Washington architect Hugh Newell Jacobsen has won his sixth first honor award in the "Homes for Better Living" competition of the American Institute of Architects and Housing magazine.

Over the years Jacobsen has won 12 awards in the competition - and a total of 64 architectural prizes altogether. But, he says, "who's counting?"

The most recent award is for a house in Wayzata, Minn., which has been described as a series of sharply roofed black barns overlooking a lake.

The sections house the master bedroom, a library, a living room, dining room-kitchen-solarium, two-car garage and a guest house.

The Wayzeta house (built for a family that has requested anonymity) has three bedrooms and two and one-half baths in the main section. The library, solarium and the lake views from the south side of the house are highlights.

On the exterior, vertical butt joint cedar is siding is painted black to contrast with snow that covers the landscape from November to April. Even the roofs are done in black asphalt shingles.

The only two-story section is the master bedroom "barn," which has two other bedrooms on top. There's a partial basement. Walls are heavily insulated, according to Jacobsen, and heat is gas-fired forced warm air. There are two fireplaces. But no air conditioning-it's not needed!

In back of the guest house is garage space for the snow plow, which the residents often use to get to nearby Minneapolis.

The house, which is featured in the May issue of Housing, has about 3,000 square feet of living space. Built on a 20-acre lot next to a lake, the property is valued at about $500,000.

Architectural Record last fall reported that Jacobsen "consciously employed the vernacular forms of the region" in designing the house. The magazine noted that the main structure has rooms "lined up against the view with their glass walls offset to break up the elevation. The major spaces are linked by a long circulation gallery with a circular stair at one end."

The Jacobsen imprint can be seen in Georgetown restorations and remodelings and in several dozen new houses in this area.

"What's important is the house where you live," Jacobsen has maintained." Architecture is space that should make us look and feel better."

A native of Grand Rapids, Mich., Jacobsen grew up here and studied architecture at Yale after graduating from the University of Maryland in 1951. His own home is a one of the 80 old Georgetown houses he has "laid hands on."

Out of the modest, 10-person Jacobsen office on the second floor of a nondescript Georgetown building have come designs for the Bolton Square town houses in Baltimore, award-winning town houses in Columbia, a weekend house at Riva near Annapolis, college libraries, a motor inn in Nashville, three hotels and university buildings in Greece.
