After 11 years and an investment of $200,000, investor-developers D. F. Antonelli, Kingdom Gould and John W. Lyon have dropped their grandiase plans to redevelop the 27-acre, 435-unit Falkland garden apartment complex at the head of 16th Street just across the District line in Silver Spring. The triumvirate has not renewed its lease on the property, which had been planned as a complex of high-rise office buildings, apartments and a convention center. Antonelli said that an offer to buy the property was rejected ny the owners, descendants of the Blair family involved in three different partnerships. It was a matter of "time and money" and "waiting until 1961 for high-rise zoning," said Antonelli. The site is adjacent to the new Metro station in downtown Silver Spring, so it is not unlikely that 40-year-old brick rental complex will be redeveloped or upgraded and sold as condominium ownership units in the early part of the 1980s.

Edmund J. Bennett, whose firm built Carderock Springs and other contemporary subdivisions in this area before he sold it to a national firm several years ago, is back in the business as a consultant to Capital Mortgage Investments, a Washington-based investment trust.

He said that the designs will be by Keyes, Condon and Florance and tha Furman Builders of Rockville will do the construction lending by Riggs National Bank and permanent loans for buyers from Century National Bank. "CMI will probably be developing more residential lots in Fairfax County as the result of foreclousres," Bennett added.

Washington real estate investor-developer Angelo Puglisi recently made his first trip ever to Houston, where he was impressed by the no-zoning development of that fast-growing city. "It seems to work well for Houston," said Puglisi, who also visited friend Ken Aspromonte, the former Senator infielder and Cleveland manager, who now is a Coors distributor in Houston. . . . Near the former Golden Parrott restaurant, soon to become a Booeymonger, Puglisi is building a few town houses that probably will be in the medium-expensive category.
