MARELD has a solid experience of green systems and converting roofs to green gardens. For amongst others Riksbyggen we have designed a number of roof gardens in connection with renovation and waterproofing of roofs. Existing constructions are an additional challenge as the design is not always intended to accommodate structures with vegetation. In these projects, all roof areas have been transformed from worn asphalt-dominated roofs with scattered planting boxes into green and living residential gardens. The pictures show Uddevallahus brf 14 (2O13).
