Haniyasu House: A Fusion of Architecture and Ceramics in Kamakura







Aatismo studio has masterfully transformed a traditional Japanese residence in Kamakura, known as Haniyasu House, into a unique multi-generational dwelling that celebrates the symbiotic relationship between architecture and ceramic art. The home, which derives its name from Japanese deities associated with earth, clay, and pottery, was originally erected in 1967 but required significant restoration following typhoon damage. Architects Keita Ebidzuka and Eriko Masunaga, alongside Ebidzuka's ceramic artist parents, embarked on this ambitious project, aiming to create a space where life and artistic creation intertwine seamlessly. The innovative design features external walls adorned with clay, soil, and various metal powders, meticulously applied to mimic the rich textures and hues of ceramic glazes, effectively paying homage to the family's artistic heritage.
The structural integrity of the original home was re-established by stripping it down to its fundamental timber framework, which was then fortified and expanded. Aatismo introduced four distinct, curvilinear volumes at each corner, crafted from sustainable materials and coated with a unique blend of waste products, evoking the impression that these forms have organically arisen from the earth. These extensions, shaped like trapezoidal prisms with softened edges, utilize a simple timber frame insulated with timber panels. The exterior finish is particularly noteworthy, incorporating bisque-fired waste clay from the parents' pottery work, layered with local soil and a plaster mixture containing iron and copper powders from metal workshops. This ingenious application results in streaked patterns, reminiscent of traditional ceramic glazing techniques, displaying a natural progression of colors from blue-green to warm orangey browns and green-greys. Internally, these new spaces present a raw, cave-like plaster finish, creating an intimate and earthy atmosphere.
Within the heart of the renovated Haniyasu House, the central area of the former structure now encompasses an expansive atelier, living room, and kitchen, elegantly framed by the textured, curved volumes of the additions. Sliding glass doors open this vibrant communal space onto a south-facing terrace, fostering a connection with the outdoors. Each of the three corner volumes serves as a dual-purpose area for individual family members, combining sleeping quarters with dedicated workspaces; the parents' areas double as pottery studios, while the architects' spaces are furnished with desks. The fourth volume, situated to the northeast, houses a traditional tea room that also functions as a guest bedroom, complete with tatami mats and a square skylight, offering a serene and introspective retreat. This holistic approach to design not only addresses the functional needs of a multi-generational household but also deeply embeds the family's artistic practices into the very fabric of their home, creating a living masterpiece that celebrates heritage, sustainability, and creative expression.
Haniyasu House is a testament to the power of thoughtful design, demonstrating how architectural innovation can be harmoniously integrated with artistic practice and environmental consciousness. By repurposing waste materials and drawing inspiration from ancient mythology, Aatismo has not only crafted a dwelling but has also woven a narrative of continuity, creativity, and ecological responsibility. This project exemplifies how architecture can transcend mere functionality to become a profound expression of identity and a beacon of sustainable living, inspiring future generations to find beauty and purpose in every element of their environment.
