The original 3rdSpace design provides exceptional quality spaces, perfect for a range of uses, from garden rooms, to offices and studios. Enjoy uninterrupted views with full-height double glazed windows and a simple, beautiful interior space made with premium birch plywood. Cladding options include black-stained timber or natural larch.

We can help you configure your ideal layout based on fixed model sizes, and because the system is totally modular your building can be dismantled and relocated if ever needed. Modular also means more flexibility, particularly well-suited to sites with challenging access. Planning Permission is not required in many cases.
