Passive House with Ralston Eco Homes

Nestled in a new neighborhood development in Swisher, Iowa, this five-bedroom, single-level home redefines what a spec home can be. Designed with the everyday buyer in mind, the home blends the comfort and livability of a market-ready floor plan with the performance of PHIUS CORE Passive House certification, proving that exceptional building standards and broad market appeal can share the same address.

The home's open layout invites effortless living, anchored by generous shared spaces that flow naturally from room to room. Large windows draw in natural light while a thoughtfully oriented site takes advantage of seasonal sun exposure, keeping the home bright and comfortable year-round. Window sizes and orientations were carefully calculated as part of the Phius design process to maximize daylight level and minimize summer solar heat gain. The walk-out basement extends the home's living possibilities, offering a spacious recreational retreat that opens to an outdoor patio below and connects to the main level deck above.

Every space was designed with the end user in mind to create a home that feels as good to live in as it performs. The house and all its internal systems were designed to provide the owner with increased indoor air quality, thermal resistance, and durability.

At its core, this project is about possibility. The same floor plan that had already found success in the local market was thoughtfully adapted and elevated, demonstrating that high-performance, certified passive house construction is not out of reach for the spec home market. It is a home built and designed to inspire what comes next.
