Investigations presents a selection of the firm s projects, identifying a specific architectural element, material, or design process to reveal the unique character of the built results. Projects include the Los Angeles Museum of the Holocaust of sculpted concrete that enables the building to be located predominantly underneath a park; the folded surfaces of the Skyline Residence perched atop the Hollywood Hills; and Apertures, a mid-rise of hospitality and commercial uses in Mexico City for which a seismically-sound breeze-block system was developed. Each project is illustrated with photographs, drawings, and diagrams, and insightful essays speak to the firm s development over the years, including its experiments in design and construction.
