Biodiverse green roofs in BUDAPEST

The biodiverse green roof constructions are on the rampage in Germany, England and Switzerland, while the domestic experts have started to get acquainted with this type of green roof in the last few years.
The first hungarian biodiverse green roof was built in 2012 , on the top of an office building (Alkotás Point) in Budapest. One could say that this is an experimental roof, because we can’t use the swiss and german standards due the hungarian extreme environmental conditions, so we need to create our special technologies . The aim of our project is to change the typical extensive monoculture Sedum green roofs for a diverse perennial plantation. In terms of plant use the basic idea is: using domestic and rock steppes species.

The initial enthusiasm and a successful experiment give the result. Totally 7,000 m2 biodiverse green roof was built in Budapest over the past three years.

The next project was also on the top of an office building (Green House). 1200 m2 biodiverse green roof has been implemented. There is a major challenge by the preparation and planning of these types of roofs, because in the summer time Hungary has very long hot dry periods, which must the vegetation survive. Therefore, the basic conditions of biodiverse roofs are the heterogeneous plant application (create variety of living spaces).

Recent project is on the top of the IKEA store near Örs vezér square. We are working on a large-scale research work on 5000 m2 surface. Our aim is to create a specified plant selection for the hungarian climate.
