About Hat on the Ridge 住宅、画廊

《山脊上的帽子》是位于日本镰仓的一栋两层木结构住宅，内设画廊。夯土地面直接坐落于基岩之上，四角锥屋顶覆盖着一处无柱空间。屋顶边缘低垂，中心高耸。四条屋檐各自向上翻起，分别朝向不同的景致：山峦、山谷、村落与天空，由此形成四个各具特色的空间。在四个角落处，二层楼板被切开直通地面，将上下两层贯通相连。古董则以日常生活的尺度陈列其间。

Unique Properties: Earthen floor connects with the bedrock, and square roof opens to the landscape - The space was vertically diversified by adding the floor on the ground and levitating the roof over the earth. The roof lowers down towards the roof edge and heightens up in the center. Each of the four edges of the roof opens to a different view: the mountain, the valley, the village, and the sky. Responding to these rich surroundings, each edge is flipped up to make four different spaces with different views.
Dimensions & Packaging: 2story wooden building
Width 6825mm x Depth 6825mm x Height 6970mm
Tags: Villa, Gallery, Pit dwelling, Dorma, Cats, Vista, Mountain, Village, Sky, valley
Production Technology: Earthen floor connects with the bedrock, and square roof opens to the landscape. Each of the four edges of the roof opens to a different view: the mountain, the valley, the village, and the sky. Responding to these rich surroundings, each edge is flipped up to make four different spaces with different views.
Design Challenge: The site is covered in a soft sediment over the surface of bedrock. The site was above the road level by just the thickness of the soil, which we chose to remove by the shape of the building footprint to put the foundation directly on the bedrock. The approach from the road is dug into this soil as well, gently sloping up towards the house. By placing a structurally stable pyramid roof over the simple square-shaped plan of the house, we created a pillarless space under the single roof.
Research: From a gallery-like space to a house with a gallery.
When the construction was first completed, the ground floor entrance hall and upper floor bookshelves were gallery-like spaces for displaying antiques and other items that were the owner's hobby.
By displaying them within the scale of the living space, the works of art feel more familiar, and visitors can easily imagine the scene in which they will be placed in their residences.
Inspiration: The origin of the idea is a pit dwelling that blends in with the mountain range. Removing soft sediments over the surface by the shape of the building footprint to put the foundation directly on the bedrock, a semi-subterranean-like space buried in the earth is created. The space was then vertically diversified by adding another floor above the ground and levitating the roof over the earth.
Project Duration: The construction started in in September 2018 and finished in May 2019 in Kamakura, Japan.
Operation Flow: Cut through the floor in the corners - In the corners where the roof edges were left unflipped, the upper level floor is cut through to the ground to connect the two levels.
Flip up the roof edges - Each of the four edges of the roof opens to a different view: the mountain, the valley, the village, and the sky. Responding to these rich surroundings, each edge is flipped up to make four different spaces with different views.
