade, Aranda\Lasch has focused obsessively on these structures as a form of both organization and expression for architecture. Their projects explore the interplay between rule-based systems and human ritual. In scale, this work lies somewhere between furniture and building, so that what is built, drawn, and projected gives human measure to procedural thinking. Published on the occasion of the studio's exhibition "Meeting the Clouds Halfway" at the Museum of Contemporary Art (MOCA) Tucson, this book is a collection of recent explorations into modularity, craft, pattern, rhythm, material, and memory. Trace Elements documents a wide-ranging and yet sharply focused body of work from an office dedicated both to intellectual exploration and the honing of a distinct design sensibility.

Flux Redux is a book about design experiments undertaken at the Zurich and Los Angeles-based firm agps Architecture over the course of three decades. The story it tells addresses the evolution of a body of work relative to the evolution of environmental discourse, reflecting also on the shifting relations between technology and sustainability in architecture. The nine case studies from agps Architecture's portfolio record changes in how architecture is thought about and how it is made. Around 500 illustrations in the book are supplemented with texts by Marc Angelil, one of the founders of agps, and Cary Siress, architect and professor at the Nanjing University's Graduate School of Architecture and Urban Planning. Further contributions are provided by Swiss structural engineer Ernst Hofmann and Margarete von Lupin, a Zurich-based scholar of design and media studies and lecturer at Zurich University of the Arts and University of Zurich. Additional texts by Rainer Hehl, architect and visiting professor at Technische Universitat Berlin and Yokohama National University, and Alvaro Siza, one of the most distinguished architects of our time, round out this inspiring volume that also offers observations on architects' never-ending task of trial and error to make each building a more sustainable agent of a larger environmental system.

Carlo Scarpa was a virtuoso of light, a master of detail, and a connoisseur of materials. Today he is known as a 20th-century master of architecture. To mark the first centenary of Scarpa's birth, all his works are presented here for the first time. The 250 illustrations cover all 58 of his structures, including the Castelvecchio Museum (Verona), the Olivetti showroom (Venice), and the Brion Tomb in San Vito d'Altivole (Treviso), as well as his important glass designs. The book includes essays by leading architects and architecture critics, offering an extensive overview of Scarpa's life as well as interpretations of his architecture. Known as the "Frank Lloyd Wright of Italy," Scarpa's decorative style has become a model for architects wishing to revive craft and luscious materials in the contemporary manner.

Nicholas Hawksmoor (1662-1736) is considered one of Britain's greatest architects. He was involved in the grandest architectural projects of his age and today is best known for his London churches - six idiosyncratic edifices of white Portland stone that remain standing today, proud and tall in the otherwise radically changed cityscape. Until comparatively recently, however, Hawksmoor was thought to be, at best, a second-rate talent: merely Sir Christopher Wren's slightly odd apprentice, or the practically minded assistant to Sir John Vanbrugh. This book brings to life the dramatic story of Hawksmoor's resurrection from the margins of history.Charting Hawksmoor's career and the decline of his reputation, Owen Hopkins offers fresh interpretations of many of his famous works - notably his three East End churches - and shows how over their history Hawksmoor's buildings have been ignored, abused, altered, recovered and celebrated. Hopkins also charts how, as Hawksmoor returned to prominenceduring the twentieth century, his work caught the eye of observers as diverse as T. S.Eliot, James Stirling, Robert Venturi and, most famously, Peter Ackroyd, whose novel Hawksmoor (1985) popularized 12 the mythical association of his work with the occult. Meanwhile, passionate campaigns were mounted to save and restore Hawksmoor's churches, reflecting the strange hold his architecture can have over observers. There is surely no other body of work in British architectural history with the same capacity to intrigue and inspire, perplex and provoke as Hawksmoor's has done for nearly three centuries.

