The city of Giza was a theoretical study for a high-density city, amidst the existing ancient pyramids, which could accommodate the resettlement of 250,000 Palestinian refugees. Giza illustrated a number of concepts which Moshe Safdie had been exploring prior to Habitat '67 such as workable high-density environments, three-dimensional reorganization of urban land uses, the organization of individual dwellings as spatial groupings, the hierarchical organization of transportation networks, and the utilization of mass-production construction techniques.

Columbus Center, a winning proposal for the redevelopment of the New York Coliseum site, is situated on four acres at Columbus Circle, adjacent to Central Park. The project incorporates offices, residences, a hotel, a retail center, and a cinema complex. The offices include the headquarters of Salomon Brothers and a sophisticated trading center.

The organization of the complex and its network of public spaces are designed to reinforce the civic image of Columbus Circle and to enhance the street's public life. Set back in a V-shape, two towers surround a 190-foot garden atrium. The towers' separation highlights the central axis of 59th Street and admits a generous amount of light into each floor. The two towers are structurally independent but share horizontal forces through regularly spaced five-story braces. The towers, one 62 and the other 69 stories in height, connect by a bridge at the 39th level and rest on a base that encloses a four-story garden atrium. A great public galleria follows the curve of Columbus Circle.

Secondary tower-like facets comparable in scale to the apartment towers along Central Park West form a transition between the urban scale of the Upper West Side and Midtown. Setbacks in the two main towers accommodate five-story greenhouses that provide an amenity for the office workers and create a strong visual connection with Central Park.

Work on the center was halted due to the financial downturn and the withdrawal of Salomon Brothers.

The proposed design for the headquarters of Converse Network Systems at Ra'anana, on the outskirts of Tel Aviv, included offices and manufacturing facilities for 6,000 employees along with 4,000 underground parking spaces. The complex was to consist of eight office pavilions flanking a glazed community "street". The office buildings -- four and five stories high -- were to be set atop a floor devoted to manufacturing and services, with four underground parking levels below it. The linear office structures were to be set 32 meters apart, containing a series of thematic gardens with gardens, water features and recreational spaces. The largest of the gardens was to contain dining terraces and a health club opening to an outdoor swimming pool.

Surrounded by relatively tall commercial buildings, the Connecticut Center must assert itself. Its image evokes the sciences; its geometries are reminiscent of great astronomical instruments, challenging our curiosity. Two nacelles, shaped as segments of two great toroids, are perched side by side atop a podium. The structure of the nacelles is made of laminated wood lattice - a diagrid - that rotates about their surface in an ordered and repetitive geometry. Uniting the nacelles is a great roof platform in the shape of the surface of a partial sphere - an inverted dome. The geometries of each part intersect to create a cohesive and ordered whole. The Connecticut Center is organized into six levels, the first of which is the entry at the street. The second level is a podium, which features three floors of parking as well as offices and the museum's back-of-the-house areas. The deck of the podium extends Hartford's series of piazza, which also connect to the river abutting the site - these are the city's upper platform. The third and fourth levels of the Center, within the nacelles, are an exhibition and theatre spaces; the fifth level, also within the nacelles, is the upper mezzanine; the top level is the sky garden.
