Dan Ashley looks at how modular building techniques were successfully used in a specialist SEN setting.
Schools and local authorities are increasingly required to expand SEN capacity quickly, while ensuring that new learning environments are safe, inclusive and tailored to complex needs. Modular construction is a practical solution, offering speed, flexibility and high standards of design that can directly fulfill the requirements of SEN settings.
A recent sixth-form expansion project at Willow Dene School in Greenwich provides a good illustration of how modular buildings can be successfully used to meet these requirements. The school required a new facility to support students aged 15 and over, with a strong focus on accessibility, safety and staff supervision. The project was delivered as part of a wider local authority initiative to increase SEN provision and respond to growing demand in the borough. Modular construction allowed buildings to be designed around the specific needs of SEN students, rather than forcing users to adapt to standard layouts. The new sixth-form building was designed to include specialist features including secure, staff-controlled access points, clearly defined circulation routes, and calm internal environments that help reduce anxiety and sensory overload.
Accessibility was a central consideration. A lift was incorporated to provide step-free access to first-floor classrooms and breakout spaces, ensuring that wheelchair users and those with reduced mobility could move freely throughout the building. A dedicated hygiene and changing room was also provided on the ground floor, offering a dignified and practical space for students who require additional personal care during the school day. Alongside teaching spaces, the building includes breakout areas, a reception, staff facilities and well-designed toilets. These elements help support the day-to-day operation of the school while creating a structured yet welcoming environment for learners with varying levels of need.
Many SEN schools operate on tight sites, often in established residential areas. Modular construction is particularly well suited to these conditions. Offsite manufacture allows the majority of construction work to be completed in factory-controlled conditions, with modules delivered and installed on site in a short timeframe. For the Willow Dene project, the building was positioned in a narrow area between an existing school building and a car park. The modular approach enabled precise installation with minimal disruption to the surrounding estate. Installation can often be scheduled during school holidays, reducing the impact on pupils, staff and neighbouring communities.
Successful SEN projects rely on close collaboration between local authorities, education professionals and design teams. Early engagement ensures that buildings respond not only to regulatory requirements but also to the lived experience of students and staff. In the Willow Dene project, the planning process involved detailed consultation with school leadership and inclusion specialists to ensure that layouts, circulation and facilities aligned with the school’s ethos and operational needs. Inclusive design principles were embedded throughout, helping to ensure that the finished building supports dignity, independence and wellbeing. Modular construction can also support environmental objectives through reduced waste, efficient material use and improved building performance. Features such as green roofs and mechanical ventilation with heat recovery were incorporated into the Willow Dene design, supporting energy efficiency and internal comfort. The completed sixth-form building demonstrates how modular construction can deliver high-quality, inclusive environments for specialist education. By combining thoughtful design, accessibility, and efficient delivery, modular solutions can help schools and local authorities respond quickly to rising SEN demand without compromising on quality or care.
