Bents Green is a 拢9m school in Sheffield that, partly because of its pupils鈥� special educational needs (SEN) and partly because of the historic nature of the existing site, threw up a number of design challenges for architect BDP.

Completed as part of the 好色先生TV Schools for the Future (BSF) programme, the school addresses the needs of children with complex communication and interaction difficulties, including autism spectrum disorders.

The school comprises three inter-connected parts: a new-build main block with classrooms, reception and administration areas; a refurbished sixties block with specialist and general teaching rooms; and a Georgian coach house dating from 1740, which has been restored and converted into permanent residential accommodation for the children, as well as respite care. Beyond the standard highly prescriptive design requirements for SEN schools, the insertion of specialised educational, residential and pastoral environments into the historic building in particular presented key design and technical challenges.

As BDP project architect Matthew Bradshaw points out, one of the most onerous of these was accessibility. 鈥淢aximising circulation was a critical part of the project,鈥� says Bradshaw. 鈥淲e wanted to retain the historic character of the exterior but we had to ensure that the new areas satisfied accessibility requirements.鈥�

As is often the case with historic restoration, achieving this required a degree of compromise. So while the new lift does not serve the top of the former coach house鈥檚 three storeys, a modern external staircase replaces one added in the thirties. Random, uneven floor levels also meant that the new timber flooring applied throughout could not be used in some areas and was replaced with tiled flooring.

Creating legibility also emerged as a key requirement. The pupils catered for in the school respond to a tranquil, ordered and calm environment and colour emerged as an effective tool to deliver this and to subtly identify different areas, including the 鈥渉ome spaces鈥� designed to encourage a sense of safety and reassurance. Generally, circulation space was also made more legible and accessible, with existing and often circuitous routes rationalised throughout.

There was also a requirement for many of the areas to be robust and hard-wearing. Children displaying autistic traits often become particularly anxious or agitated, and each floor of the historic block has been fitted with a secure 鈥渞obust鈥� room where pupils can be comforted and reassured. In order to prevent children unwittingly harming themselves here, wall corners are rounded, carpet floors are replaced with vinyl to prevent them being uprooted, doors can open in both directions to stop children barricading themselves inside and windows are fitted with fixed catchments.

In the same manner, en-suite bathrooms to the residential bedrooms on the upper two floors are fitted with control valves that are accessible from the communal corridor to prevent baths from being over-filled. And classrooms are often not rigidly rectangular spaces but feature a dog-leg recess where children can be taken for one-on-one sessions without feeling entirely separated from the remainder of the class.

Noise was another important design issue. Many autistic children become agitated when exposed to low-level, intrusive, man-made background noise such as traffic. This meant that fans could not be used in the mechanical ventilation system, so extensive use has been made of natural methods.

Conversely, some autistic children find repetitive, rhythmic sounds, such as drumming, therapeutic but potentially almost hypnotically distracting. Therefore, a music room has been fitted with acoustic soundproofing to ensure that the noise does not interfere with teaching elsewhere.
Bradshaw summarises the design approach to Bents Green school as a 鈥渂alancing act鈥� where the challenge was to deliver a school that not only restored the character of its historic block but also created 鈥渁n intimate, safe and supportive environment for its pupils and not an institutional one鈥�.
