Traditionally styled houses in the $50,000 to $90,000 price range are currently being built by nine companies at the new planned community of Burke Centre in Fairfax Couty.

Milton V. Peterson, oprating general partner of the Burke Centre Partnership, which is developing the 1,200-acre community near Burke Lake, said this week that sales have been strong in the early stage of development. He said one builder, Souhtern Engineering Corp., already has sales contracts on the 46 houses it plans to complete this year in the Twin Lakes neighborhood.

Another builder, Centex Homes Corp., set up a trailer sales office and sold 32 houses in its Winston Meadows section before any model homes were up, Peterson said. Between them, he added, Ryland Homes and Washington homes, Inc., also have sales contracts for 100 houses - more than half of their buildings lots. Woodland Enterprises and S&M Construction Co., Inc., have 20 sales in their joint development of 43 homes called Bryce Farms, where some houses are ready to be occupied. Senate Construction, Inc., and Poretsky & Starr, Inc., also are building in Burke Centre.

William L. Berry Co., Inc., has started 10 of the 100 houses it is building in the Woodberry section of Burke Centre; models will be open in April.

Peterson said there are no more lots available for builders this year. He added that Poretsky & Starr plan to put up townhouses this year in the wooded Burke Woods neighborhood, where the firm also is building its single houses.

"Because this is a spring after a rough winter," Peterson said, "our community is really not looking its best now. In fact, we're in an ugly stage with a lot of clearing, road building and costruction taking place. By summer we hope to have our orientation center completed to provide an introduction to the community and the location of the varied developers."

Burke Centre is expected to have a population of 15,000 by the end of the decade.
