TOKYO — Symbolplus designed its new office located in a timber building owned by architect Akio Hayashi. Hayashi’s long-standing advocacy for natural materials became the starting point of the renovation. As a result, the design team avoided synthetic materials in favor of working with those that already existed. Rather than pursuing visual impact, the project focuses on continuity―between architecture, material, and time.

The design preserves the original timber structure as much as possible. New elements follow the building’s rhythm, proportions, and warmth, allowing old and new to coexist without contrast.

Material choices reinforce this attitude. Red earth sourced from Ishikawa was applied in layered plaster by artisans, its tone carefully adjusted to resonate with the timber structure. Shoji partitions were made from reclaimed Tosa washi originally intended for disposal. As the paper was too thin for architectural use, it was layered to achieve durability and translucency.

These shoji flexible partitions allow the space to shift between openness and privacy. In meeting areas, they conceal shelving and equipment when needed, maintaining visual calm without erasing function.

Innovation appears through restraint. Shoji panels slide without metal fittings, relying on traditional carpentry techniques. Rotating ceiling panels reveal lighting only when required, reducing visual noise.

By building upon what was already there, the project demonstrates how modest interventions can extend the life of architecture while remaining socially and environmentally responsible.
