John Perryn School, Acton
Two-storey precast concrete frame
The project incorporated a primary school and
a Sure Start children’s centre, creating a welcoming site with a
strong civic presence. It is designed to allow access by a
variety of users without compromising pupil or staff
security. The school is arranged over two floors to create a
compact, light-filled building that frees up much-needed site
The project was a Pathfinder scheme for the
DfES Primary Capital Programme and thus was required to meet high
educational, environmental and design targets.
A precast concrete panel wall and slab system
allowed for rapid construction and a high quality, durable exposed
internal finish. Phased construction ensured that the school
remained fully functional throughout the site-works. The
prefabricated concrete panel system was fast and economical, and
reduced programme time and waste without jeopardising future
internal flexibility. The precast frame was constructed by
Buchan in just 35 working days on-site.
The existing school building on the site was
demolished after the new school was completed.
The concrete benefits
Solid concrete walls and exposed ceiling
soffits provide thermal mass for the building which is enhanced by
the use of night-time cooling, cross ventilation and high levels of
daylighting. The building design achieves a 33 per
cent reduction in CO2 over the current building regulations
requirements. Ninety per cent of the demolished school
building was recycled or reused on site.
