Built for the Outdoors
A Centrepiece for Your Outdoor Space
The Weathered Grey exterior cladding gives the largest C2 model a commanding, contemporary presence — built to become a permanent, considered feature in your garden rather than simply placed in it. The bold grey tone works naturally with modern architecture, stone, and landscaping.
The extended roof overhang provides meaningful protection from rain and the elements, improving both the longevity of the structure and its energy efficiency — while the lockable door and protective cover keep everything secure between sessions.
Presence at Maximum Scale

Protective safety guard as standard
Dual thermostatic regulation for stable multi-user heat
