About Hat on the Ridge 山脊上的帽子

《山脊上的帽子》係位於日本鎌倉嘅一座兩層高木構住宅，附設畫廊。泥地板直接鋪設於基岩之上，方形金字塔屋頂覆蓋住一個無柱嘅空間。屋頂四邊低、中央高，每一邊屋頂都向上翻起，分別朝向唔同嘅景致——山、谷、村莊同天空，藉此形成四個各具特色嘅空間。喺四個角落，上層樓面被貫通至地面，連接上下兩層。古董以貼近日常生活嘅尺度展示出嚡。

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.