Jewel Changi Airport documents the creation of a remarkable addition to one of the world's premier airports. The sinuous, faceted glass Jewel serves as Singapore's new gateway to the world, and redefines what an airport can be. Brimming with terraced plantings, lush valleys, floating bridges, art installations, shops, restaurants, and a central waterfall, Jewel is a new type of destination: part public garden and part shopping and entertainment complex. Through photos, drawings, ephemera, essays, and interviews, the book provides detailed insights on how the project came to be - from its bold vision and concept to the innovative engineering, environmental, and construction strategies employed to make it a reality.

Recipient of 2019 John Brinckerhoff Jackson Book Prize, Foundation for Landscape Studies 2021 On the Brinck Book Award Winner "Burle Marx created a new and modern grammar for international landscape design." -Lauro Cavalcanti, quoted in the New York Times "The real creator of the modern garden." -American Institute of Architects Presenting the first English translation of Burle Marx's "depositions," this volume highlights the environmental advocacy of a preeminent Brazilian landscape architect who advised and challenged the country's military dictatorship. Roberto Burle Marx (1909-1994) is internationally known as one of the preeminent modernist landscape architects. He designed renowned public landscapes in Brazil, beginning with small plazas in Recife in the 1930s and culminating with large public parks in the early 1960s, most significantly the Parque do Flamengo in Rio de Janeiro. Depositions explores a pivotal moment in Burle Marx's career-the years in which he served as a member of the Federal Cultural Council created by the military dictatorship in the mid-1960s. Despite the inherent conflict and risk in working with the military regime, Burle Marx boldly used his position to advocate for the protection of the unique Brazilian landscape, becoming a prophetic voice of caution against the regime's policies of rapid development and resource exploitation. Depositions presents the first English translation of eighteen environmental position pieces that Burle Marx wrote for the journal Cultura , a publication of the Brazilian Ministry of Education and Culture, from 1967 through 1973. Catherine Seavitt Nordenson introduces and contextualizes the depositions by analyzing their historical and political contexts, as well as by presenting pertinent examples of Burle Marx's earlier public projects, which enables a comprehensive reading of the texts. Addressing deforestation, the establishment of national parks, the place of commemorative sculpture, and the unique history of the Brazilian cultural landscape, Depositions offers new insight into Burle Marx's outstanding landscape oeuvre and elucidates his transition from prolific designer to prescient counselor.

Eliot Noyes (1910-77) was a remarkable figure in twentieth-century design. An architect who began his career working in the office of Walter Gropius and Marcel Breuer, he went on to become the first Director of the Industrial Design department at MoMA in the 1940s. He was personally responsible for the design of some notable twentieth-century classics, such as IBM's Selectric typewriter and Mobil Oil's service stations and petrol pumps. His own work includes architectural projects, such as the award-winning Noyes family residence in Connecticut. The author has had extended access to the Noyes' archive of personal as well as business projects, materials and letters, and he has carried out extended interviews with a great deal of Noyes' acquaintances and relations. His comprehensive and lively text is accompanied by archival and new colour photography, drawings, plans and a diverse range of documentary material, much of which is previously unpublished.

The borough of Queens has long been celebrated as the melting pot of America. It was the birthplace of North American religious freedom in the seventeenth century, hosted two World's Fairs in the twentieth, and is currently home to over a million foreign-born residents participating in the American experience. In 2013, Spanish-born artist and architect Rafael Herrin-Ferri began to paint a portrait of the "World's Borough"-not with images of its diverse population, or its celebrated international food scene, but with photographs of its highly idiosyncratic housing stock. While All the Queens Houses is mainly a photography book celebrating the broad range of housing styles in New York City's largest and most diverse county, it is also a not-so-subtle endorsement of a multicultural community that mixes global building traditions into the American vernacular, and by so doing breathes new life into its architecture and surrounding urban context. With an introductory essay by Joseph Heathcott.

