In this collaboration between Studio TMOJ and Zeegers Kleinbouw, Omiyama proves to be more than a façade finish: it functions as an architectural instrument that brings together contrast, durability and expressive power within a clearly articulated extension.
Designed by Studio TMOJ, the addition is conceived as a legible, autonomous volume that deliberately distinguishes itself from the existing brick architecture. Materiality plays a pivotal role in this strategy. With Omiyama as façade cladding, the new volume acquires a strong, tactile identity that contrasts with its traditional context while maintaining overall cohesion.
The façade is executed in vertical Omiyama elements with a deeply charred surface layer. The texture is irregular and pronouncedly matte. In its fixated state, the wood appears a deep matte black; under sunlight, a subtle bronze glow emerges. This interplay between light and texture enhances the perception of the volume, giving the building a dynamic expression throughout the day.
The vertical rhythm aligns with the proportions of the tall glazed openings and accentuates the slenderness of the extension. The dark façade skin acts as a frame for the transparent openings, intensifying the relationship between interior space and garden.
Omiyama is crafted from hydrothermally modified Fraké (limba). Through the thermal modification process, the wood’s cellular structure is transformed, resulting in enhanced stability and durability. Combined with the deeply charred surface, this creates a weather-resistant and low-maintenance façade solution suitable for long-term exterior applications.
The execution by Zeegers Kleinbouw is defined by meticulous detailing and the precise installation of the vertical elements. Refined junctions around frames and transitions reinforce the monolithic character of the volume, while the natural variation between the boards introduces subtlety and vibrancy.
The “Paradox.” Burning wood to protect it.
It sounds contradictory — but it’s brilliant.
At ORGA, we’re big fans of biobased materials that truly prove their worth. Take our collaboration with Zwarthout | Shou Sugi Ban, for example. By charring wood using the centuries-old Shou Sugi Ban technique, a natural protective layer is created — without the need for paint or chemicals.
The result is a façade with character, built to last for generations. In the three recent projects, we’ve seen how it creates a robust, timeless appearance, while simultaneously contributing to refined, high-quality architecture.
Less maintenance, and a building that only becomes more beautiful with age.
That, to us, is what truly future-proof design looks like.
“We recently replaced the potted decked timber on our farmhouse in the Beemster region with Shodoshima semi-gloss from Zwarthout l Shou Sugi Ban. With special planks 25 cm wide, it looks great on a farmhouse. A very beautiful product and great service from Zwarthout l Shou Sugi Ban!”
”We chose Yoroi for several reasons. First of all, we like the Japanese classical technique used for burning the bamboo. Due to the burning technique Shou Sugi Ban, Yoroi has a fire class B and is maintenance-free. Finally, the black charred bamboo is a regrowable material and aesthetically matches our design perfectly.”
”As a gardener, it is an honour to work with such beautiful traditional products.
The delivery times are also great and you get friendly service.”
We have put together two Zwarthout | Shou Sugi Ban sample boxes: one for interior design applications and one for façade cladding.
That way, you can experience the attention, care and love we pour into each piece of wood yourself. And, of course, the beauty and exclusive looks the various textures have to offer.
