Bespoke Modular Buildings



Modular buildings are an excellent choice for commercial businesses, healthcare facilities, educational institutions, and organisations operating in many other sectors. Though we have a wide range of modular buildings available, you may be looking for something very specific in terms of size, configuration, style, fittings and branding, in which case we recommend having a chat with us about our bespoke design services. No matter what you need from your modular building, our specialists will design, manufacture, deliver and install it to your exact specifications. As well as saving you time, money and stress, you also gain the peace of mind that your modular building has been designed so that you can use it to its full potential right away.

Affordable solutions & investment


Due to them being highly affordable and requiring less foundation work than modular buildings, our portable buildings are popular with the construction industry and often chosen by other sectors as a temporary solution. However, many of our customers select portable buildings as a long-term investment thanks to their versatility and the option to relocate them as their premises develop.

As with our modular buildings, we provide a bespoke design service for portable buildings of all sizes, from small units to triple-storey arrangements. Anything you require to maximise productivity, efficiency, accessibility and adaptability can be factored in, so don’t be afraid to let us know your ideas and unleash your imagination.


When it comes to our bespoke design service, the sky’s the limit! You can choose the size of the building and number of storeys, its internal layouts, any particular fittings or fixtures, whether or not you’d like solar panels installing, what kind of overall aesthetic you envisage, your accessibility requirements, and even whether you’d like to have a vinyl wrap fitted to the exterior of the building to maximise brand awareness. We pride ourselves on providing a fully bespoke design service – simply get in touch and let us know what you have in mind.


Whether you need a bespoke portable building that can be moved around your site or a fully customised modular building that will extend and enhance your premises, we’re here to make it happen.
