Temporary classrooms for schools: a fast, flexible solution for when you need space now

When a school needs extra space in a hurry whether for a building project, a bulge year, or an unexpected facilities issue the options on the table rarely feel good. Portacabins take time to organise, modular buildings require planning, and using the school hall disrupts everything else. There is a faster, more flexible alternative that schools across London and the South East are increasingly turning to: a marquee-based temporary classroom from Trafalgar Structures.

Why schools choose a marquee classroom

A marquee is not what most people picture when they hear ‘temporary classroom’. Modern marquee structures are insulated, secure, heated, and fully carpeted they are not a draughty event tent. They are custom-built to fit the available space on your school site, whether that is a courtyard, a corner of the playing field, or an area that wraps around an existing building.

The core advantages over other options are speed and flexibility. Most installations are completed within one to two days. We operate a mixed fleet of vehicles, not soley articulated lorries so there is no lorry manoeuvring across your playground, no damage to running tracks or football pitches, and far fewer health and safety complications on site.

Do temporary classrooms need planning permission?

This is the question we are asked most often, and the answer depends on how long the structure will be in place. For hire periods of 28 days or less, a temporary structure does not require planning permission. For longer-term hire which many schools opt for during building works or to manage sustained pupil number increases permitted development rights typically apply to educational premises, but we always recommend confirming with your local authority before proceeding.

We can advise on this as part of your initial enquiry, and we have worked with schools across London and the South East on both short and long-term installations.

How quickly can a classroom be ready?

In most cases, we can have a structure on site and ready to use within 24 to 48 hours of confirming the booking. For emergency situations such as a roof leak, a burst pipe, an unexpected facilities failure we understand that speed is everything. Get in touch and we will let you know what we can do.

A marquee vs a portacabin: the key differences

Portacabins are the most common alternative people consider. There are some important practical differences worth understanding before you decide:

  • Delivery: portacabins arrive on large articulated lorries and require a crane or forklift to position. Our marquees arrive in vehicles for the site and are assembled by hand.
  • Site access: lorries and lifting equipment require significant clear space and can cause ground damage. This is rarely practical on a busy school site.
  • Shape flexibility: portacabins are fixed units in fixed dimensions. Our marquees can be configured to almost any shape or footprint to make the most of your available space.
  • Carbon footprint: marquee structures have a significantly lower carbon footprint than portacabins, which aligns with the sustainability priorities of many schools and local authorities.

Recent example: Valentines High School

When Valentines High School in Ilford needed additional space quickly, Trafalgar Structures provided a temporary marquee structure that gave the school the breathing room it needed without disrupting the day-to-day operation of the site. The installation was completed rapidly, the structure was fully insulated and heated, and the school had a functional, comfortable space within days of getting in touch.

Frequently Asked Questions

Are marquee classrooms warm enough for use in winter?

Yes. Our structures are fully insulated and we install heating as standard for school hire. The internal temperature is controllable and consistent — students and staff are comfortable year-round.

Are temporary marquee classrooms safe?

Yes. All our structures are erected by trained, experienced teams and comply with the relevant health and safety standards. We are MUTA members and hold SafeContractor accreditation. Solid flooring is installed as standard, and security doors are fitted to all classroom structures.

How long can a temporary classroom stay in place?

Our structures can remain in place for as long as needed — from a few days to several years. Many of our school clients start with a short-term hire and extend as their needs evolve. We work around your academic calendar and remove the structure at the most convenient time.

Can the classroom be connected to the main school building?

Yes. We regularly build covered walkways and corridor connections between the main school building and the temporary structure, so students do not need to go outside to access it. This is something we discuss as part of every school enquiry.

Fantastic support to us
Trafalgar Structures have been a fantastic support to us since we reopened after lockdown. The provision of a high quality marquee to help facilitate our opening strategy meant we could cater for adult and child classes whilst following the required government guidance. The service and workmanship from the team was first class and the team were always happy to help out if any issues arose and amendments to the marquee were needed. I look forward to working with the team again and would fully recommend for any marquee needs

The Lid on the Lawn
‘The Lid on the Lawn’ installed by Trafalgar Structures enabled us to reopen safely after the July 2021 easing of the government guidelines, within 10 days we had a fully operational table service outdoor restaurant. Such has been the successful transformation of the outside space, we have kept the marquee for a longer term hire. The demand for outdoor dining and eventing has increased exponentially and the marquee has enabled us to confidentially offer weather proof ‘outdoor events’. This is now a permanent fixture with an additional full takeaway facility for visitors to the estate. Team Trafalgar are always on hand and have also reacted extremely quickly to the last minute nature of corporate event enquiries. Many thanks.

I cannot find fault in anything they did

We used Trafalgar Structures at the start of lock down. We were very fortunate to be able to remain fully working however, as everyone did, we had to make some major adaptions on our site to accommodate the 2m distancing. I came across Trafalgar Structures and I found them to be extremely helpful, knowledgeable and helpful. We had constant changes to the brief but that didn’t matter to James and his team, they were very accommodating and continued to be very helpful and help fulfil the works we required as well as give a lot of suggestions to make this work. The team that erected/ dismantled the marquee were extremely professional and friendly and helpful throughout the 2 days. I would highly recommend Trafalgar Structures and I would certainly use them again. I cannot find fault in anything they did. Thank you all so much for your help and guidance

Trafalgar Structures came to the rescue when the school needed additional outdoor teaching and testing facilities during the Covid pandemic. The cost of hire was extremely competitive and more than reasonable, particularly when you consider their services are much in demand. From the MD to the installers on the ground they were easy to deal with – nothing was too much trouble. Even last minute changes, and their after sales service was just as good. Its not every day you hire a marquee, but if I have to in the future, Trafalgar will be my first port of call. A huge thank you to James and the team!
