Most grown-ups spend their workdays inside, so coming home to a well-appointed outdoor space for dining, entertaining, or just kicking back has become an increasingly high priority for homeowners. Builders and designers respond readily with amenity-laden exterior rooms that carefully balance outdoor exposure with sybaritic character. Capturing natural views and prevailing breezes is as important as offering fire for warmth and cooking, ample seating, and protection from weather. Architect Keith Summerour advises,“Keep as many existing trees as possible, and build into the land in a clever way.”
