The Washington Metropolitan Area Transit Authority wants to sell or lease 17,000 square feet and air rights on the southwest corner of 14th and I streets NW. That's the site of the east entrance of the McPherson Square Metro station due to open in July, a site that was purchased for $1.6 million five years ago. A large building with a mix of retail and office space is envisioned by WMATA, which has issued a 24-page prospectus loaded with details. Proposals are due July 1. Developer Gerald Miller and associates are constructing a 12-story building over a subway station at Connecticut Avenue and L Street NW - the first downtown building to be built in recent years without underground parking. But then, it's as close to a Metro stop as possible. In Rosslyn, WMATA has contracted to sell air rights and "density credits" at the station entrance to Stanley Zupnik and Associates, who plan a 350,000 square foot building over and near the entrance. A June groundbreaking is planned.

John Sower, the young director of the non-profit, New York-based National Development Council, grabbed the attention of a crowd of D.C. building industry folks on a recent evening when he talked about commercial revitalization in some areas of downtown Baltimore and other cities. Using slides, lots of specific information and a glib delivery, Sower really got through to a mixed audience that included D.C. Council member Nadine Winter, builder Joseph Geeraert, developer Theodore Hagans and realtor Dorothy K. Winston. Now the word is that Sower's organization may come into our downtown to do a similar catalytic job on the H Street corridor in NE.

Have you noticed that something's happening on an undeveloped corner of MacArthur Boulevard and Arizona Avenue NW? The man making it happen is Larry Stander, head of Stander Associates, Inc., and formerly president of the Suburban Maryland Home Builders Association. Stander's group bought three small lots totalling 20,000 square feet from John Fagan of the Housing Guidance Council, who bought the rambling log house (where he lives) and ground a few years ago. Stander paid $80,000 for the land and plans to build three brick houses with about 3,300 square feet of living space and offer them this fall for $160,000 to $180,000. Each will have two fireplaces and a big kitchen. Stander also plans to build a house on a lot acquired on Alton Place NW.

At a recent seminar on rehabilitation of apartment buildings, property manager Loren Simkowitz set the tone for fellow members of the Institute of Real Estate Management. There are three reasons to redo apartments, he said: social responsibility, satisfaction and financial reward. He maintained that the real estate bromide about the three most important factors being "location, location and location" is being replaced by a trilogy of "imagination, imagination, imagination" for apartment ownership and rehabilitation.
