Hechinger Co., the chain of specialty retail do-it-yourself home centers, has selected Inglewood Business Community in Landover as the site of its new corporate headquarters.

"We looked at more than 10 different locations in the suburban Washington, D.C., area," said Bob Ruth, Hechinger's property manager. "Inglewood offered the most advantages. It gives us excellent visibility from the Capital Beltway and accessibility to our existing facilities, employees and clients."

Hechinger has had its headquarters on Pennsy Drive in Landover for several years.

Construction of the 207,000-square-foot building, expected to be completed in the summer of 1989, will begin this spring on 13 acres of land bought from McCormick Properties Inc., the developer of Inglewood. The first phase of construction will be on 123,000 square feet; the second on 84,000. An atrium corridor of reflective glass will connect the two buildings.

"We purposely chose a practical but aesthetically pleasing design which will also give us the potential for future expansion," said Roger Wright, Hechinger's senior vice president for real estate.

Huntmar Associates Ltd., meanwhile, has bought 8.5 acres of land in Inglewood and has begun construction of a two-story, $8 million research and development building at 9475 Lottsford Rd.

Bristen Office Concepts Inc., a Lanham-based manufacturer of interior office products, is leasing 60,000 feet of the Huntmar building's 126,800 square feet for its new national headquarters and marketing center. Bristen is a partner in the project, which also will serve as a showcase for its products.

"We outgrew our present facilities and this building will not only allow us expand, but it will also give us the opportunity to tailor it to our corporate image and function," said Louis Cimaglia, president of Bristen.

The building was designed by House Reh Associates of Dallas and will feature skylights, 24-foot ceilings, a water garden and a second-floor mezzanine with balconies.

Inglewood has 10 buildings with a total of 680,000 square feet of space for offices and research and development. When completed, the complex will have 16 to 20 buildings with 2.6 million square feet and a 260-suite hotel and restaurant.

The 230-acre office park is home to Motorola Communications & Electronics Corp., Digital Equipment Corp., Bendix Field Engineering Corp. and the Washington Bullets' administrative and sales offices.
