A house designed to meet the changing housing needs of the 1980s -- including skyrocketing housing cost, double-digit inflation and interest rates and energy shortages -- will be built by Lewis Homes of California this summer in Upland, near Los Angeles.

The unusual house, called the Style Setter 1980s Home and designed by Barry A. Berkus of Berkus Group Architects, will be sponsored by the Asphalt Roofing Manufacturers Association, according to Randall Lewis of Lewis Homes.

Lewis said that the house anticipates four major socio-economic changes that he expects to see in the 1980s:

A trend toward two or more unrelated adult heads of households living under one roof as housing costs make individual housing less practical.

Utilization of passive solar heating principles.

Wider use of attactive fire-resistant building products, such as three-dimensional asphalt shingles.

The 2,972-square-foot house -- main house plus a separate 375-square-foot "lanai room" or mini-guest house -- will be constructed next to models for a Lewis subdivision in north Upland, he said.

"There are two widely separated master suites in the house, and the lanai room can be used as another suite," he said, adding that the house will be constructed on a half-acre lot and will have to sell for at least $250,000. The price could well be higher.

S. M. Lewis of ARMA said that the steeply pitched pyramid-shaped roof of the Style Setter house is a perfect showcase for the latest generation of asphalt shingles and shold demonstrate that asphalt shingles can compete in the expensive home market with wood shakes and shingles and tile.

"Several manufacturers produce asphalt shingles that are fire resistant while giving the light and shadow display of heavy shakes," he said.

Randall Lewis admitted that zoning laws and financing are obstacles to the sharing of the Style Setter house by unrelated adult groups and predicted that when the house is sold -- after it has been on display for several months -- it probably will be purchased by one buyer.

"Most communities forbid unrelated adults from living in a house in an area zoned for single-family houses," he said. "As housing gets more and more expensive, this may be changed."

"As for financing, we'll probably see one person or couples buying houses of this type and renting suites to their housemates," he added.
