reBuild Workshop reimagined a two-story timber-frame townhouse as a light-filled, high-performance home through a comprehensive renovation and vertical addition. The project introduces a dramatic double-height kitchen, expansive new window openings, and a third floor with a landscaped roof terrace — all designed to meet rigorous Passive House standards. A new façade of slate-colored brick and warm wood screens balances privacy with daylight, while a rear window with horizontal louvers admits soft northern light and limits heat gain. Above, a canopy shelters the terrace and supports a rooftop solar array that generates the majority of the home's energy. Inside, natural materials and a towering window anchor the design, drawing daylight deep into the heart of the home and framing views of the garden below.
