A FEW YEARS AGO, Mary Evans, an English teacher at the World Bank, decided to reorganize the interior of her modest two- bedroom Cape Cod home. Architect Mark McInturff of Weibenson & McInturff moved walls and altered the living spaces. As he redesigned the house, he separated the living and dining areas with a partition wall, a technique that made each room seem larger. To give the new wall character and integrate open shelves with the rest of the wall, McInturff used half-round pine molding -- the kind that sells for a few cents a foot -- to divide the partition wall into subtle bands of the color taupe. And the job was done -- at least so Mary Evans thought.

She purchased new living room furniture to finish the interior, but it was all wrong. She needed something that would be a part of the room, not intrude into it. After looking at many small, light- colored pieces, Evans decided to have McInturff design furniture to go with the interior -- a task new to the architect.

After much research and model building (the model furniture is now in a doll's house owned by McInturff's daughter Marisa), he came up with simple painted pine furniture that would reinforce the half-round style established in the architecture. The three pieces in the living room -- a sofa, an upholstered bench and a coffee table -- all rest on bases that duplicate the baseboard moldings in the room. The buffet in the dining room, with a deco look, repeats the same curves.

Evans says the pieces cost less than those she rejected in their favor. The effect is at once distinctive and, like the rest of McInturff's design, modest in scale and detail. For Mary Evans, the house is now complete.
