Introducing the ARC by Green Unit
We call our modular buildings ‘The ARC’. We design our ARC buildings with our uniquely curved structure that mimics forms found in nature, which we combine with a naturally light-filled and airy design to create a space that’s incredibly calming and uplifting.
Our ARC building design uses sustainable materials and focuses on high levels of insulation and airtightness to ensure a highly efficient, green building.


Highly adaptable, bespoke for you
The unique curved modular structure is common across all our ARC buildings, and we design and build every building to suit individual project requirements.
What our customers say
We have been very happy with the feedback from guests in Bumble Barn, and really enjoyed entertaining our friends and family in there too – it has such a lovely calming, tranquil to it, cocooned within the oval shape, with amazing views over the fields, and so warm and cosy on chilly days. It truly is ultra luxurious glamping, surrounded by nature, the kestrel perched on the planter, the hares hopping round the window, birds singing and soaring, deer, badgers and foxes wandering by.