This is the first full biography of two of Scotland's most eminent Architects, James Miller and John James Burnet. While born just three years apart into very different circumstances - Burnet was the son of a wealthy Glasgow architect and Miller a farmer's son - their careers and lives became intertwined as they competed for work and eventually the role of Scotland's leading architect. Born in 1857 and 1860 respectively, one inherited and the other established successful practices in Glasgow at the zenith of that city's wealth in the late 19th century. John James Burnet, who was educated at the Ecole des Beaux Arts in Paris, and led his profession in Glasgow in the latter years of the 19th and early years of the 20th centuries, produced many of the city's finest buildings. These include The Athenaeum on Buchanan Street; Charing Cross Mansions; numerous city-centre commercial buildings such as Waterloo Chambers and Atlantic Chambers and the Townhouses on University Avenue. After moving to London, his work included the extension of the British Museum, The Daily Telegraph Building on Fleet Street and Adelaide House by London Bridge. Burnet was knighted and awarded the RIBA's Gold Medal in 1923 and is recognized as one of Scotland's finest architects. James Miller is simply Scotland's most prolific architect. During his long career he designed The Empire Exhibition of 1901, Glasgow Royal Infirmary, Glasgow Central Station, Wemyss Bay Station, St Enoch's Underground Station, Turnberry Hotel, Peebles Hydro Hotel, Gleneagles Hotel, the interiors of the SS Lusitania and SS Aquitania, Hampden Park, Forteviot Model Village, the Institution of Civil Engineers in Westminster, numerous banks, commercial buildings and churches in Glasgow and beyond as well as schools, country houses, factories and town halls. Despite this extraordinary output and his considerable architectural contribution to Scotland's heritage, he has received relatively little acclaim, until now. This is a fascinating double biography, the story of Burnet and Miller's parallel lives and work, set against the background of the booming Empire's 'Second City'.

The first in-depth exploration of the award-winning King Abdulaziz Center for World Culture in Saudi Arabia, designed by Norwegian architects Snøhetta Ithra, also known as the King Abdulaziz Center for World Culture, in Dhahran, Saudi Arabia, is an unprecedented architectural achievement. Designed on a monumental scale by the Norwegian architectural firm Snøhetta, built by Saudi Aramco, and inaugurated by King Salman bin Abdulaziz in late 2017, Ithra has been listed in Time magazine as one of the world's top 100 places to visit and is the winner of Project of the Year and Best Innovative Project of the Year at the Construction Innovation Awards in 2019. This multi-purpose cultural institution, with its unusual geometric sculptures, is one of a kind in contemporary architecture. With stunning imagery and a holographic wrap-around case, the book offers an in-depth, behind-the-scenes look at the inspiration for Ithra, from the competition process and selection of the architect to its complex construction and reveals the story behind this striking architectural gem, from its inception to its realization.

Architect Albert Frey (1903-1998) saw a modernist utopia in the desert. Born in Zurich, he studied in Europe with Le Corbusier before moving to the United States in 1930, convinced it was the land of architectural opportunity. On a visit to Palm Springs, he fell under the desert spell. It was here, amid the arid and empty landscape, that he could truly envisage a perfect modern future. Like fellow Californian luminary, John Lautner, Frey would spend the rest of his career nurturing the consonance of architecture and nature: studying the fall of sunlight and rain, and merging aluminum, steel, and glass with the boulders and sands of the West Coast wilds. His vision centered in particular on Palm Springs, capitalizing on the city's postwar population boom to create a bastion of the sleek, leisurely modernism that defines midcentury California. In this dependable architect introduction, we follow Frey's long and prestigious career from his European beginnings through to the apogee of his Californian practice, taking in his notes on De Stijl, Le Corbusier, and Bauhaus, and exploring the stylistic, material, and geographic makings of his unique "desert modernism." About the series Born back in 1985, the Basic Art Series has evolved into the best-selling art book collection ever published. Each book in TASCHEN's Basic Architecture series features: an introduction to the life and work of the architect the major works in chronological order information about the clients, architectural preconditions as well as construction problems and resolutions a list of all the selected works and a map indicating the locations of the best and most famous buildings approximately 120 illustrations (photographs, sketches, drafts, and plans)

