The Sienna Villas at Longview in Lee’s Summit, Missouri, were designed to have the feel and luxury of Tuscany, with the hidden safety and energy-efficient advantages provided by the ARXX ICF wall system. The complex consists of 124 total units and the builder is offering homeowners savings on utility costs and temperature-stable comfort all year ’round. Even more comforting than their heating and cooling bills is the fact that the ARXX ICFs give their homes the strength to withstand severe natural disasters.
