This two-story ADU, crafted from pre-fabricated Passive House panels, were craned into place in just two days, a testament to careful planning, precision and efficiency. Partially attached to the main dwelling, it shares a utility space while carving out its own quiet retreat in the backyard. The upper-level bedroom frames views of the surroundings through high performance windows, inviting fresh air and natural light with connection to the landscape. Below, a recycled concrete patio extends the living space outdoors, tying the structure to the garden. Designed for resilience as much as comfort, the ADU incorporates fire-resistant detailing, ensuring durability for years to come. With its compact and efficient layout, the dwelling offers a calm refuge - the perfect place for reading, writing, and quiet reflection, while embracing sustainable building practices and low embodied carbon.
