The Light Welling House is standing on a narrow site. So the designers had to think about how to bring the sunlight inside. Their solution to ensure natural lighting was to design the stairs as a path of light that would be able to distribute natural light to each room. The stairs are made of perforated metal to let the light seep through, and the stairwell has glass walls to allow the light to shine into each room as well as to lead and reflect the light from the top to lower levels. The positioning of the stairs was also a critical factor and therefore decided carefully, calculating the altitude of the winter sun.

It is easy to become immersed in preconceived ideas called "common sense" and "experience". But these can at times hinder the creation of truly natural and comfortable spaces. It is therefore essential to keep an open mind. Pure design work is a process that involves identifying what is truly needed, and placing the necessary quantities in the necessary places. Architecture, whether it be a small house for a single family, is the accumulation of this fundamental work process, outweighing all elements of purpose, scale, method of construction, or structure. This is the very essence of our design.
