Champion of San Antonio Wins 2015 NSA Design Awards


National Sunroom Association CLEVELAND, OHIO - The National Sunroom Association (NSA) announced the winners of the 2015 NSA Design Awards at NSA's Fall meeting in Pittsburgh. The 2015 Design Awards mark the eleventh anniversary of the competition. Champion of San Antonio won in the Existing or Wood Roof Sunroom $20,000 - $35,000 category for the Rendon home. Champion of San Antonio was also a finalist in the Existing or Wood Roof Sunroom $35,000 - $50,000 category for the Lewis home.

Award Criteria

The National Sunroom Association Design Awards recognize excellence in the design and installation of sunrooms, solariums, and patio rooms. Almost 70 entries of sunrooms, solariums, and patio rooms constructed in 2014 were submitted for this competition. All entries were judged on the basis of 1) aesthetic appeal, 2) how well the sunroom, patio room, or solarium enhances the architecture and natural surroundings of the home or commercial setting, and 3) its interior appeal and functionality.

To increase the diversity of entries, all sunroom designs were judged by four different cost levels, as well as three different roofing types.

National Sunroom Association

The National Sunroom Association is a member-directed trade association dedicated to the advancement of the manufacture and construction of safe, energy-efficient and environmentally-conscious sunrooms, patio rooms, and solariums.
