A $12 million mixed-use complex of condominium apartments and office buildings, to be called Arlington Gateway, is planned for the Ballston area in Northern Virginia by two attorneys who are now full-time developers.

C. Daniel Clemente said that two nine-story buildings are planned for the acre-plus site on Fairfax Drive between North Utah and Vermont streets, an area which seen considerable building and redevelopment since the Ballston Metro station went into service. If approval from the Arlington County Board is granted, Clemente said that he and partner C. Edward Taylor will begin the project in late summer.

Taylor and Clemente, who in 1973 developed the Tower Villas condominium apartments in the same area, said that the Gateway project will consist of 180 condo apartments and 108,000 square feet of office and retail space. Salditt, Lipp & Helbing designed the structures to appear as one building.

The efficiency and one-bedroom apartments will average about 600 square feet and will be priced from $61,000 to $69,000.

Taylor and Clemente currently are developing the Randolph Square condominium town houses that sell for $155,000 in the Ballston area, and they have plans to begin a second phase of that development.

"County planners have given us a great incentive to produce affordable housing near Metro stops with their mixed-use concepts," Clemente said.

Although they have been developing real estate under the corporate umbrella of Aries Investment Co. for more than a decade, the developers also were partners in the law firm of Taylor, Clemente & Brock on Leesburg Pike in Alexandria. Clemente said he and Taylor recently sold their interests in the firm to Stanley Brock, who continues to operate the firm that has specialized in settlement work in Northern Virginia.
