Ordinary House

This is a small home located on the border of a residential neighborhood and a forested area where development is restricted. Because the lot is lower than the road facing it, access is via a bridge leading to an entrance on the second floor. The shape is nearly cubic, with a triangular terrace notched into one side. Large windows are used only adjacent to the terrace and the atrium, which is located on the southeastern side of the structure overlooking deep forest. A number of stimulating elements overlap in this corner of the house, including variations in light, floor level, and ceiling height. These elements weave together to generate complex phenomena within the very simple shape of the structure. I conceived of these intersections as places where the family living in the house would gather together.

Architect, Shinichiro Akasaka answered some questions about the project.

Did the house as it was actually built differ in any way from your original design? Tell us about any difficulties you encountered and how you overcame them.

By covering one part of the wall around the triangular terrace with reflective aluminum panelling, I was able to bring the changing colors of the forest into the home in an abstract form. The triangular shape surrounded with glass and aluminum also serves as a megaphone that amplifies surrounding sounds and brings them into the house. I expected this to happen but it ended up working even better than I’d thought it would. In addition, I had hoped the exposed-beam ceiling would add a sense of expansiveness and light to the space. Once it was built  I discovered it reflected the colors of the forest in ways I hadn’t imagined.

How is this project similar or different from others you have worked on?

Rather than being swayed by passing trends, I want to design structures from universal elements.  I want to produce designs that are logical and have a sense of inevitability to them; to read the building site and be true to its voice. I take this attitude on all my projects, including this one, but in this case the time available for design was extremely limited. So I decided to drop all pretenses, let the tension out of my shoulders, and draw lines intuitively. I feel like what I did was find reason and order within the lines once they were on the page. This was a reversal of my normal process, where I start with a certain logic and then draw lines to fulfill it.

What did you learn from this project? What do you want to bring from this project to future work?

In that this house employs only simple shapes and minor design innovations, it can perhaps be called an “ordinary house” of the modern era. Yet simply by manipulating the use and combination of so-called ordinary elements like light, air, sound, and color, I was able to create a complex indoor environment rich in variations. I’d like to use this concept of “ordinariness” as a center point for exploring various directions in the future.