Hillier: Selected Works presents the design work of the husband-and-wife team of J. Robert and Barbara A. Hillier during the last 25 years coupled with a brief graphic retrospective of the Hillier practice of architecture over 57 years of operation. Despite taking unconventional paths to architecture, both Hilliers enjoyed exhilarating careers growing the firm to 500 people and executing nearly 4,000 projects in 27 U.S. States and 34 Foreign Countries. The quality of the firm’s work has been honoured by over 350 design awards. The selected projects in this monograph are driven by strictly disciplined programming and then conceived by bringing into balance all the forces at work on a project: culture, climate, site, economics, market, and even politics. The resultant architecture is distinctive of its time, its place, and its client, rather than of a particular language or style. In 2008, Hillier Architecture, then one of the largest firms in the USA, merged with a foreign firm to create the 3rd largest architectural firm worldwide. Studio Hillier, the firm’s current iteration, was formed in 2012. More recently, NJIT’s College of Architecture and Design was renamed the J. Robert and Barbara A. Hillier College of Architecture and Design, celebrating the Hilliers’ commitment to providing more equitable access to design education.

A stunning celebration of the architect's residential masterpieces Louis Kahn (1901-1974), one of the most important architects of the postwar period, is widely admired for his great monumental works, including the Kimbell Art Museum, the Salk Institute, and the National Assembly Complex in Bangladesh. However, the importance of his houses has been largely overlooked. This beautiful book is the first to look at Kahn's nine major private houses. Beginning with his earliest encounters with Modernism in the late 1920s and continuing through his iconic work of the 1960s and 1970s, the authors trace the evolution of the architect's thinking, which began and matured through his design of houses and their interiors, a process inspired by his interactions with clients and his admiration for vernacular building traditions. Richly illustrated with new and period photographs and original drawings, as well as previously unpublished materials from personal interviews, archives, and Kahn's own writings, The Houses of Louis Kahn shows how his ideas about domestic spaces challenged conventions, much like his major public commissions, and were developed into one of the most remarkable expressions of the American house.

In summer 2017, celebrated Swiss architect Peter Zumthor curated the exhibition Dear to Me at the Kunsthaus Bregenz, marking the 20th anniversary of one of his most famous designs. Part of the program were conversations with philosophers, curators, historians, composers, writers, photographers, collectors, and craftsmen that Zumthor had invited to contribute to the exhibition. His dialogues with them offer insights into the thoughts and practice of fascinating personalities. Together with his counterparts, he explores artistic preferences and practices, reasonings, as well as practical knowledge from artisanal experience. Always charming and affectionate, he follows-up persistently, and takes his guests with gentle determination on mutual intellectual strolls. The equally serious and serene conversations with Anita Albus, Aleida Assmann, Marcel Beyer, Helene Binet, Hannes Boehringer, Renate Breuss, Claudia Comte, Bice Curiger, Esther Kinsky, Ralf Konersmann, Walter Lietha, Olga Neuwirth, Rebecca Saunders, Karl Schloegel, Martin Seel, Ruedi Walli, and Wim Wenders are collected in 17 booklets held together in an exquisitely manufactured box. An 18th complementary booklet documents the Dear to Me exhibition in Bregenz through concise texts, images, drawings and plans.

Documents the projects of The Scarcity and Creativity Studio and shows how this work has developed a unique methodology for practicing and teaching architecture Aimed at students, teachers and professionals who are exploring the possibilities of design-build, the 16 built projects are fully documented in text, drawings and photos Projects are based in Norway, Chile, Ecuador, Kenya, China, Argentina and Lebanon.

