Rundtjernveien Apartment Renovation by Studio Et al: A Minimalist Revival in Oslo

A Raw, Honest, and Textural Apartment Transformation in Norway

Located on the outskirts of Oslo, the Rundtjernveien Apartment Renovation by Studio Et al reimagines a 100 m² functionalist residence through a philosophy of reduction, material honesty, and quiet Nordic warmth. Completed in 2024, the project centers on revealing the building’s original structural essence while introducing crafted timber interventions that soften and redefine space.

The renovation reflects a contemporary Scandinavian approach — restrained, tactile, and rooted in architectural clarity. The design emphasizes exposed concrete, sanded structural surfaces, and natural timber, creating a home that feels grounded, evolving, and intimately connected to its modernist context.

Stripping Back to Reveal Spatial Purity

Instead of adding layers, the architects performed a complete material reset. Floors and walls were sanded back to their structural core, exposing raw surfaces and allowing the apartment’s functionalist character to emerge. This reductive strategy establishes an aesthetic of authenticity — a space where structure and material speak for themselves.

Selective insertions of Douglas fir define intimate zones. Thick timber boards sit directly atop the structural slab, creating gentle platform transitions that articulate program and encourage tactile living. Each gesture strengthens spatial clarity without closing off views or disrupting the apartment’s long sightlines.

Enhancing Light, Length, and Spatial Flow

The existing concrete structure features load-bearing slabs and shear walls, shaping a slender open-plan layout. Studio Et al builds on this linearity by designing a central, generous hall that acts as a connective spine, guiding movement and extending visual continuity across the apartment.

Daylight becomes a primary architectural element. Lightweight timber frames with fibreglass infills softly diffuse light into deeper interior zones, bringing warmth and luminosity while preserving privacy and material calm.

Raw Materiality and Crafted Details

Material choices balance rugged authenticity with crafted intimacy. A custom concrete kitchen island — cast with local aggregate — anchors the living and kitchen spaces, serving as a sculptural threshold between social and private functions.

Complementary built-in furniture in pine and stained oak forms pockets for daily rituals: tying shoes, storing towels, placing everyday objects. These pieces embrace simplicity and usefulness, reinforcing the tone of understated Nordic living.

A Home Designed for Adaptation

The project embraces circular thinking and future flexibility. Architectural elements are intentionally separated — meaning surfaces, furniture, and platforms can be removed, replaced, or reconfigured without disturbing the primary structure. This strategy not only extends the lifespan of the apartment, but also supports changing needs, lifestyles, and sustainability goals.

A Scandinavian Expression of Constant Evolution

The renovation embodies a quiet architecture — one that celebrates unfinished textures, layered time, and the beauty of structural truth. Natural materials in their original tones harmonize with the exposed framework, crafting a home that feels open-ended and continuously forming.

Rundtjernveien Apartment stands as a testament to Norwegian minimalism: a space where restraint creates richness, and where architecture remains flexible, honest, and deeply human.
