What are the differences between portable, modular and jackleg buildings?

What are the differences between portable, modular and jackleg buildings?

What are Portable Buildings?

Simply put, portable buildings are a self-contained, moveable building. Our portable buildings are designed and built by our experienced team, tailor-made to suit the needs of your business. This means they arrive to you ready made, meaning less on-site time and less disruption.

Our portable buildings are hugely flexible – and by that we don’t mean they aren’t sturdy! They are! We mean that you can choose to alter them later down the line, so if you’re short on time or on budget, we can always expand on them in the future. This creates a building that can grow with your business in a cost-effective way, something rarely seen in traditional builds.

What are Modular Buildings?

Modular buildings arrive on site in units and are then secured together to create your finished build. This means that there is more time spent building on-site when compared to portable buildings that arrive ready made, however, it’s still a fraction of the time when compared to a traditional build.

We’re hugely proud of our modular buildings and can accommodate builds to suit a range of industries, from modular builds for the educational sector to modular buildings perfect for the NHS. They are all built in our factory to your specification, allowing you to choose from our extensive building finishes to get exactly what you what. Our flexible and cost-effective modular buildings offer an unparalleled level of convenience and style, making them an excellent choice for many businesses across the UK.

What are Jackleg Buildings?

Jackleg cabins are named after the metal legs which are attached to the bottom of the cabins. These legs give the cabins the flexibility to be placed on uneven surfaces or to be stacked on top of each to create multi storey units. We’ve worked hard to achieve a top-quality, comfortable yet convenient workspace, and what’s more, they’re constructed off-site, resulting in a building that’s ready to use as soon as it arrives! It doesn’t get much more efficient than that!

With jackleg cabins, you can add or upgrade modules as and when it suits, this allows you to have a building that can grow in line with your business, giving you incredible flexibility and peace of mind.
