Decisions by the D.C. Board of Zoning Adjustment (BZA) last week cleared the way for the Army and Navy Club to construct an addition to its Farrugut Square building, which will make the structure 11 stories high, and for the Seventh Day Adventist organization to expand its printing plant at 6856 Eastern Ave.

The Army and Navy Club, at 17th and I streets NW, will replace its present glass-enclosed eighth floor and add three more stories. Part of the enlarged building will be rented out for office space. Earlier plans for an addition were rejected by the BZA last month on the grounds that the proposed structure would not be in keeping with Farrugut Square architecture.

The Seventh Day Adventist Review and Herald Publishing Association won a variance to add a third story to its plant in the Takoma section of Northwest Washington. At a hearing June 20, Takoma residents asked that the BZA require the printing plant to retain the mansard roof of the original building, but the BZA declined to make retention of the mansard roof a condition of the variance.

In other actions, the BZA:

- Denied the application of Maud Moreland for a variance to build a single-family detached house at 2744 Rittenhouse St. NW. The lot, in a single-family residential zone, was too small, according to the board.

- Denied the application of Bender Associates for a special exception to allow a roof structure more than 18 1/2 feet high on a building to be built at 1120 G St. NW., the site of Neisner's variety store. The structure would have housed air conditioning units and other utilities. The board agreed to waive the rear yard requirements for the building.

- Approved, with modifications, the application of Arnold and Alex Litman to build eight rowhouses at 4625 through 4639 Minnesota Ave. NE. The board required the developers to redesign the facades of the houses, submit a landscape plan, omit the proposed carports and place parking spaces at the rear of the planned development.

- Approved for five years the application of John F. and Betty M. Belfiore for a special exception to continue to operate a car repair garage in a commercial zone at the rear of 1437 Newton St. NW.

- Denied the application of 1515 Limited Partnership for a variance to use a building in a special purpose zone at 1501 16th St. NW as consulting offices. Only offices of doctors, lawyers, architects and non-profit organizations are usually allowed in special zones.

- Approved the application of Dorothy F. Clark for a variance to continue to use a house at 1437 33rd St. NW for apartments.

- Approved the application of Anthony E. Gallo for a variance to build a rear addition to a house at 1539 A St. SE.

- Approved the application of William L. Walde, D. Gay Walde and Stephen B. Shapiro for a variance to place parking spaces within 10 feet from the wall of a home containing windows at 1925 16th St. NW.

Denied the application of Morris Battle for a variance to construct a private garage, next to a house, at 1823 Wyoming Ave. NW.

- Approved the application of the Bank of Columbia for a variance to use a building at 1426 K St. NW as a storage facility.

- Approved for two years the application of Hysong Realty Company, Inc., for a special exception to continue using 1304-1312 N St. NW as a parking lot.

- Denied the application of Benjamin F. Childs for a variance to build an addition to a house at 4922 Brandywind St. NW.

- Approved for five years the application of St. Paul's English Lutheran Church for a special exception to continue to house a Montessori School in a residential zone at 3600 teverett St. NW.

- Approved the application of L.E. and P.L. Waldorf for a special exception to change the use of a basement in a residential zone at 500 Eighth St. NE from a restaurant to a bookkeeping office.

The D.C. Zoning Commission, in a separate meeting last week, approved a zoning change to allow the expansion of Rollins Funeral Home at 4339 Hunt Place NE. At a hearing June 18, residents of the area supported the proposed change, calling the funeral home a needed facility. No opposition to the change was expressed at the hearing.
