W. C. and A. N. Miller Development Co., which has build hundreds of houses in upper Northwest Washington and in the Potomac, is building for the first time in Northern Virginia.

The firm's project, called Spring Rudge, is a 50-acre tract with half-acre lots east of Reston. It is being developed into a community of 46 large houses priced around $200,000.

Four of the traditionally styled houses have been sold, said sales manager Michael Seay.

Seay Miller moved into Virginia to avoid some of the restraints placed on building in Montgomery County -- to participate in the growing Virginia market.

All of the Spring Ridge houses have three or four bedrooms, a family room and at least one fireplace. Chair rail and crown moldings are used as part of the interior finishing. Purchase prices include $500 for wallpapering to the buyer's taste and $1,000 for landscaping. The area is on a knoll just north of the Dulles non-access highway.

Nearby, Koury-Tipton Homes is building houses starting from about $140,000. Jacobsen Builders is also building in the $150,000 range at Hawthorne Estates in that area.

The neighborhood has attracted several dozen developers of large houses, most of which are priced between $130,000 and $200,000.

The Miller firm is building houses priced at $215,000 and up on two-acre lots in the Darnestown area, as well as a group of detached and 24 attached homes off Massachusetts Avenue in the Spring Valley area of Northwest.
