Wooden Blocks into ‘Lumbar Curtain’ Facade in Tokyo by Tsukagoshi Miyashita Sekkei

Wooden Blocks into ‘Lumbar Curtain’ Facade in Tokyo by Tsukagoshi Miyashita Sekkei

In the past several years, we have seen a tremendous increase in the timber structures, thanks to the advanced technology of glulam and engineered wood. The latest project by Japan-based architecture and design firm Tsukagoshi Miyashita Sekkei also shows the varied facets of using timber blocks. The studio used small wooden blocks to create the lumber curtain facade of a building complex in Minami-Azabu, a district of Minato, Tokyo, Japan. The practice has renovated the entrance of the building by creating a dotted screen which is formed by cypress lumber, which is generally used in the construction of old temples and has an odour of car exhaust.

Sturdy and Aesthetically Pleasing Lumber Curtain

The Lumber Curtain façade covers the 2-storey, which helps to protect the space from noise, harsh southern daylight and heavy traffic.


The firm designed this lumber curtain taking reference from old temples. The screen consists of cypress lumber and M6 stainless rods.


Vertically, two lines of rods penetrate the lumbers and the horizontal rods connect each columns.

The beautiful composition gives it no hierarchal appearance, aiming to offer visually appealing look from the front and the back.


Moreover, the structure is sturdy enough to resist wind pressure, while allowing an ample amount of sunlight to pass through the foyer.


Folded Shape

The shape of the lumber curtain is partly folded to display the entrance doors, which is giving it an appearance of a curtain made of lumber.


The lumber of 100mm depth along with less represented joining rods seem different according to the eye direction as one moves away or close to the screen.
