About Us


Who Are Green Modular?

We are part of the Stillwater Group – a family run business established since 1985 employing over 100 people across 3 sites. We are proud of our heritage and understand our clients want to be reassured that their building will be made to a high specification and completed on time.

All of our modular buildings for schools and commercial outdoor buildings use fabrication manufactured within the group. This means we are in total control over quality and the supply chain. Located in Harpenden and Watford in Hertfordshire, our factories manufacture cutting edge windows, doors and timber.

Our passion is for quality and innovation. We always make it our aim to produce materials that are built to last and are sustainable.

Focused on education

We fully understand how vital a positive environment is for teaching and learning, and we believe that our mobile classrooms provide the ideal environment for nurturing your students. We pride ourselves on providing a bespoke service for the education sector and meeting the requirements of both students, teachers and the school as a whole. Our project managers will work closely with you to create sustainable and practical solutions to your education needs.

Sustainable fabric first design

Whilst our modular buildings for schools and busineses look great, they are also robust and comply with the relevant building regulations. We take a Fabric First approach to our constructions to ensure that the building materials and designs created give the best performance. Our creative team understand what’s needed for a successful design of outdoor commercial buildings and eco classrooms, in order to offer an outdoor space solution that will not only be practical in terms of layout and structure, but will be built to last.

Everywhere is Green

We also have a sister company Green Studios that provide garden rooms to residential properties. We apply the same quality materials and processes to our manufacturing and design, but for the home. Creating a lifestyle that allows you to work from your garden room, enjoy a hobby, or use it as a guest room. The choices are endless!
