Rebound Therapy Garden Room for Jason

We recently completed this bespoke rebound therapy garden room for Jason, creating a practical, welcoming space designed around specialist wellbeing and movement sessions. The room features a sunken trampoline, allowing safe and accessible rebound therapy in a purpose-built environment, with plenty of clear floor space around it for support and supervision.

Externally, the garden room is finished in modern grey composite cladding for a smart, low-maintenance look, complemented by a durable EPDM rubber roof. Full-width French doors open out onto the patio area, bringing in natural light and providing easy access for users, families and therapists. This project is a great example of how a bespoke garden room can be designed for far more than a home office or gym — creating a dedicated space that genuinely supports health, therapy and everyday life.
