Warm and modern: a Washington family builds a contemporary home with comfort in mind.

The open plan for the living, dining, and kitchen areas promote easy circulation and a feeling of spaciousness. Each space still feels distinct: The deep, coffered ceiling in the dining room and the level change between the living and dining areas create separate zones and noise buffers.

Flexibility is key. Gail can be working in the kitchen while Ian draws at the table. "The living room is not just a place for adult conversation," Williams adds. "It is a place to watch TV and read the newspaper. And there is room for the kids' toys."

The simple, clean, cubist lines and warm white walls of the home are countered with natural materials, including mahogany cabinetry and bamboo floors. The muted palette continues upstairs in the master suite, which has a book-lined entertainment and sitting area.

First Floor. The kitchen island is also a divider, separating the cooking area from the dining space without blocking sight lines. The rich tones of the mahogany cabinetry contrast with the reflective glass-tile backsplash to add warmth.

In the living room, a sliding panel above the fireplace hides the TV. When closed, the mahogany panel creates a more formal atmosphere; slid to the side, it reveals the TV, giving the space a more casual, everyday feel.

Off the adjacent dining room, three room wide steps define the entry to the living room and also function as extra seating.

Second Floor. The master bedroom has a relaxation zone by the fireplace and the French doors, which open to a deck. Maple panels above the fireplace hide media equipment, keeping the room free of clutter.

In the master bath, an under mounted sink and adjacent vanity add to the sleek look. Towels are stored on open shelves for easy access. (By Jil Peters).
