Our Cubes
One Structure. Endless Possibilities.
Our cubes are the foundation of a new era in luxury modular construction — a truly versatile exo-structure that can be configured for nearly any use. Whether it’s a bespoke glamping cube, an at-home wellness suite with a sauna, a café kiosk, or a private garden office, our modular cubes adapt to your vision with ease. Built with both residential and commercial applications in mind, the only real limitation is the space you have — and even that can be solved with smart layout design.
Our cubes range in size from compact 4m² setups to expansive 100m², fully functional single-storey spaces. This flexibility allows us to meet a wide variety of lifestyle and business needs — from private retreats to full-scale communal spaces or resort layouts.
Built to Last, Designed to Impress
Each cube is engineered with a premium-grade spruce frame and a solid insulated floor and roof system, anchored by four robust support columns. The construction features 50mm stone wool insulation for excellent thermal performance, fire resistance, acoustic comfort, and long-term durability — making it equally suited to alpine climates or urban gardens.
The floorboards are crafted from 146 x 28 mm timber, creating a strong, resilient base that feels solid underfoot. The walls are a 75mm thick insulated sandwich of spruce and stone wool, giving the cube warmth, quiet, and comfort all year round. A timber glass wall and high-performance sliding door system from Reynaers provide both natural light and accessibility, while enhancing the aesthetic appeal of your space.
Every element — from the panels to the paint — has been designed with energy efficiency, durability, and style in mind.
