Built around a centenarian Fir tree, the Shell Residence flows through the forest thanks to its organic, yet very strong structure. Tokyo-based ARTechnic Japan designed the stark white building to last in harmony with nature.

The Shell Residence is immersed in Nagano prefecture´s peaceful conifer forests, where it creates a stark contrast with its durable white facade. The house is located in Karuizawa, a popular weekend retreat for Tokyoites that is just 10 minutes away from the capital by Shinkansen. The residence was built around a centenarian Fir tree and is made from long-lasting, low-maintenance concrete, which shelters the home from the forest’s humidity and cold weather.

The Shell Residence is definitely a departure from traditional Japanese houses – it’s a striking, curvaceous shelter that seems to have landed from outer space. The outdoor wooden deck is made from locally sourced wood and it acts as an extension of the interior floors. The Shell Residence´s interiors are light, airy, and winding. Because of the house´s unique curvaceous interiors, the furniture is custom-made from strong, hard oak.

The floors are made from local cherry trees, and they exhibit a gorgeous red tint that contrasts with the oak furniture. The interior layout is very minimal and consists of two differentiated levels: the lower ground is used for public space, while the top floor is reserved for private use. An automated centralized system controls the house´s humidity, heating, and ventilation, optimizing energy use.
