About Black Monolithic Wall 住宅屋

呢座雕塑感十足嘅黑色住宅坐落喺東京一個寧靜嘅住宅區。地盤入口窄,向後延伸,形成一個修長嘅形狀。喺遵守日本建築法規嘅同時——例如對鄰地嘅日照限制同建築高度限制——呢個設計嘅目標係善用呢個修長嘅地盤形狀,創造出充滿動感嘅空間。入口通道以一幅與建築融為一體嘅整體式黑色牆身作為特色,令外觀顯得格外奪目,而通往入口嘅懸臂式樓梯亦令整個進入序列更加豐富。

Unique Properties
This is a custom house plan for a parent and their child. Although the site is located relatively close to central Tokyo, its neighbor is a quiet residential area. It is an extremely narrow flag lot with no more than two meters wide portion fronting the road. Our aim was to create a dynamic space which can only be formed on a site with unique characteristics like this as well as to meet the strict building regulations in Japan.
Dimensions & Packaging
Site area: 84.39 m2
Building area: 48.82 m2
Total floor area: 114.60 m2
Number of floors: Ground 3 floors
1st floor: 50.47 m2
2nd floor: 50.38 m2
3rd floor: 28.56 m2
Height: Maximum height 9.38 m
Structure: wooden

Production Technology
The residential space is consisted of three layers. In order to provide a maximum volume of interior space while meeting the building height regulation, half of the first floor height is buried below ground level. The second floor is planned to be used as guest rooms, part of the public space. The void in the center runs through the second floor to the dining area on the third floor.
Design Challenge
In the typical design, disadvantaged by a narrow and elongated approach space, we were able to create a rich experience that entices visitors deeper into the property through a three-dimensional composition centered around an architectural boundary wall, 3 meters in height, integrated with the main residential volume in a sculptural form. This approach has successfully materialized an engaging journey for visitors.
Research
Research Objective: To maximize living space while clearing the strict height restrictions (sunlight regulation) on the north side of the site, the first floor is partially buried underground. Method: The underground portion is constructed with a concrete framework and undergoes special waterproofing treatment. Results: It was possible to ensure sufficient ceiling height on each floor. The dining room has a height of 3600 mm, and the bedrooms also maintain a height of 2900 mm.
Inspiration
First, to leverage the long, flagpole-shaped layout of the site, we envisioned the approach space as a sculptural design integrated with the architecture. Along the site boundary, we inserted a single boundary wall and designed it to incorporate elements such as stairs, a meter box, a mailbox, and lighting. This boundary wall will lead visitors to the second-floor entrance, providing a rich spatial experience along the way.
Project Duration
This project was completed in September 2020. The site is situated in a quiet residential area of Tokyo, yet it features an extremely dense layout of buildings. The conditions for access to the main road are strict, with only a mere 2 meters of frontage, resulting in a very narrow and elongated shape of the plot. The rear of the property is slightly wider, forming a typical flagpole-shaped site that resulted from land division.
Operation Flow
The first floor is a semi-basement, comprising a private space that includes the master bedroom, studio, and bathroom. In the bathroom, there is a jetted bathtub facing the tsubo-niwa, a small Japanese-style courtyard garden, with sunlight gently pouring in through the window. An overhead shower head, the width of one's shoulders, provides a relaxing bathing experience. The tsubo-niwa also serves as a light well, allowing wind and light to permeate each floor, creating a comfortable living environment.
