Port-Royal Apartment by Mitchell Sweibel Studio
Situated on the 30th floor of the Port-Royal building in Montreal's Golden Square Mile, this apartment renovation by Mitchell Sweibel Studio reflects a quiet sophistication shaped by thoughtful spatial reconfiguration and a refined palette.
With panoramic views of Mount Royal as its backdrop, the 3,580-square-foot home distills the studio's architectural approach into a calm and composed interior.
Founded in 2021, Mitchell Sweibel Studio is a Montreal-based architectural practice that works across scales, from interiors to furniture, favoring simplicity, spatial order, and tactile materiality. Moving away from the structure of a large firm, the studio thrives on collaborative processes with local artisans and an attunement to site and context.
In the case of Port-Royal, inspiration stemmed from the building's own architectural legacy. Completed in 1964, the tower features a monumental lobby defined by noble materials, simple lines, and measured repetition. "Our goal was to introduce a contemporary language of design but remain faithful to the character of the building and its timeless architecture," says Mitchell Sweibel, founder of the studio.
A key gesture was to fully open the apartment to its extraordinary views. The original layout, fragmented and enclosed, obscured the three expansive horizontal windows overlooking Mount Royal. Stripping back these visual barriers became the project's point of departure, prompting a complete overhaul of the internal arrangement. Working within the constraints of a mid-century structure, the team navigated structural shafts and re-routed plumbing and ventilation beneath the slab in order to achieve full ceiling height and uninterrupted sightlines.
Central to the apartment's new configuration is a continuous axial wall that delineates served and servant zones. It reads as a sculptural presence within the home, accentuated through a shift in floor material, and invites movement while organizing flow. Square-jointed wooden flooring adds a sense of quietude, while the mass walls of the building, reimagined in lime plaster, echo the lobby's geometry and sense of permanence.
Throughout the home, a restrained palette and emphasis on texture support the studio's philosophy of durable elegance. Rough-sawn walnut cabinetry contrasts subtly against plastered walls. In the master bath, hand-made Japanese ceramic tiles introduce a sense of craft, while bedroom doors in custom back-painted glass add a cool material counterpoint. Hidden ventilation slots are integrated seamlessly within ceiling reveals, and magnetic lighting tracks offer flexibility without visual clutter.
What sets this home apart is not only its fidelity to the spirit of the original building, but its considered departures. Moments of misalignment, such as shifting thresholds between materials, inject subtle tension into the symmetry. These gestures, quiet and intentional, reflect the studio's interest in small architectural moves that encourage closer looking. "While the overall form of the apartment remains sympathetic to the order of the building, these subtle differences become apparent to the keen eye," Sweibel notes.
With this project, Mitchell Sweibel Studio has articulated a contemporary interior that honors context while embracing calm, material richness, and structural clarity, an approach that speaks to the studio's ongoing exploration of refined, intentional living.
