陶芸家の両親と建築家の娘夫婦のための自邸の増改築計画。
最古の素材である土を主題とし、現代の陶芸の技術を参考に新しい景色を持つ土壁で増築する。タイトルのハニヤスとは土や陶芸の神の名前である。家族全員が創作に関わる職住一体の二世帯住宅であるため、生活と創作が渾然一体となった原初の住処を目指している。

Extension and renovation project of the house for ceramic artist parents and architect daughter and her husband. The project focuses on earth, the most primal material, and uses earthen walls with colors and textures inspired by contemporary ceramic techniques to expand the existing home. Haniyasu is the name of the god of soil and ceramics. All family members are involved in the creative activities, the aim was to create a primordial dwelling where life and creation are integrated into one.

両親は共に陶芸家をしており、鎌倉の山間にある築50年を超える家で、土を捏ねたり釉薬をかけたり絵付けをしたり、電気釜で焼いたりとすべての作業を家の内外で行っている。そこに建築家である娘夫婦が同居し、家は家族全員が創作に関わる職住一体の二世帯住宅となる。

Both parents are potters and do all the work inside and outside the house, such as kneading, glazing, painting and firing in an electric oven in their 50-year-old house in the mountains of Kamakura. Their architect daughter and her husband move in and the house becomes a two-family home where all family members are involved in the creative activities.

既存母屋をスケルトン化し、三内丸山遺跡の集会場のような家族が自由に集まったり作業をしたり出来る大きな一つのオープンな中間領域のような空間とし、その四隅に土で出来たかまくらのような増築部を付加し、プライベートな活動をする独立性の高い各自の巣のような閉じた空間をつくる。

増築部の外壁は、敷地の土や素焼きした土などを混ぜたものに、鉄や銅の金属粉などを添加して反応させて釉薬をかけて焼いたときに現れるようなマチエールを表現し、陶芸の魅力の一つである偶発性や経年変化を受け入れて時間を内包するあり方を目指す。内壁は敷地の土と漆喰を混ぜて壁と天井を同一素材で仕上げ、包まれるような空間とした。

自然と一体となりながらも異質な存在感と力強さをもつ立ち姿や、建築や陶芸の枠を超えた土の表現、そして生活と創作が一体になったような住まい方や、既存の母屋と増築部の対比というような、複数の要素が混ざり合って統合的で多義的な存在となることを意識している。

The existing walls of the main house are removed to create a skeleton structure, turning it into a large, open space reminiscent of an ancient communal hall like those found at the Sannai-Maruyama archaeological site. This space allows family members to freely gather and work. At each of the four corners of this open area, extensions made of earth, shaped like igloos, are added. These extensions serve as independent, enclosed spaces for private activities, functioning like individual nests for the occupants.

The exterior walls of the extension are made from a mix of soil from the site, unglazed terracotta and metal powders such as iron and copper. By reacting these metal powders, a texture similar to that seen in glazed and fired ceramics is achieved, embodying the charm of ceramics, including its unpredictability and the acceptance of aging over time. The interior walls and ceilings are made by mixing soil from the site with lime plaster, finishing both with the same material to create a space that feels enveloping.

This architecture aims to blend with nature while also maintaining a distinct presence and strength. It transcends the conventional boundaries of architecture and ceramics through its unique expression of earth. The residence facilitates a lifestyle where living and creativity merge seamlessly. Furthermore, there is a contrast between the existing main house and the new extensions. By blending these various elements, we aim to create a cohesive and multifaceted spaces.
