Modular Buildings for Sale in Southampton

If you’re looking for a durable and fully featured modular building in Southampton, whether it’s for an office, a sales unit, or more, we can provide you with everything you need. We sell new modular buildings produced from the ground up by our expert team, alongside carefully selected used buildings, all of which can be delivered and installed in Southampton.

Our 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.

High-Quality Buildings Manufactured In-House

Straightforward, Reliable Customer Support

Modern, Practical & Affordable Designs

New Modular Buildings

Our new modular buildings are produced at our Chichester facility, including the structural frames. This gives full control over materials, strength, and finish. Designs are available for offices, sales and marketing suites, welfare space, and general-purpose accommodation.

Typical lead times are 6–8 weeks from order to completion. Once manufactured, buildings are delivered and installed on your Southampton site, with minimal disruption.

Bespoke Modular Buildings

Because our buildings are manufactured in-house, we can also produce bespoke modular units to a specific brief.

Size, internal layout, external appearance, and features such as larger glazing or anti-vandal walls can all be tailored to your requirements. This is ideal where a standard layout does not fit the site or intended use.

Used Modular Buildings

For projects working to a tighter budget, we supply used modular buildings that have been selected and refurbished based on frame condition, structure, and overall potential.

Used units provide the same core functionality as a new modular building at a lower cost, making them suitable for offices, welfare facilities, storage, and temporary accommodation.

Hire a Modular Building in Southampton

If you need a modular building for a limited period, units are also available to hire in Southampton through our sister company, Offsite Hire.

Hiring is often a practical option for temporary offices on construction projects, short-term sales or marketing suites, or seasonal facilities. Buildings are delivered and installed on site, then removed at the end of the hire period.
