I think that handing over a house means handing over the stage of life. The appearance of the building is not a complete form, but the customer thinks about his own affluence as a director, and grows the space that will be the stage to make it easier to live. I am very happy to see how I live like that.

Architects Nobuya Kashima and Aya Sato speak with a smile.

From now on, it will be important for each and every one of us to think about a "rich life". It is important to listen to customers' stories, research them, and work together to create a space where you can feel their richness.

These two people also faced themselves, thought about "richness", and created a stage in Karuizawa that embodied it.

A forest hut created by the "richness" of spending time with your dog

Before, while spending time with Mr. Sato, who started to keep a dog, he realized that there were surprisingly few places to stay with him in the house. Since I work in Tokyo on weekdays, I can go out with my dog on weekends and enjoy nature. It does not necessarily have to be wide or gorgeous.

Such an image of the richness of life in my own way was the catalyst for the birth of the "Forest Hut".

Designed with nature

Every time they went to Karuizawa and witnessed the forest, soil, and water as they were, they felt that they couldn't create more value than the natural ones. After deciding to build a "forest hut" in this area, the design point was how to enjoy the existing nature.

  • Designed to create a path for wind and rainwater

    Buildings can also be described as producing foreign substances in nature. Therefore, I lifted the floor so as not to block the road where the wind was flowing from the mountain and the road where the rainwater was flowing.

  • Designed with solid wood to enjoy aging

    I wanted to set a simple building in nature as much as possible, so instead of using concrete, reinforcing bars, and plaster walls, I used solid wood for the interior and exterior, which naturally fades when exposed to the elements.

    • Designed to allow you to walk around the site like walking in the woods

      For convenience, we do not have an entrance near the road, We made the best use of the natural environment so that we could enjoy the approach to the building while getting out of the car and walking between the trees. A wandering line has been set up.

      In addition, a chair is placed in the sleeper circle in the center of the site to read a book or relax with a dog so that you can enjoy various ways even in a small space.

Thank you for the living things

In the life of "Forest Hut", you can feel the scenery that changes with time even during the day. A white world with fog right after waking up in the morning, a blue sky with the sun, and a night sky with shining stars. If you expand from one day to one year, the changes that nature weaves, such as fresh greenery, autumn leaves, and snowy scenery, will be closer to you than life in Tokyo.

Man-made buildings are built in the woods and in nature, and humans come later. That is why the consciousness that "I am allowed to live in that place" grows. Insects that fall and cannot crawl up will be woken up and returned to the forest. When I live in a city, I feel that humans play a leading role, but in the forest hut, I feel that humans are also a part of living things, and I think the world has expanded.

Two people who talked to me.

A world that realizes the richness for oneself and expands. Why don't you look for it too?
