How long does a portacabin last?

With routine maintenance, a portacabin will typically last around 20–50 years, and is built for durability even in demanding environments like construction sites.

Can portacabins be insulated for year-round use?

Yes. Portacabins can be insulated for all-season use; MPB states their cabins are insulated as standard in the walls, floors and roofs to help keep internal temperatures stable across seasons.

Can you stack portacabins?

Most portacabins are designed so they can be stacked to create multi-level layouts, with robust steel frames intended to maintain structural integrity under load.

Do you need planning permission for a portacabin?

It depends on factors like how long it will be on site and its size. MPB notes that if it will be onsite for less than 28 days and the floorspace doesn’t exceed 100 m², planning permission may not be needed; if unsure, check with your local planning authority.

How much does a portacabin cost?

Costs vary widely depending on size and specification. Larger or higher-spec units generally cost more than smaller or basic cabins; MPB advises contacting them for a free quote.

How Much Do Modular Buildings Cost in the UK? (2026 Guide)

If you’re thinking of buying a modular building for your business or industry, then the cost will likely be the first thing you’ll consider. In this guide, our experts will detail how much modular buildings cost, and the different factors that affect the price such as the size, features and services required.

What is the Average Modular Building Cost in the UK?

Modular buildings in the UK cost on average anywhere from £25,000 and £200,000+. The price will come down to the size of the building, including how many bays are included, as well as final finishing choices and bespoke features. Here’s a general price guide for modular buildings based on the building type:

Office buildings – New modular office buildings start from around £50,000 + VAT for 2 bay designs, with larger offices increasing to prices of around £110,000+. Refurbished modular offices are often 60-70% of the cost of a newly manufactured building.
Marketing suites – These can start from £30,000 and rise to £500,000 + VAT with larger bespoke designs.
Leisure and gym buildings – Typically larger in size and featuring premium interior finishes, these costs start from around £75,000 to £115,000+.
Healthcare buildings – Facilities can range from £80,000 to £500,000 depending on the complexity of the build and the included medical equipment.
Canteens – Portable canteens can start from £15,000

Modular Building Costs vs Traditional Construction

While these numbers may seem like quite a lot at first glance, the cost of modular buildings compared to traditional construction is far lower. This is down to several reasons, including the construction methods, predictable manufacturing processes, simpler designs and lower labour expenses.

Fast construction – Modules are built while groundworks are prepared for the final installation, streamlining project timelines compared to traditional construction which can only start once the site is fully prepared.
Minimised material waste – Modules are built in a controlled factory environment which allows for exact material usage and the ability to recycle materials, cutting down on costs associated with construction waste.
Simple designs – Simple doesn’t mean bare bones. Modular buildings follow standardised designs and repeatable processes that provide financial predictability.
Minimal disruption – Being made off-site in controlled environments, modular construction benefits from fewer delays due to adverse weather, meaning projects run on schedule and within budget.
Reusable and relocatable – Modular buildings can be relocated to different sites and easily adapted, making them a worthwhile investment for both short-term and more permanent use.

What Factors Affect the Cost of a Modular Building?

Modular building costs can fluctuate based on several key factors, including the size, interior features, materials and additional services like delivery, groundworks and installation.

Building Size and Layout

It sounds obvious because it is; the larger the modular building is and the more complex the layout will result in a higher price. The larger the build, the more materials will be used, transport becomes more expensive, and lead times will increase, all adding onto the overall cost.

Bespoke Features

Custom designs will increase the cost of a modular building because of the extra design and manufacturing requirements. If you choose to have additional features such as kitchenettes, toilets or partitions, the overall build cost will be higher.

Materials and Construction Choices

Modular buildings are made from a range of materials, some more premium than others. Choosing to add exterior cladding will increase the final price, even for smaller two or three-bay builds. Often this is worth the investment as it offers better insulation and aesthetics while being low-maintenance.

Delivery and Installation

Our modular building costs include the price of the build plus VAT, but not the additional costs for groundworks and delivery and installation. It’s important to consider all service costs, and we will provide quotations for every new project or refurbishment.

Extra Facilities

You may decide further down the line that you’ll want extra facilities alongside your modular building, with common additions including portable toilet blocks and portable changing rooms, or it could be a separate modular building all together, such as a site canteen. Facilities like these are great add-ons for modular offices and gym buildings, but they will require more plumbing and electrical work to be completed, further increasing overall costs.

Are There Any Other Ways to Reduce the Cost?

Buying modular buildings brand new isn’t the only option. In fact, you don’t necessarily have to buy a building outright, as there are several other options to consider if there are budget constraints.

Consider Buying a Used Temporary Building

If you want to buy outright but your budget doesn’t stretch to the figures listed above, consider purchasing a used temporary building. A used structure is already pre-built, so you’ll save even more time on installation, and the refurbishment of the building restores it for full use, no matter the application. The overall price of a used modular building that’s been refurbished is far less than designing and manufacturing a brand-new one.

Short-Term Modular Building Rentals

For short-term use, you can hire a modular building at competitive prices with MPB. Pay only for what you need, when you need it when you hire, which is ideal for when you need a temporary building at short notice or for a project with a confirmed end date.

How much does a modular building cost? It all depends on whether it’s a new build, a refurbished unit, whether bespoke features are included, the choice of purchasing or hiring, as well as the overall size and complexity of the design. However, modular buildings are far more cost-effective than traditional builds, when you need extra facilities fast on a temporary or permanent basis.
