House in Saishikada

Due to the instability of the existing retaining walls, the footings were extended deep into the load-bearing strata. The slabs are cantilevered to balance bending moments while preserving the natural topography. By layering these distinct spatial vectors, the house serves as a curated observation point that engages with its surroundings at varying depths.Stacked OrientationsLocated on a terraced hill in the suburbs of Midori City, Gunma, this two-story wooden residence occupies an embankment elevated three meters above the street. A long, rectangular volume was positioned to secure a southern garden while framing the expansive rural landscape unfolding below.The first floor is articulated as a linear sequence of living spaces, guided by four central columns. Along the longitudinal axes, the exterior walls are pleated, creating rhythmic alcoves that accommodate domestic functions internally—such as kitchens and window-side retreats—while forming sheltered voids externally for porches and equipment. To maintain an expansive interior free of structural partitions, the load-bearing walls were projected outward and rotated 45 degrees, effectively countering seismic forces from both directions.In contrast, the second floor emphasizes a longitudinal orientation. From the vantage points of the kids’ room and DJ booth—conceived as internal observation decks—the structural presence of the ridge beams becomes prominent. The void between these beams guides the inhabitant’s gaze toward the distant horizon, bridging the intimate interior with the vast pastoral scenery.
