The process is simple – just contact us for a FREE consultation and we’ll take it from there.


We take your brief and understand all of your requirements as part of your project.

This includes aesthetic and environmental factors, as well as how you will use the building to ensure we can maximise its potential.

Our process is focused on finding a right solution for you, not just simply providing the best fit.


Design is an important stage. Where many will simply group rectangular buildings together, we’ll look at a modular building which maximises efficiency and capabilities.

We have a range of materials to make sure it creates an architectural solution which is right for you.

This way, the design is adaptable and works for you.


The way that we construct our buildings allows for efficient completion with a quick turnaround.

Whether it’s to start a major construction or rail project, install a new classroom within the school holidays, or a new changing room ahead of the new season – we will build it to your timescales.


We deliver UK-wide and provide a fast installation service to ensure you are up and running as soon as possible.

Our installation team works with you so we leave you with a fully-functional building as outlined in the brief.

We’ll even be able to come and take it down for you if you’re looking for a temporary solution.
