项目名为“东京之家”,位于日本东京市中心人口最稠密的地方,是一栋由UNEMORI ARCHITECTS事务所设计建造的私人住宅。该住宅占地面积仅为26平方米,总建筑面积51平方米,结构简单坚固,选材新颖美观,堪称城市高密度地区的住宅建筑范本。

The Japanese architectural office UNEMORI ARCHITECTS has completed an innovative, geometrically structured small house, called House Tokyo. Located in a densely populated area in central Tokyo, the private residence comprises a tiny footprint of just 26m2 and a total floor area of 51m2, showcasing an architectural paradigm for urban densification.


由于坐落于东京市中心,项目的场地面积十分狭小,几乎处于周边住宅的夹缝之中。业主夫妇希望UNEMORI ARCHITECTS事务所能为他们设计建造一栋供两人居住的房子,作为他们的临时城市住宅。为了应对城市密度带来的挑战,建筑师设计了这栋占地面积仅26平方米,总建筑面积51平方米的小房子,通过利用框架结构、增加天花板的高度,以及大面积的开窗,在紧凑的建筑体量中营造出宽敞舒适的室内空间体验。

Located in central Tokyo, House Tokyo was built on a tiny vacant spot in close proximity to the neighboring houses. Contacted by a couple who got hold of this land, UNEMORI ARCHITECTS was requested to build a house for two that would serve as a temporary city house. The architects reacted to the challenges posed by urban densification by developing a compact, yet spacious small house with a footprint of just 26m2 and a total floor area of 51m2 by making use of a suspended structure, an increased ceiling height and many large windows.

The façade of the compact house is dominated by industrial corrugated iron, opened up by large windows. The outer walls of the small house are partially set back, creating an increased exterior wall surface and different ceiling heights ranging from 1.9 meters to 4.7 meters. For House Tokyo UNEMORI ARCHITECTS realized a geometrically structured framework. The framework of House Tokyo was built with wood which can still be seen in the interior design of the residence. Furthermore, by setting back the outer walls, a terrace area was created on the first floor.

House Tokyo is based on a simple floor plan with a semi-basement, a first floor and a terrace area. The bedroom and bathroom are located in the semi-basement which is illuminated with natural daylight. The open-plan kitchen and dining area were placed on the first floor where the spacious overhead area is dominated by the wood beams of the house’s framework.

While each floor is assigned a function, the spaces are connected through open floor plans and offset levels which enlarge the space and counter the smallness of the house. Additionally, thanks to the suspended structure and exterior design of House Tokyo the air and daylight circulation was improved.
