Perched along the southern coastline of Yokosuka City in Kanagawa Prefecture, House in Yokosuka by RID is conceived as a quiet retreat from urban life, shaped by proximity to the sea and the soft presence of white sand and wind-worn trees.
Intended as a weekend home for a city-based family, the project draws its interior language directly from the coastal landscape, cultivating a sense of ease and immersion rather than retreat.
The site sits moments from the beach, where locals gather at sunset and the ocean breeze moves freely through the surrounding vegetation. This relationship with the shoreline informs the interior approach, where material continuity and tonal restraint dissolve the threshold between inside and out. Rather than positioning the home as an object against its context, the interiors are shaped to feel like a natural extension of the beachfront, encouraging long views and unhurried occupation.
The home is arranged as a small compound, composed of a main volume, a multipurpose annex and a garage. Internally, this separation allows functions to be clearly articulated while maintaining a relaxed, villa-like atmosphere. Circulation between the buildings is mediated by a floating plate with extended eaves, creating shaded transitions that temper light and movement throughout the day.
Granite plays a central role across floors and surfaces, chosen for its resemblance to pale sand and cut into 500 x 500 millimetre modules aligned with the structural grid. Inside, walls and ceilings are finished in custom plaster infused with sand aggregates, lending subtle texture and tonal variation. A gentle gradient finish enhances depth without visual noise, reinforcing a consistent material language across the home. By carrying the same materials indoors and outdoors, the interiors resist clear boundaries, allowing light, texture and atmosphere to move freely.
Planting selections further soften the interiors’ relationship to their surroundings. Tropical species such as olives and fountain palms introduce a warmer palette that contrasts with neighbouring vegetation while remaining restrained. Decorative stones of Kiso origin from Gifu Prefecture are scattered throughout the grounds, their beige hues echoing the interior surfaces and reinforcing a unified colour story.
