Japanese minimalist interior
Clay Plastered Walls & Dark Minimalism
The house is unified by a palette of natural materials, including clay plastered walls that offer warmth, depth, and tactile texture, lending the space a serene, grounded quality.
Natural Stone Slab Wall Frame
A striking natural stone slab wall frame anchors the living space, introducing permanence and sculptural contrast against softer interior elements.
Charred Timber Wall with Hidden Bathroom and Storage
Perhaps the boldest architectural gesture is a charred timber wall, which conceals a hidden bathroom and integrated storage—demonstrating Polysmiths’ mastery of discreet functionality.
Tatami Room with Dark Clay Plaster
The top floor includes a custom-designed tatami room with dark clay plaster, blending traditional Japanese design with modern London living. The space offers a tranquil escape, functioning as both a guest room and meditation area.
Bespoke Fluted Timber Carpentry
Throughout the home, bespoke fluted timber carpentry wardrobe doors add rhythm and refinement, underscoring Polysmiths’ attention to artisanal detail and texture.
Dark Walnut Staircase with Curved Walls
A custom dark walnut staircase with curved walls acts as the sculptural centerpiece, flowing naturally through the home and softening transitions between floors.
Wabi-sabi in Chelsea
This project reflects Polysmiths’ commitment to sustainable luxury, precision detailing, and cross-cultural inspiration. Influenced heavily by Japanese architecture, every decision—from the framing of openings to the selection of switches—was deliberate.
