Modular eco classrooms, studios, spas and community buildings

The spacious, calming proportions of the ARC make it perfectly suited to the learning environment and for group activities. It can be used as a self-contained, purpose-built unit or as an annex to an existing school. Its harmonious contours and modular design make it ideal for multiple uses from yoga studios and spas, to music rooms and studios for art or drama.

Prefabricated, purpose built rooms for schools and community use

We help you design the layout you require, in sound-insulated sections that can be reconfigured if necessary. The ARC can be sited almost anywhere, with minimal foundations, and can be extended or even re-located. We can also provide bespoke craftsman-built furniture and fittings. Contact us for more information.

Warm in winter, cool in summer

Outstanding energy efficiency means the ARC is always at the optimum temperature, providing year-round comfort and keeping running costs low. Pollen-filtered air keeps the atmosphere clean and healthy.    

Furniture options

Built-in storage, desks, tables and chairs can all be built by our in-house team of craftsmen, working locally in Oxfordshire. We can also design and make bespoke reception areas, noticeboards and other one-off pieces to provide a truly unique venue.

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

Speed of installation

Pre-made, pre plumbed, buildings are quick to install with no cost escalation

Lengthy preparation, first , second and finish fixing stages with cost escalation risk

Energy performance

Highly insulated, climate controlled with air heat exchanger and triple glazing

At risk of energy loss by air leakage and cold-bridging through walls and widows


Timber construction, sheep’s wool and green roof produce negative carbon footprint

Materials and production processes require heat energy, heavy transport, produce CO2

Design configuration and reconfiguration

Modular design allows unique individual configuration and low-cost reconfiguration choices

Bespoke design and reconfiguration time-consuming and costly


Pre-manufacture fixes total building cost to between £1K and £2K per square metre

Final costs of traditional buildings often rise to £2K - £3K per square metre
