Among Abraham's many well known hypothetical projects is "Seven Gates to Eden," a bold hand-drawn analysis of the suburban house, exhibited in the 1976 Venice Biennale, curated by Francesco Dal Co, and included in a 1981 show at the Yale School of Architecture, entitled "Collisions," curated by New York architect George Ranalli. Abraham's "City Of Twofold Vision, Cannaregio West," (1978–80), is sited in Cannaregio, the northernmost of the six historic districts of the historic city of Venice, Italy. Abraham also designed the "Les Halles Redevelopment" project (1980) for Paris, France, and "Interior" (2001), and his design for "The New Acropolis Museum" (2002) in Athens, Greece articulates new ideas about the contextualization of monuments. In 2002, Abraham contributed a poetic artistic response to New York's World Trade Center attack on September 11, 2001. Abraham's proposal is a poignant symbol to regain footing while envisioning a new future architecture for the City of New York.
