05

Production

Your building is built from premium sustainable materials at our UK factory.

Each piece of steel is meticulously checked and accurately cut to match your personal specifications. Every component passes through quality control with CE markings before leaving the factory.

All of our products are manufactured in the United Kingdom.

06

Groundworks

First your groundworkers will prepare the foundations and base of your building. We typically install concrete slab foundations, which are more sustainable and built to last.

07

Installation

Our installation partners will typically install your building within 5-7 days, with minimal disruption to you.

Due to the modular structure of our buildings, we can still complete installations if there is limited or no external access to your garden.

Your building is now ready to use straight away!
