RD House by Wanawa Studio explores the contrast between contemporary minimalist architecture and the warmth of Japandi-inspired interiors. Defined by a sculptural composition of sharp angles, sloping walls, and a distinctive inclined roofline, the building embraces a restrained palette of light-toned materials to emphasize its geometric form.
The use of white as the dominant exterior color creates a clean architectural canvas, allowing the building's edges, planes, and structural details to become the primary visual elements. This approach extends into the interior, where natural wood surfaces, understated finishes, and functional built-in cabinetry introduce warmth while maintaining a cohesive design language. Rather than treating furniture as an independent element, selected cabinets are conceived as extensions of the architectural form, translating the geometry of the facade into the interior. In the bedrooms, the tatami-inspired concept introduces a grounded, minimalist atmosphere, prioritizing simplicity, comfort, and efficient use of space.
A defining aspect of RD House lies in its unconventional spatial organization, which places the main residence on the upper level while dedicating the ground floor primarily to service and supporting functions. This arrangement accommodates a spacious carport, service rooms, and a secondary living area, allowing the primary family spaces to remain distinct from daily service activities. Recognizing accessibility as an essential part of residential design, Wanawa Studio incorporates a ramp connecting the ground level to the main house, providing an alternative to stairs and facilitating access for elderly family members.
The upper floor accommodates the principal living, dining, and kitchen areas, three children's bedrooms, a master bedroom, a walk-in closet, bathrooms, and a balcony. This configuration establishes a clear hierarchy between communal and private spaces while supporting the family's daily routines.
Constructed using concrete, RD House relies on the material's versatility to realize its angular geometry and defined architectural masses. The predominantly light-toned finishes enhance the perception of volume and allow the sharp wall intersections and sloping planes to stand out without relying on excessive ornamentation. In contrast, the interior introduces timber finishes and integrated warm lighting to soften the overall atmosphere.
Functional cabinetry, carefully considered storage, and a consistent material palette help maximize spatial efficiency while reinforcing the relationship between architectural form and interior design. The result is a residence that balances visual clarity with domestic warmth, where the exterior's bold geometry meets the interior's understated Japandi sensibility.
Through RD House, Wanawa Studio approaches residential design as an integration of architectural expression, practical planning, and inclusive living. The separation of service and primary living functions, the incorporation of ramp access for elderly occupants, and the translation of exterior geometry into interior elements reflect an emphasis on how a home performs beyond its visual appearance.
Completed in 2026 in Serang, Banten, the 400 m² residence on a 225 m² site demonstrates how a restrained material palette, a distinctive architectural silhouette, and thoughtful spatial organization can work together to create a contemporary family home.
