Gillian Gillies Reimagines Sustainable Design as a Warm Embrace

In the rapidly densifying landscape of Toronto, where a growing array of boisterous architectural statement pieces compete for attention, a new home designed by interior designer Gillian Gillies stands as a welcome reprieve. Sustainability, so often associated with clinical engineering, soaring towers, expansive campuses, and stark, performance-driven aesthetics, is here reimagined as a “warm embrace.” Located in the upmarket “urban village” neighborhood of Leaside, the Net Zero Ready Home project proves that advanced environmental stewardship and joyful, idiosyncratic interiors can coexist.

The project is the result of a tight collaboration between Gillian Gillies (the designer’s eponymous practice), Dewson Architects, and builders Cliff & Evans. While the technical foundation is rooted in passive house principles—featuring meticulously tested air and moisture control layers to ensure a consistent year-round temperature—the sensory quality of the home is defined by texture, color, and family connection. “Comfort was paramount,” Gillies says, “and that meant a home that was properly constructed as well as [comfortable furniture].”

Gillies, originally from Edinburgh, brings a sensibility rooted in the permanence of neoclassical and Georgian architecture, translated here through a palette of natural materials including white oak, walnut, and wool. Each room is tailored to its intended function, while bold floral wallcoverings and textured tile add personality. Rather than the sterile “newness” typical of contemporary high-performance homes, the interiors embrace deliberate juxtaposition.

“We don’t perfectly match textiles,” Gillies explains. “Instead, we like a little bit of tension, a little bit of a mismatch that makes the home feel more settled.”

This philosophy is most evident in the communal spaces, where the design explicitly fosters human interaction. A double-sided sofa in the living room invites simultaneous yet distinct modes of engagement. A floating box window seat in the foyer provides a quiet nook for reflection. The color story—a grounding base of greens and blues punctuated by vibrant flashes of yellow and red—mirrors the family’s love of travel and the natural world.

Throughout the four-story structure, strategically placed architectural and decorative lighting shapes the mood. A Lutron HomeWorks system seamlessly transitions the atmosphere from energetic to intimate. Sculptural pendants from Montreal-based boutique producers Lambert & Fils and Gabriel Scott add a layer of contemporary craft. Vintage Brazilian furniture and Oaxacan woven baskets reinforce the space’s warm, tactile quality.

Ultimately, this Toronto home stands as a testament to the idea that thoughtful architecture can improve everyday life. By prioritizing the wellbeing of both the planet and a specific family, Gillies created a structure that does more than just store carbon; it’s a space that holds life in all its complexity.

“We create homes to be lived in and not simply looked at,” she says. In striking this careful balance, the designer has created a home that will undoubtedly last through the generations.

  • Jungle Keva

    Situated in Tulum, this small boutique hotel rises between the trees, in which the main concept consisted in preserving 70% of the existing vegetation in order to build around it. By achieving this, every space of the project is always in relation to its natural surroundings. The hotel has five 50m2 lodges, formed by a double height room, a mezzanine or “tapanco”, a terrace and an indoor-outdoor bathroom. At the back of the lot the social areas are located, with a dining space and yoga pavilion hanging in cantilever over the pool. The main idea of this water element is to be extruded from the ground in between the vegetation. For this reason, two old zapote trees were preserved, which look as they were rising from the pool itself. All the project is composed by local materials, as well as low maintenance and natural textures, which provide a warm atmosphere to the buildings. A particular finish found on the walls is “chukum”, a Mayan stucco characteristic of the region, which uses a tree resin to give its distinctive color, appearance and durability. The objective was to use materials that age with dignity, so that with the passing of time the architecture acquires character and a deeper sense of belonging. The different volumes of the complex are scattered along the lot, between the trees and stone paths, which provide a sensation of being in a small village in the Mayan jungle. Throughout the design process there was a search for pure forms and natural materials that could blend with the surrounding context. In a sense, Jungle Keva is like an abstraction or simplification of vernacular architecture, easy to read, simple and with a social, natural and economic conscience.
