Five developers yesterday submitted proposals to rebuilt the last large parcel of city-owned land in downtown Washington -- the $100 million-plus Gallery Place hotel, retail and office project.

The developers, four of which also submitted scaled models of their projects, presented similar plans for a single structure with atriums, skylights pedestrian walkways and buff-white exteriors.

One design, submitted by Landow & Co., is a three-part structure, containing an international design center, international trade center and luxury hotel that in concept are to be considered as one.

The one-block-square parcel is located at the Gallery Place Metro subway station between 6th and7th and F and G Streets NW.The site, which now consists of vacant lots and several old buildings, is across the street from the Hecht Co. downtown store and the National Portrait Gallery. It is also four blocks from the city's planned convention center.

Some of the plans propose connections with the Hecht Co. and also underground entrances to the Gallery Place Metro stop. Two of the plans propose at least 250 units of apartments or condominiums in the highrise structures.

Those submitting proposals were:

Gallery Center Corp., one of whose members is James L. Denson, president of the D.C. Chamber of Commerce.

Western Development Corp., in association with Ruby B. McZier, Larry C. Williams Sr. and Leonard L. McCants, all Washington lawyers.

Capital Landmark Associates, a team headed by the presidents of the city's four black-controlled financial institutions.

Gallery Place Associates, headed by William Zeckendorf Jr., a New York real estate executive and son of a prominent real estate magnate, with nine other principals.

Landow & Co., a Washington development company.

All of the development teams were required to have some minority participation in them. The deadline for submission of proposals to the city was 4:45 p.m. yesterday.

The Gallery Center proposal includes two 11-story office towers and a 13-story hotel, 101,200 square feet of retail space on two levels, a dinner theater, two movie theaters, restaurants, a ballroom, and a future health club.

Western's plan includes office space, 300 units of residential space, restaurants, a 250-room hotel, conference rooms and a health club.

The Zeckendorf proposal includes a two-level shopping mall, office and retail space, a 255-room hotel, a pedestrian esplanade, arcade areas and indoor access to the subway.

Capital Landmark Associates has proposed a 558-room hotel, 252 apartment units and office and retail space in a 13-story structure.

Landow's plan includes the three buildings with restaurants, discoteques, sidewalk cafes and specialty shops, with "unique speciality goods" predominating.

A decision on awarding the project is not expected until November.
