Energy-efficient eco-buildings

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.

Unique modular design

Highly adaptable, bespoke for you

Our modular design and offsite build process ensures that we deliver high-quality eco-buildings in a quick yet bespoke way for every client.

The unique curved modular structure is common across all our ARC buildings, and we design and build every building to suit individual project requirements.
