Portable Cabin Sizes and Layouts

The right portable cabin size depends on what you need to fit inside and how the space will be used on a daily basis. Rather than choosing based on dimensions alone, it’s worth thinking about the number of people using the cabin and the facilities, furniture and equipment they’ll need. 

For an office, this might mean allowing enough room for desks, storage, meeting areas and comfortable circulation. Canteens, changing rooms and welfare cabins may need space for kitchens, toilets, lockers or separate areas, while classrooms need to accommodate pupils, furniture, storage and teaching activities. Equipment, counters and internal partitions can also reduce the amount of usable floor space available. 

If you’re unsure which size will work best, speak to one of our team about your intended use, number of occupants, available site space and required facilities. We’ll help you choose a cabin with a practical layout for your exact needs. 

Our Process

Step 1: Tell Us What You Need

Start with a discovery call, where we’ll discuss the required use, size and layout of the cabin, as well as discuss your budget and when you need it installed.

Step 2: Choose Your Size and Layout

Based on your requirements, we’ll provide several options on the ideal size and layout for your portable cabin, along with custom options for doors, windows and other core features.

Step 3: Review Your Drawing and Quote

We provide a 2D drawing layout and quotation for your chosen portable cabin fast. We can often do this the same day of your enquiry and discovery call. If not, you’ll receive it the following day without delay.

Step 4: Your Cabin Is Manufactured

With your portable cabin design confirmed, we get to work manufacturing it to order in our UK-based facilities, with all work backed by official certification and a full warranty for your peace of mind.

Step 5: Delivery to Your Site

Delivery is then arranged to your site, no matter where it is in the UK. Where required, we will check for access beforehand to ensure a safe and streamlined delivery. Our team then install your portable cabin with everything fitted, so it’s ready to use straight away. See how our portable cabins are delivered across the UK for more detail.

FAQs

What are portable cabins?

Portable cabins are practical, flexible spaces that can be used for a range of purposes, including offices, classrooms, canteens, welfare facilities and other site accommodation. The size and internal layout can be chosen around the number of occupants, furniture, storage, equipment and facilities required.

How much do portable cabins cost?

The cost of a portable cabin can vary depending on the requirements of the project. Factors such as the cabin size, intended use, internal layout and facilities required should all be considered. As every portable cabin will be bespoke and made to order, each quotation will be different. Discuss your specification with Flex for an accurate and completely free quotation.

How long does a portable cabin take to deliver?

Delivery times can vary depending on the cabin required, its specification and the delivery location. If you are working towards a particular date, speak to Flex as early as possible so we can confirm availability and provide a delivery timeframe based on your requirements.

Can portable cabins be customised?

Yes. The layout of a portable cabin can be planned around how the space needs to work, including requirements for workstations, storage, separate areas and facilities. We offer fully custom portable cabins for sale, from the layout and door positions to the colour scheme and interior features.

Are portable cabins insulated?

We include insulation as standard with all portable cabins we manufacture in the UK. Walls, floors and the roof will be fully insulated with thermal foil and fibre glass insulation, helping to provide comfortable temperatures and minimise heat loss.

What access is needed to deliver a portable cabin?

The access required will depend on the cabin, the site and how it will be positioned on delivery. Before delivery, discuss your available site space and access with our team so we can confirm what is needed and identify any potential delivery restrictions in advance.

Do you deliver portable cabins nationwide?

Yes. Flex Modular Buildings offers nationwide delivery of portable cabins. We cover England, Scotland, Wales and Northern Ireland and even areas like the Isle of Man.