Taking an interdisciplinary approach, weaving together art, philosophy, history, and literature, this book investigates the landscapes and buildings of Swedish architect Erik Gunnar Asplund. Through critical essays and beautiful illustrations focusing on four projects, the Woodland Cemetery, the Stockholm Public Library, the Stockholm Exhibition and Asplund's own house at Stennas, it addresses the topic of buildings accompanied by landscapes. It proposes that themes related to landscape are central to Asplund's distinctive work, with these particular sites forming a collection that documents an evolution in his design thinking from 1915 to 1940. The architect himself wrote comparatively little about his design intentions. However, through close reading and analysis of the selected projects as landscapes with architecture, author Malcolm Woollen argues that reflections of the history of Swedish landscape architecture and the intellectual climate in the late nineteenth and early twentieth centuries are evident in his work and help to explain the architect's intentions. This book is a must-have for academics, advanced students and researchers in landscape architecture and design who are interested in Nordic Classicism and the works of Erik Gunnar Asplund.

Spanish visionary Santiago Calatrava is renowned around the world as an architect, structural engineer, sculptor, and artist. Famed for bridges as much as buildings, he has made his name with neofuturistic structures that combine deft engineering solutions with dramatic visual impact. From the Athens 2004 Olympic sports complex and the Museum of Tomorrow to the Peace Bridge in Calgary, Alamillo Bridge in Seville, and the Mujer Bridge in Buenos Aires, Calatrava's creations show particular interest in the meeting point of movement and balance. With influences ranging from NASA space design to da Vinci's nature studies, the structures dazzle with a sense of lightness, agility, and aerodynamism, but always with a graceful poise amid their particular surroundings. This compact introduction explores Calatrava's unique aesthetic with key projects from his career, from early breakthroughs to his most recent work. Through buildings of culture, science, faith, and across his many famous bridges, we explore his integration of organic forms and human movements, and a uniquely fluid futurism, soaring towards tomorrow. About the series Born back in 1985, the Basic Art Series has evolved into the best-selling art book collection ever published.

Architecture, as a discipline and a profession, is facing several crises, which, as yet, it has by no means successfully overcome. The basic hypothesis of the Cosmowomen project is that fully incorporating women into the professional and academic field of architecture would generate new places for thought and attention on the part of professionals or consolidate and expand those that exist, while also intensifying the relationships between those ‘places of thought’, producing a kind of constellation. The exhibition incorporates the work of 65 women architects who have taken the master’s degree programme at the Bartlett School of Architecture in the past ten years, showing a total of 71 projects and including 283 images. The architects are of more than 20 different nationalities and have been tutored by 22 tutors, 50% of them women, who also come from a wide variety of backgrounds in cultural terms and professional experience. The exhibition catalogue includes texts by 20 women architects or professionals in related fields, all with outstanding academic records. Architects: Ana Alonso, Anna Andronova, Christia Angelidou, Felicity Barbur, Justine Bell, Paddi Alice Benson, Christine Bjerke, Romina Canna, Emma Louise Carter, Nicola Chan, Doville Ciapaite, Freya Cobbin, Charlotte Cole, Emma Colthurst, Malina Dabrowska, Naomi De Barr, Emily Doll, Sarah Earney, Sara Firth, Karen A.

Empress of Fashion is an intimate and surprising look at an icon who made a lasting mark on the world of couture.

Reflecting the historic first European seismic code, this professional book focuses on seismic design, assessment and retrofitting of concrete buildings, with thorough reference to, and application of, EN-Eurocode 8. Following the publication of EN-Eurocode 8 in 2004-05, 30 countries are now introducing this European standard for seismic design, for application in parallel with existing national standards (till March 2010) and exclusively after that. Eurocode 8 is also expected to influence standards in countries outside Europe, or at the least, to be applied there for important facilities. Owing to the increasing awareness of the threat posed by existing buildings substandard and deficient buildings and the lack of national or international standards for assessment and retrofitting, its impact in that field is expected to be major.

