A purpose-built wellness retreat, crafted for movement, restoration, and luxury outdoor living.
The Gym, Spa & Sauna Garden Cube is a striking L-shaped configuration that brings the essence of a boutique fitness and wellness studio to your own garden. Blending natural materials with architectural precision, this multi-room cube delivers an immersive health and relaxation experience — all within a thoughtfully zoned 4x6m footprint.
Whether you're beginning your day with movement or ending it in quiet recovery, this space supports your routine with elegance and intention.
A Fully Equipped Private Gym (4m x 3m)
Framed by a full-length sliding glass wall, the gym room offers a light-filled training environment that opens directly to your garden. Whether you're lifting, stretching, or doing cardio, the clean lines and natural timber surroundings help create a calm, focused energy for movement.
Open-Air Spa Area (3m x 3m)
On the opposite wing of the cube, the spa area is open on two sides, allowing in fresh air and unfiltered views of your natural surroundings. Ideal for housing a hot tub or plunge pool, this space offers the serenity of a private retreat while maintaining a visual connection to nature.
4-Person Sauna with Harvia Wood Stove (2m x 3m)
Centrally positioned for balance and accessibility, the sauna room is finished with natural wood interiors, a large glass door, and a window for soft, ambient lighting. Heated by a premium Harvia wood-burning stove, it offers an authentic sauna experience — ideal for deep relaxation and post-workout recovery.
Three Zones, One Seamless Experience
Each section of this L-shaped cube has been purposefully designed to serve a different function — movement, restoration, and heat therapy — while still feeling like one unified, luxurious environment. Natural timber, soft lighting, and intelligent layout choices keep the space feeling both modern and grounded.

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.
