"Block-Wall"Residence, Karuizawa, Nagano, Japan,

Japanese architecture practice nendo designed a private residence with block-walls made of "CO2-SUICOM", an eco-friendly carbon removal concrete.

The block-walls adjust the line of sight, a creative solution essential in securing privacy from passing traffic and pedestrians while acting as a foil for basking in the natural surroundings.

The design concept was to build the house with concrete block walls that would serve as filter screens. Besides, the material used deserves special attention: “CO2-SUICOM※” blocks, made by replacing a portion of cement, with an industrial byproduct and adding a carbon dioxide-absorbing material for less CO2 emissions during production.

Approximately 2,050 blocks are staggered in parallel rows to create five 3m-high walls. The living space is designed to “fill in the gaps” in between. Calibrating the block angles by three degrees to fit each room condition ensures privacy in the bedroom and bathroom, while also providing a spacious ambiance in the living and dining rooms. Ultimately, the design transpires into blocks arranged in a gradient-like pattern.
