A pitched green roof that works with every element

The sloping Sempergreen green roof system completes the biobased concept both visually and technically. This pre-cultivated Sedum roof system forms a living, insulating layer that buffers rainwater and supports biodiversity. The reinforced carrier layer ensures strong root anchoring, essential for sloped roofs, while the underlying water-retaining fleece provides natural cooling in summer. Together, they stabilise the roof, reduce energy demand and create a thriving microclimate for bees and butterflies.

Sloping green roof: a natural extension of biobased living

A Sempergreen green roof is more than just a finishing touch: it’s a living expression of the same philosophy that drives biobased construction. While wood, bamboo and natural insulation create a healthy home from within, the green roof completes the cycle on the outside. It forms a breathing skin that works in harmony with the building, improving air quality, storing rainwater and enhancing biodiversity. Just like the materials beneath it, the roof is part of a closed natural system; renewable, regenerative and endlessly alive. In a biobased home, every layer matters, and the green roof is the layer that connects people directly back to nature.

We wanted to prove that beauty, comfort and circular design can coexist.

Circular design from the ground up

From the foundation upward, every component of these homes was chosen for longevity and renewability. Concrete is used only where necessary (in the foundation) while all other elements are made from CLT, bamboo and recyclable metals. Every joint uses dry connections, allowing materials to be reused or recycled in the future. The result: CO₂-negative homes that store more carbon than they emit during construction.

Crafted with care and detail

Architecturally, the homes are both sculptural and serene. The asymmetrical roofline gives them a distinct identity, while hidden gutters, elegant zinc detailing and vertical bamboo cladding lend a refined simplicity. Every line and junction has been designed with precision, from the slender window frames to the invisible fastenings in the façades. It’s craftsmanship with a purpose: long-lasting beauty that demands little maintenance.

Smart prefab, clean construction

Prefabrication was key to minimising waste and emissions on site. Each element was precision-engineered and assembled efficiently, ensuring a clean building process with minimal noise and disruption. Rainwater is buffered on the pitched green roof and around the property, where gravel strips and Sedum surfaces absorb runoff and reduce pressure on the drainage system. The homes achieve an A++++ energy label and are almost energy-neutral in daily use.

The meaning of Symbiose

“Symbiose” stands for connection; between people, nature and technology. These homes show that sustainability doesn’t mean compromise, but collaboration: wood, water, sun and greenery working in harmony to create comfort and balance. They embody the future of living. They are homes that give back more than they take.
