Peacehaven is a £300m waste water treatment plant servicing the Brighton and Hove catchment area and features a 16,050 sqm curved green roof – the largest of its kind in the UK.
Lindner Prater worked closely with main contractor 4Delivery and architect Montgomery Watson Harza on the unique design of this project and supported Southern Water in securing planning permission.
The metal deck single ply structure with shear batten support overcame initial design concerns and by specifying a fully turfed landscape – rather than a standard sedum green roof – project leaders were able to convince planners of its ability to marry perfectly with the surrounding countryside.
One of the biggest challenges on site was transferring thousands of tonnes of substrate onto the roof and covering the complete area using mobile tower cranes. A series of conveyor belts were used to transport the volume of material, which was then raked to follow the curve of the building.
The seed mix was carefully chosen to react with the seasons in the same manner as the immediate landscape and the turf was grown offsite for 15 months to ensure it was established from the outset. The area is strimmed as part of on-going maintenance to keep the loading at an optimum level and maintain a healthy turf.