Written by the lead person in the development of the EN-Eurocode 8, the present handbook explains the principles and rationale of seismic design according to modern codes and provides thorough guidance for the conceptual seismic design of concrete buildings and their foundations. It examines the experimental behaviour of concrete members under cyclic loading and modelling for design and analysis purposes; it develops the essentials of linear or nonlinear seismic analysis for the purposes of design, assessment and retrofitting (especially using Eurocode 8); and gives detailed guidance for modelling concrete buildings at the member and at the system level. Moreover, readers gain access to overviews of provisions of Eurocode 8, plus an understanding for them on the basis of the simple models of the element behaviour presented in the book.

Also examined are the modern trends in performance- and displacement-based seismic assessment of existing buildings, comparing the relevant provisions of Eurocode 8 with those of new US prestandards, and details of the most common and popular seismic retrofitting techniques for concrete buildings and guidance for retrofitting strategies at the system level. Comprehensive walk-through examples of detailed design elucidate the application of Eurocode 8 to common situations in practical design. Examples and case studies of seismic assessment and retrofitting of a few real buildings are also presented.

From the reviews
"This is a massive book that has no equal in the published literature, as far as the reviewer knows. It is dense and comprehensive and leaves nothing to chance. It is certainly taxing on the reader and the potential user, but without it, use of Eurocode 8 will be that much more difficult. In short, this is a must-read book for researchers and practitioners in Europe, and of use to readers outside of Europe too. This book will remain an indispensable backup to Eurocode 8 and its existing Designers Guide to EN 1998-1 and EN 1998-5 (published in 2005), for many years to come. Congratulations to the author for a very well planned scope and contents, and for a flawless execution of the plan." AMR S. ELNASHAI

"The book is an impressive source of information to understand the response of reinforced concrete buildings under seismic loads with the ultimate goal of presenting and explaining the state of the art of seismic design. Underlying the contents of the book is the in-depth knowledge of the author in this field and in particular his extremely important contribution to the development of the European Design Standard EN 1998 - Eurocode 8: Design of structures for earthquake resistance. However, although Eurocode 8 is at the core of the book, many comparisons are made to other design practices, namely from the US and from Japan, thus enriching the contents and interest of the book." EDUARDO C. CARVALHO"

In 2011, Zurich-based architect Fawad Kazi, together with the KSSG-OKS planning consortium, won the competition for the rebuilding and extension of St Gallen's cantonal hospital (KSSG) and the new regional children's hospital for eastern Switzerland (OKS). By 2028, this huge undertaking will have transformed the whole area they are built in. This building monograph, laid out in five elegant volumes, documents in much detail the ambitious project, which is a significant trailblazer in the area of hospital design and urban development. This second volume is devoted to KSSG's Haus 10, situated at the northern end of the site. Connected to the hospital's main building by means of an ingenious passage, it serves to treat walk-in patients. Its flexible structure allows adaptions to suit also future needs of KSSG. The interior design is based on materials and features intended also for the other new buildings still to come. Text in English and German.

This book focuses on Kay Fisker (1893-1965)’s housing estates in Copenhagen. A leading exponent of Danish Functionalism, Fisker was influenced by Louis Sullivan, and had a strong belief in continuity, putting modernism in perspective and identifying precedents. He built many large-scale housing schemes, mostly for non-profit workers' housing associations, and developed innovative and beautifully considered high-density, low-rise block schemes, which have proven useful and influential to the growing number of contemporary architects who have examined his designs. Beautifully illustrated with photographs and architectural drawings, this book documents and critically analyses three of Kay Fisker's seminal housing projects in Copenhagen: Hornbaekhus (1923); Vestersohus (1935-39); and Dronningegarden (1943-58). These projects reflect how Fisker's work contains valuable lessons for contemporary architects in economy, precision and generosity in housing design. Essays by Martin Søberg, Poul Sverrild and Job Floris set Fisker’s work within their historical, social and architectural context. In the final section, architects from three leading contemporary practices – Clancy Moore, Monadnock and Tony Fretton - discuss how Kay Fisker has influenced their own approaches and work.
