Moreland Primary School, in the London Borough of Islington, is a new purpose-built school, nursery and children’s centre. The £12.4m development, carried out by Morgan Sindall, also included demolition of the existing school which would remain in operation throughout construction.
Phased construction was carried out over a 12 month period before the school’s opening in autumn 2016. The project maximised all usable outside space. For example, the school roofs were designed for play, education (science lessons and children’s allotments), general staff and pupil enjoyment.
The Inner London development had very limited construction space due to its location and phased construction programme. The original design included below ground attenuation tanks to provide temporary storage and controlled discharge of storm water. This presented a problem at the outset as it would significantly reduce site storage space and limit access to other sub-contract trades, subsequently delaying the programme of works. The challenge was to develop a new method of storage/discharge which would not adversely impact upon the rest of the project. Any solution would have to be sensitive to Islington’s Biodiversity Action Plan which looked to protect existing site ecology and enhance biodiversity through a range of measures including a biodiverse roof system.
Due to the technical expertise and experience of similar working conditions, ABG designed a versatile ABG blue roof system which would eliminate the need for attenuation tanks at ground level whilst still allowing for the range of roof finishes required. ABG’s knowledge and experience also meant that the work could be completed under strict and phased timeframes creating valuable storage space for other trades materials at roof level. The incorporation of ABG’s biodiverse roof system helped to maximise BREEAM credits and meet the criteria laid out in Islington’s Biodiversity Action Plan.
