Construction is expected to begin next month on a New England-style shopping and office center on a 13-acre site at Georgetown Pike and Walker Road in Great Falls, Va. And work is scheduled to be started this summer on another shopping center in the same area.

The nearly $5 million, 100,000-square-foot development, which would be the first sizable shopping and commercial facility in the low-desnity, rural residential Great Falls area, has been designated Village Centre by a partnership of developers headed by Douglas A. Cobb, a commercial-industrial builder, and Joseph L. Jarvis, an exporter. S. Michael David of David Associates in McLean is handling leasing.

The Village Centre will include 18 low-rise buildings clustered around a landscaped mall area under which there will be parking for 400 cars.

"Our buildings, designed by Dickey & Dickey, architects, will be in the style of Strubridge Village, Mass., with cedar shake roofs, dormers and shutters," said Dickey, who heads Commercial Industrial COnstruction Co.

A resident of Great Falls, he indicated a desire to make the Village a community center providing services. One low-rise building will be a market housing various food offerings, similar to a small farmer's market, he said.

John Hentschel of CIC did the site design, with engineering participation by the Mills & Petticord Partnership, Cobb said. He added that he has Fairfax County approval for the site plan in the area, and no zoning change is needed. There was no opposition from the Great Falls Citizens Association, he added.

Cobb siad tha tpublic water service is available but that a subsurface drain field will be set up on 5 of the 13 acres to handle sewage disposal. A hydronic heating and cooling system will be installed.

Meanwhile, the Georgetown-based Western Development Corp., headed by Herbert S. Miller, plans to build another small shopping center with emphasis on a food chain, Safeway, as a tenant on another corner of the intersection of Georgetown Pike and Walker Road in Great Falls.

Dennis J. Galanis, an officer of Western Development, said that Safeway has signed to take 32,000 square feet and Peoples Drug will have a 10,000-square-foot facility in the one-story shopping center that also will have 20 other small stores - none a fast food operation - for a total of 82,000 square feet. About 6,600 square feet will be office space.

Salditt, Lipp and Helving is the architect-engineering firm for the Great Falls Shopping Center that Western Development plans to start this summer. Galanis said that a special exception had been obtained for parking on the 11.7-acre site but that the site approval and building permit have not yet been obtained. He added that a recreation area will be built in back of the shopping center for Great Falls citiznes and that the entire development would be heavily landscaped.

The shopping areas nearest to Great Falls are at Tysons Corner and Sterling, Va., about seven miles away.

And DRG FInancial Corp. announced that a $2.8 million mortgage loan commitment has been obtained for permanent financing of the Potomac Promenade Shopping Mall now under construction on a 4.3-acre site on Falls Road, near River Road in Potomac Village, Md.

The developer is a limited partnership, headed by general contractor Richard H. EIsinger, whose firm is building the mall.
