Habitat for Humanity partnered with Sundt Construction for its Tucson branch. The project features an unused warehouse that was reworked into new administrative offices. Sundt Construction worked on the structure over the course of several months, during which 5,950 square feet of space was gutted, renovated, and turned into a usable modern office space. The project design preserved several features of the previous warehouse, like exposed ductwork and concrete floors, but added many new amenities, like heating, ventilation, air conditioning systems, and additional windows for more natural light. Everything was performed at a reduced rate to provide the nonprofit group with a beautiful and functional new space.
