We are pleased to share one of our largest and most unique projects, which was recently completed.
The 15 × 7 metre fully insulated timber building was designed from the very beginning around the client’s wishes and lifestyle. With approximately 75 m² of interior space, it includes everything needed for a private wellness centre: a home gym, massage room, SPA area, sauna with a 30 m² terrace, as well as several smaller practical spaces.
💪🏻 One of the central features of the building is the spacious home gym, with two high-quality wooden bi-fold doors, each approximately 3 metres wide, and two tall windows. When fully opened, the bi-fold doors connect the gym directly with the garden, creating a seamless indoor-outdoor space. This makes it possible to work out in the fresh air, enjoy plenty of natural light and stay surrounded by greenery.
💦 For relaxation, the building includes a separate massage room, SPA area and private sauna opening directly onto the covered terrace. Nordic spruce has been used for the sauna interior, with Thermo Aspen benches and backrest. At the heart of the sauna is a Harvia Cilindro electric heater with approximately 100 kg of sauna stones.
🔩 The building has been carefully designed for year-round use. The strong structure features 70 mm wall beams and 28 mm floorboards. The roof and floor are insulated with Recticel PIR boards, while the external walls feature mineral wool and a wind barrier membrane. Electrical and climate-control cables and connections were integrated into the structure during construction. The exterior is finished with premium Thermo Wood cladding, treated with two coats of high-quality wood oil.
This project is a great example of what can be achieved with a fully bespoke timber building. The finished building is much more than a traditional garden house. It is a private wellness centre combining exercise, massage, SPA, sauna and outdoor relaxation – all conveniently located in the comfort of the client’s own garden.
Who’s already looking forward to seeing the house fully furnished? We hope to share those photos with you soon!
