Lime Academy Forest Approach
Project Brief
Lime Academy Forest Approach required a temporary classroom building to provide additional teaching space for new students joining the school. The requirement arose at short notice, meaning the building had to be delivered and installed within a very tight programme while the school remained fully operational. A modular double classroom block was selected to allow rapid deployment without the delays associated with traditional construction. The building had to include two fullsize classrooms, WC facilities, storage areas, and all necessary service connections, while remaining compliant with current building regulations and education standards. The completed project provided a fully functional teaching environment delivered in a short timeframe, demonstrating the effectiveness of modular hire buildings when additional space is required quickly.
“Thank you for all of the hard work involved in getting the classrooms on site and up and running on such a very tight schedule. It has truly been a pleasure.”

The Main Features
Outside
The building was supplied as a modular double classroom measuring approximately 8.4m by 19.6m. This provided two full-size teaching spaces within a compact footprint while allowing for rapid installation on site.
The external walls were finished in plastisol-coated steel cladding, offering a durable and weather-resistant surface that requires minimal maintenance and is well suited for long-term hire use.
A rubberised EPDM roof system was installed to ensure reliable waterproofing and a long service life, protecting the building from weather exposure throughout the hire period.
High-performance uPVC windows were fitted to provide natural light and ventilation, while black rainwater goods were installed to safely discharge water into the site drainage system.
Access to the building was provided via external steps and a Part M compliant access ramp, ensuring safe and convenient entry for all users. The ramp enabled inclusive access for students, staff, and visitors while maintaining full compliance with current accessibility regulations.
Inside
The layout included two modern teaching classrooms, each measuring 64m² and designed to meet education standards. These spaces were bright, flexible, and suitable for a wide range of subjects.
The building incorporated both standard WC facilities and accessible WC rooms, which were positioned centrally to allow convenient access from both classrooms.
Inclusive hygiene facilities were also provided, including a fully equipped hygiene room and accessible WCs. These ensured dignified, compliant provision tailored to pupils with additional learning needs.
Internal storage rooms and a central lobby enhanced the building’s functionality, allowing equipment to be stored safely while keeping teaching areas clear and organised.
Internal partitions and ceilings were constructed using fire-rated plasterboard systems, ensuring compliance with current safety regulations and contributing to a secure learning environment.
Durable floor and wall finishes were used throughout, with carpet in the classrooms and vinyl flooring in circulation and WC areas, providing a hard-wearing and easy-to-maintain solution suitable for daily school use.
Challenges & how we overcame them
The school required additional teaching space within a very short timescale due to an increase in pupil numbers. From initial instruction to completion, the available programme was approximately five weeks, leaving little margin for delays. To achieve this, the team used readyto-deploy hire buildings and carefully coordinated all stages of manufacture, delivery, groundwork, and installation to ensure the building could be handed over on time. Additional working hours and weekend labour were required to maintain progress.
The programme was further compressed due to delays in the client confirming the final order. During this period, the planned completion date had to be revised, which reduced the available construction window. Once approval was received, the team had to react quickly by rescheduling deliveries, arranging labour at short notice, and coordinating subcontractors to ensure the revised programme could still be achieved without affecting the school’s need for the building.
The installation location could only be reached by passing delivery wagons across existing school grounds. To allow safe access for heavy vehicles and the installation crane, a temporary roadway had to be constructed. This ensured the ground surface was protected and that vehicles could reach the foundations without causing damage to playground areas or landscaping. Careful planning was required to ensure the roadway could support the weight of transport vehicles and lifting equipment
The site contained existing underground services which restricted where foundations could be installed. A survey was carried out before works began, and temporary pad foundations were positioned to avoid conflicts with buried pipes and cables. This required adjustments to the original foundation layout while still maintaining the correct structural support for the modular building. Accuracy at this stage was critical to ensure the building could be installed without delays.
Connecting the new classroom block to the existing drainage system proved difficult due to the distance from the nearest suitable connection point. The solution was to link the building into an existing pumped drainage system serving another temporary classroom on site. This required additional pipework, careful coordination with existing services, and testing to ensure the system operated correctly once the building was in use.
As the work took place within a live school environment, strict safety procedures had to be followed at all times. All site personnel required DBS clearance before being allowed to work on site, and deliveries had to be planned around school hours to minimise risk to students and staff. Temporary fencing, controlled access routes, and close coordination with the school ensured the project could be completed safely without interrupting normal daily activities
The Results
Rapid Response, Reliable Results
The Lime Academy Forest Approach classroom block provided a fast and reliable solution to the school’s need for additional teaching space. Delivered within approximately five weeks from instruction to completion, the project demonstrated how modular hire buildings can be deployed quickly without compromising quality.
Despite restricted access, drainage challenges, and a shortened programme, the building was installed safely and within budget. The finished structure provided two bright classrooms, integrated WC facilities, and durable finishes suitable for continuous daily use.
The project allowed the school to accommodate new students without disruption to its timetable, providing a comfortable and fully compliant learning environment. The flexibility of the modular system also means the building can be relocated or reused in the future if required.
This project highlights the advantages of modular construction, showing how ready-to-go hire buildings can provide high-quality teaching space at very short notice.
