Roof terraces, roof gardens and podium planting require considerable research and planning. One of the first constraints to consider is the available load as this determines the elements that can be included in the final design. You may need to hire the services of a structural engineer to avoid costly mistakes further down the line.
Roof gardens provide valuable outside space for offices, flats and apartments. Additionally, planting and structures help to provide screening from unsightly views or conversely, to maximise a view. Gardening up high presents unique challenges, being exposed to the elements. Plants can act as windbreaks but they will need plenty of irrigation and drainage to survive.
Roof gardens and terraces are a great way to extend the inside, outside. Planters, raised beds, seating and lighting can all work together to create a garden in the smallest space.
Green roofs are another way to green our cities and encourage wildlife into our gardens. A garden at roof level is described as an intensive system whereas a green roof is an extensive growing system. These are predominantly designed to catch rainwater and can be used on sheds, outbuildings and new extensions. Typically a green roof is planted with sedum matting or wildflower turf on a special layered matting or in pre-grown trays or tiles.
There are still loading implications to consider with a green roof, and it is worth consulting an expert for guidance on installation.
