This project is a renovation of one unit within a two-family house located in Saitama City, Saitama Prefecture.

While preserving the spacious and open living–dining area with its gently sloped ceiling, we focused on updating the interior finishes, built-in furniture, and fittings, as well as the kitchen, bathroom, and lighting fixtures, without altering the existing layout.

The client requested a space where their collection of art and decorative objects could be beautifully displayed. We designed the renovation with the intention of creating an interior that highlights those items.
To emphasize the framed artworks, we minimized the visual presence of elements that might compete with them—such as doors and window frames—so that the interior would act as a quiet backdrop for the art.

Custom-built elements such as bay window sills and kitchen walls were finished with mitred, flush corners to achieve a flat, frameless appearance.
For the sunlit living room windows, we considered potential expansion and contraction due to temperature changes. The frames were made slightly proud of the wall for durability but finished with thin, white-painted boards that visually blend with the wall, minimizing the sense of framing.

Walls intended for hanging artworks were given a plywood backing so that hooks and fittings could be easily installed, and the painted surface allows for simple repair of any marks left behind.

The choice of materials and colors was kept simple to harmonize with the existing wooden ceiling. This allows the client’s artworks, furniture, and lighting to stand out more vividly.
Other rooms follow the same design approach, with consistent wood tones and wainscoting details to create a unified atmosphere throughout the home.

The client requested a sliding sash window between the corridor and the living–dining area. We designed a custom-made wooden sash that allows flexible opening positions while maintaining a simple, refined appearance.
The frame and muntins were crafted in wood, with hardware carefully concealed through trial and error. This element became a pleasant accent that visually connects the entrance area and the living space.

Based on the design and construction experience from this project, AIDAHO added a new “sliding sash” model to our long-running Interior Window Series.

Through this renovation, we created a home that gently supports the client’s lifestyle—one that embraces daily living while celebrating the art and interiors that enrich it.
