Amid the severe housing crisis facing central Utah and the Wasatch Front and Back, coupled with rising land, construction, and material costs, STUDIO 125 presents an innovative solution for suburban densification. This approach demonstrates that it is both legally and structurally possible to add a second home for a family on an existing, relatively small parcel of land—going far beyond the traditional Accessory Dwelling Unit (ADU) model. Unlike typical developments, which often consume new land, potentially displacing pristine landscapes or agricultural spaces and requiring additional infrastructure, this concept reimagines land use by building on existing properties. By utilizing land with an already established structure and connections to road access and services, such a project minimizes the environmental impact. In contrast to the ADU model, typically limited to 700-1,200 square feet, this approach could provide spacious, comfortable living for an entire family while seamlessly integrating into the existing layout. By sharing access and infrastructure, this method fosters sustainable growth and reduces strain on the region’s resources.

STUDIO 125 advocates for a higher-density approach that minimizes the impact on a region. By utilizing an existing 0.36-acre, south-facing, wedge-shaped parcel with a 2,500 square-foot building located at its narrow south end, the property provides ample space for a generous 3,300 square-foot second home, each unit featuring private outdoor spaces. This approach emphasizes the enhancement of existing structures and the redensification of properties through the development of new buildings.

In compliance with Summit County's building and development code, which mandates that both the old and new buildings on a lot smaller than ½ acre be connected, STUDIO 125 introduces a 250-square-foot connector unit. This connector offers flexibility for future use, enabling the entire complex to function as a single, spacious home for a family of 7 or 8, or as two fully independent 3- and 4-bedroom residences.

Given the high demand for energy-efficient rental properties, STUDIO 125 presents a housing solution that meets Passive House standards, providing highly energy-efficient, comfortable living spaces designed to meet the growing needs of the area.
