The raffle drawing for a million-dollar Centreville house, scheduled to be held last Saturday, was postponed by the organization holding the fund-raiser because of slower-than-expected ticket sales.

The raffle, organized by the Women in Military Service for America Memorial Foundation, is to raise money for a memorial honoring women who served in the military. It is to be built in Arlington National Cemetery, with no federal tax money.

"Although we've sold lots of tickets . . . we haven't nearly reached our goal," said Wilma Vaught, a retired Air Force brigadier general and president of the board of directors of the foundation.

"As a nonprofit organization, the board regretted the need for the extension, but {we} had to assure this effort was profitable and helped raise the funds necessary to build the planned memorial."

According to foundation officials, about 24,000 tickets have been sold for $25 each. The foundation hopes to sell 250,000 tickets.

One million tickets were printed. The postponement of the drawing does not change the minimum odds of winning, which are one in 1 million, because no more tickets will be printed, officials said.

The house was built by Landmark Communities of Alexandria. President Scott Herrick and foundation officials said Landmark deeded the house to the foundation for a share of the raffle profits. Neither Herrick nor the officials would say how much money will be paid to Landmark.

The raffle drawing, now scheduled for Feb. 23, is sanctioned by the D.C. Lottery and Charitable Games Control Board, which approved the postponement.

The 6,000-square-foot new house, at 6301 Barnesdale Path, features a master bedroom suite with a whirlpool tub, a brick courtyard adjoining the bedroom suite and library, a two-car circular drive-through garage, a small pool with goldfish, cedar deck with a hot tub and blue stone patio, and two gas fireplaces.

The memorial to women veterans would be erected by late 1992. Designed by New York architect Michael Manfredi and University of Maryland professor Marion Gail Weiss, the monument is expected to cost $25 million.
