The American Institute of Architects opens the doors to nine architect-designed homes for this tour showcasing a variety of residential styles. Sustainability, open floor plans, indoor/outdoor spaces, abundant light and a mixture of modern and traditional materials mark key features of this year’s houses. The tour's broad range of square footage from 2,000 sq.ft. to 6,500 sq.ft. and locations from Bellaire to River Oaks demonstrates that size and dollars do not limit excellent design.
