Why Modular?

The question is, Why Not?

We are not a one size fits all supplier, we are a true ground up manufacturer.

Offsite construction is a growing trend, with efficiency, sustainability and less disruption to people and businesses nearby being a few reasons, it's easy to see why.


The building arrives on your site and is installed and made secure in just 1 day. In buildings that have internal fittings, the following 1 to 2 weeks are used to complete the internal fittings ready to be handed over to you. This reduces the time spent on the site, removes issues around site security during construction, and lessens the impact on the surrounding areas.

The site works are carried out in the weeks before the building arrives by your principal contractor. We work closely with whoever is appointed to ensure service connections are in place and base works are completed to the building’s requirements. This is often less than would be needed for a traditional building due to the construction technique we use.

Over all our system provides a faster build with less site impact, reduced security issues, and provides a more robust product than many can claim.

Our modular system allows for a wide range of possibilities with regards to layout, size, and finish. We do not repurpose containers, we build your building from scratch to a superior specification.

You can supply a hard copy or digital drawings of your proposed design to our sales team if you have them or alternatively contact us and we will do the design work for you. Our design team will take your initial design requirements and provide a written specification, drawing, and costing for the project.

What Our Customers Say

Cleveland Sitesafe have provided Fairburn Ings Nature Reserve with three anti-vandal steel hides built to our specification. They have proved to be very successful and stood up to attempted vandalism with little damage, they are also cheaper than similar sized wooden structures and a lot easier to keep clean and maintain.

We have had many Sitesafe products over a number of years. We find Sitesafe helpful with the initial design through to installation and their products have proved to be robust.

The addition of the two new buildings has significantly improved the grounds operation area, allowing us to fully to comply with our health and safety obligations. As well as meeting the legal side, the buildings offer first class garage accommodation to high value kit which would otherwise deteriorate quickly sitting outside.

Since we opened the new visitor centre at Potteric Carr we have seen a significant increase in visitor numbers, people are amazed to hear the story of how the building was constructed and  also our staff  and volunteers love their new working environment.  Working with Joe  and his colleagues was a real pleasure and through practical and realistic discussions around project design and procurement, we were able to meet both  our budget and open on time.

I would definately recommend Cleveland Sitesafe Ltd and they would be the first port of call for any future requirements."
