Toronto architecture studio UUfie has breathed new life into a 1970s chalet nestled in the wooded area of Ontario. With their latest project, the firm has reinvented the revamped Belfountain House, set on the Niagara Escarpment, perfectly weaving itself into the fabric of its surroundings over a sprawling three-acre site.

Designing with nature’s contours

The innovative design preserves the chalet’s original northern half, while the southern portion reimagines the structure within its existing footprint. A sweeping, elongated roof mirrors the slope of the land, uniting both halves in harmonious balance. Irene Gardpoit, UUfie’s cofounder, emphasized the studio’s philosophy of integrating the house into the landscape rather than merely establishing it on the site.

A hike through home

The chalet spans 430 square meters, offering four levels of carefully crafted spaces organized to mirror the natural ascent and descent of the terrain. Reflecting on this design, cofounder Eiri Ota likened the home’s layout to a hiking experience, where architectural elements gradually reveal themselves through progression, view shifts, and intentional pauses.

The firm reimagines an interior of continuous landscapes

Externally, the combination of white stucco and black wood forms, accented by black metal elements, creates compelling visual geometry. Inside, the design flows without harsh boundaries, creating a continuous, organic environment. Key communal areas are nestled under pitched roofs, while open spaces cascade downhill, connected by unique staircases. This is one of the many ways the studio renews traditional architectural designs.

Innovative spaces for modern living

One striking feature is a suspended net, serving both as a divider and a hammock between the dining and lounge areas. This inventive element introduces a sense of openness and engagement. Additional facilities include a sauna, gym, and a uniquely designed guest room at the lowest point, featuring a skylight and polycarbonate walls to create a serene ambiance. Once again, the design team reimagines functional spaces with creativity.

A balanced material palette

Inside, materials like reclaimed elm and concrete floors interplay with red steel beams and wooden rafters to deliver both warmth and tension in the design. This balance of textures and elements speaks to the studio’s intent to marry refinement with rawness. The architects reinterpret these palettes to achieve a harmonious yet dynamic environment.

Founded in Tokyo and now thriving in Toronto, UUfie brings its sensibility across various domains, from furniture to architectural designs like a Canadian lakeside cottage and an Ontario medical clinic. The transformation of the Belfountain House is captured by the lens of Ema Peter.
