Construction of an 10-story, $7.7 million, 176-unit apartment building will begin late this summer at the north-east corner of 15th Street and Rhode Island Avenue NW.

The National Housing Partnership, a Washington-based organization that is privately owned but created by Congress to stimulate the construction of rental housing, is the general partner in the project. The 19,800-square-foot site, a parking lot for the past decade, was purchased recently for $560,000 from Baltic Investment Co.

George M. DeFranceaux, chairman of NHP, said the project is being processed for Section 220 mortage insurance under an urban renewal areas program of the Department of Housing and Urban Development. He said the building will have a roof-top sua-deck and sauna facility. A general constractor has not been selected yet.

To the north on 15th Street, which has been the scene of considerable private urban renewal and rehabilitation in recent months, NHP also is the general partner in the recently started construction of the 171-unit Campbell Heights high-rise at the former Dunbar Hotel site at U Street. It will provide housing for the elderly under a HUD financing program.

The unit will come under HUD's Section 8 housing assistance payments program, which provides tenant rent subsidies. Eligible tenant need pay no more than 25 per cent of their adjusted income toward rent.

The $6.1 million building is being named for the late architect Leroy Campbell. His firm, Sulton-Campbell & Associates of the District designed the project. The building's 55.175-square-foot site was purchased by Campbell Heights Associated from the D.C. Department of Housing and Community Development for $77.592. Forest City Dillon, Inc. the builder, will use a system of precast concrete panelized components and a kitchen-bathroom module in construction of the structure. Forest City Dillon recently built a high-rise for the elderly at Fort Lincoln new town in Northeast.

Utilizing the panelized system will enable the developers to finish the building by November, the NHP said.

The building will have 153 one-bed-room units with aproximately 568 square feet of living area and 17 one-bedroom units with 683 square feet. Community facilities will be located on the first floor of the building, which will have an ajacent paved patio for outdoor recreation.

In recent years the National Housing Partnership has been the catalyst for the construction of more than 35,000 dwellings in 36 states, including the 526-unit Rock Creek Terrace in Montgomery County and other projects in Alexandria, the District, Reston and Laurel.
