Rathnelly House

Rathnelly House is a minimal home located in Toronto, Ontario, designed by Studio VAARO. The concrete floor that anchors this transformation tells its own story of material ambition. Cast in place, it forms a continuous datum from which sculptural elements rise like geological formations. The dining booth nestled within kitchen millwork, the integrated bench at the stair landing, the media console – each emerges from this concrete foundation with organic inevitability. Here is craft operating at the scale of architecture, where the traditional boundaries between furniture and building dissolve into something more fluid and expressive.

This material strategy reaches back to the modernist experiments of the 1960s, when architects like John Lautner and Paulo Mendes da Rocha explored concrete’s sculptural potential in residential settings. Yet Studio VAARO’s approach carries a distinctly contemporary sensibility, one that prioritizes tactile warmth over heroic gesture. The concrete is paired with walnut-toned millwork that flows continuously from foyer to kitchen, creating material narratives that guide inhabitants through the expanded 140-square-meter addition.

The project’s most compelling innovation lies in its understanding of spatial efficiency as creative constraint. Working within the existing footprint of the Edwardian structure, the architects achieved a 60 percent increase in functional area through strategic vertical manipulation – lowering the basement slab by 1.2 meters while redistributing floor plates above. This vertical choreography speaks to broader urban pressures facing cities like Toronto, where intensification must happen within established neighborhoods rather than through sprawl.

The curved partition wall that divides living and kitchen areas exemplifies this multifunctional thinking. Beyond its primary role as spatial divider, it conceals ductwork, backs the intimate dining booth, and integrates with cabinetry to provide serving surfaces. Such geometric interventions reveal themselves as descendants of the space-saving strategies pioneered in postwar Japanese architecture, where every element performs multiple roles within constrained footprints.
