Conceived and built with boat-like precision,the Aurora Seven houses an owner-occupied modernist apartment and three modest market rate, apartments inserted into a neighborhood of single family homes. This allows mixed income integration into an otherwise upper income neighborhood. The structure reuses an extant foundation while integrating a modern Structural Insulated Panel (SIP) structure. The Aurora 7 Building is energy-independent, with a geothermal ground loop system for heating and cooling and photovoltaic panels for electrical generation. All of the interior finishes are green building compliant, sustainably harvested materials. Further, reflective membranes and planted green roof technologies reflect heat avoiding contribution to the urban heat sink while lowering the building’s carbon footprint.
