Compact Footprint, Complete Living

The core configuration is designed as a fully equipped residential annexe. The main living module integrates a bedroom area, compact kitchen, and bathroom within a balanced open-plan arrangement. Optional configurations allow for alternative uses such as a wellness-focused layout or a dedicated workspace module, providing flexibility depending on the intended purpose of the annexe.

The modular structure of Celtic Mini is one of its key strengths. Individual sections are precision manufactured off-site using cross-laminated timber panels, ensuring structural stability, thermal efficiency, and long-term durability. This approach allows the annexe to be adapted for independent living, guest accommodation, home working, or multi-generational family use while maintaining a refined residential standard.
