Our Selection of Modular Buildings in Southampton

While our portable buildings are delivered and installed as a single unit, modular buildings will be made from several pieces, allowing a far larger range of sizes and shapes to be constructed. Modular buildings offer everything you would expect from a masonry construction, with power, water, and insulation. All of our products can be carefully installed in Southampton by a member of our team.

Selling both new and used modular buildings allows us to cater to a huge range of clients and budgets while maintaining our reputation for quality, as evidenced by our many glowing reviews on Trustpilot. Our team is friendly and upfront, offering clear and helpful advice to all customers. Whether looking to buy a modular office for a building site, or to rent a sales room for the summer, we offer superior products at competitive prices.

Industry experience

We started in the industry as sellers of quality used buildings, with a selection of modular and portable options. The knowledge we gained from this was crucial when we came to manufacture our own buildings, which we produce entirely on-site, including frames.

We prioritise the highest levels of quality, through both our expert design processes, and the technological investments we have made such as our CNC facade machine, which produces attractive bespoke panelling. We truly believe in the quality of our products, which are designed around long-term performance.
