Modular SEND, SEN & SEMH Classrooms
Schools rarely need more SEND provision in the abstract — they need a room for a named group of pupils, usually for September. A modular building adds that provision on your own site, configured around the rooms you actually need: a teaching space, smaller intervention rooms, somewhere calm to withdraw to, accessible washroom provision and a base for staff.

Hire SEND & SEN Classrooms in the UK
Need send & sen classrooms for a fixed period? Hire it instead of buying. Adacon manufactures the building to your layout and hands it over on hire terms, then collects it when you no longer need it — with the same quality, fit-out and design freedom as a purchase.
Hire terms are flexible — tell us how long you need the unit and we will confirm the rate for that period.

Built around the pupils who will use it
SEND, SEN and SEMH provision works differently to a mainstream classroom. Sightlines, acoustics, lighting, exits and the distance between a teaching room and a calming space all matter more than raw floor area, so we plan the layout around the group first and the module count second.
- Main teaching room sized for the group rather than a full class
- Smaller intervention or one-to-one rooms off the main space
- Breakout or calming space reachable without crossing the teaching room
- Sensory room provision, with lighting and power planned for it
- Accessible WC and washroom provision, with changing space where needed
- Staff base or office with clear sightlines into the teaching area
- Controlled single entrance, with a second means of escape
- Storage for equipment and resources, and a kitchenette where required
- Level or ramped access and a direct route out to an outdoor area
Example configurations
Buildings combine P300, P400, P500, P600 and P700 units, with bespoke options. A separate P600 provides approximately 11.4 m² usable internally. Example areas use a conservative per-module allowance before partitions; open joins can provide more space. Units can be combined or stacked over two storeys.

- Bespoke
- Bespoke sizes considered to suit your brief — contact us
- Joined internal space
- Open joins remove the adjoining shell walls and can increase usable space. Final clear area depends on layout and partitions.
- Unit height
- 2.40m external / 2.16m internal
- Storeys
- Up to two storeys, subject to final project design
- Delivery
- UK mainland and Northern Ireland — transport quoted separately
Adacon modular buildings use P300, P400, P500, P600 and P700 units with external lengths of 2.9m, 3.9m, 4.9m, 5.9m and 6.9m, a common 2.2m width and 2.40m external / 2.16m internal height. The sizes can be combined to create more tailored floor areas and building shapes, joined side by side or stacked to two storeys subject to the final project design.
What's available for a send & sen classroom
Buildings can be configured for SEND, SEN and SEMH use, subject to project-specific requirements. We do not make blanket claims about EHCP, DfE, safeguarding, accessibility or building-regulation compliance — the specification is agreed per project against your own requirements and advisers.

Built from five unit sizes, or bespoke
Every Adacon building is made from these units, or built to a bespoke size. Units can be combined — joined end to end, side by side, or stacked to two storeys — to create larger buildings.
