Our scope of works at Caroline Sharpe House included not only a sedum green roof, but also an area of rooftop landscaping to provide a pleasant roof terrace with a view over the city.
On the podium deck, we first installed protective layers to allow expansion and contraction of the various finishes without compromising the integrity of the waterproofing membrane below. On top of these layers we install a drainage board, to retain enough water in the system to stop any plants from drying out whilst allowing any excess water to drain off the roof effectively.
Once the base layers for the system are installed we start to think about how the roof will be finished. On this project we incorporated three different types of paving; two different sizes of pre-cast concrete paving slabs and block pavers in ochre and buff to differentiate between different areas of the terrace. These were installed in a porous system with no mortar, to allow water to drain to the outlets and avoid pooling on the surface.
As well as the paving, we installed an area of artificial grass, to provide a minimal maintenance alternative to lawn turf. As well as this artificial greenery, we installed planters with a range of vegetation planted to give a range of colour throughout the year.
Finally, benches were installed to give a pleasant seating area to enjoy the new terrace from.
