Eco modular classrooms - schools, colleges and universities

Commission a series of self-contained ARC eco-classrooms or a new eco-building to an existing educational facility with a connecting glazed link, perfect for any school, college or university. The ARC is a calm and inspiring space which is highly conducive to learning.

Year-round optimum temperature whatever the weather

Unlike many self-contained outbuildings the ARC, with its heating options, including underfloor, in-wall and ducted heating and ventilation systems, offers year-round comfort for optimum working and learning environments. Add to the ARC the optional pollen-filtered air systems and you can create a cleaner and healthier environment to promote productivity and inspire creativity.

Solve learning space problems quickly with our modular units

Whether you are looking for an eco-classroom, green educational space, reception area, staff room or other ultra-low carbon educational spaces, the ARC can be designed, built and delivered to site fully operational with all electrics, plumbing, flooring, tiling and decorating already in place.

Built-in storage and smart systems

Our eco-classrooms and buildings can be supplied with built-in storage. Desks, chairs, reception areas and boardroom tables can also be designed and made by our in-house team of cabinet makers. We can also supply state-of-the-art smart systems to control temperature and air quality and operate media, windows, blinds, gates, locks, CCTV and other appliances.

Green Unit buildings

Traditional buildings

Planning permission

Classed as permanent or temporary where permanent planning consent is impossible

Full planning consent usually required for permanent buildings

Foundation type

Lightweight building on helical piles requires minimal ground preparation and disruption

Soil removal, engineering and concrete pour usually costly, time consuming and disruptive
