都市生活者である施主が、リタイア後に移住をして、自給度の高い田園生活を始める為の家。
斜面段々畑の上にて敷地を囲む360°の緑の展望を楽しめる事、厳しい寒暖を最小限にする工夫、十分な太陽光発電が望まれた。
敷地にて最大限風景を享受する配置と平面とし、夏の日射を遮り屋外作業空間となる深い庇をふわりと廻し、二階、デッキ、太陽光パネル屋根の各層を緩やかにずらし重ね、段々畑にとけ込むようにした。
一階天井は傘状垂木が360°に広がり、そこに二階をもぐらせ一階の気積を抑えながら二階外壁面を減らし空調負荷を抑えている。デッキ下に廻る灌漑用ホースは夏に井戸水で一階屋根と二階外周をクールダウンする。
An elderly couple wished to retire to the country and to start self-sufficient life. After much searching, an ideal site was found in the Tokyo suburb. This site was perched on the hill surrounded by natural landscape and afforded pleasant views; a mountain to the south and preserved forest to the north and east.
The two main requirements for their house were; to enjoy, within a sense of protection, the surrounding nature as well as to benefit from a structure that moderated climatic variations in a sustainable way.
The new home was to be a cozy place, that would facilitate their transition from urban to country dwelling.
Considerations of vehicular access, forest preservation and the contour-topography resulted in the house being located in only a small part of the plot, as well as the final form.
Corners are rounded not acute-angled thus the house sits comfortably with a soft external geometry which enhances its reciprocal panoramic setting: its aspect within, and its prospect without. The effective roof and eave responses to the climate here were studied carefully that brought us a new form.
Eave projections are used in order to provide shelter from sudden storms and summer-sun, alike, the eave is extended most to the southeast to provide a largest shadow to protect the outdoor working area from severe summer heat in the afternoon.
The contours of the terraced hillside influences the staggered section and the dwelling’s wide range of vistas. To emphasize this multiplicity of panoramic views the ceiling rafters are exposed and resemble umbrella-like, spokes.
The upper volume sinks in the lower volume to reduce air volume and surface area of outer wall and thus minimize heating energy.
The cold water extracted from the well is conveyed to the sponge-like hose around under the terrace to cool the roof in the summer.
Solar panels are adequate for the household demands and the roof geometry ensures that they do not visually intrude within proper angle for the solar gain.
