The GF Victoria luxury hotel which opened its doors in 2018 in Costa Adeje / Tenerife, not only impresses with its sustainability concept, but has also become a visual attraction in this popular tourist destination thanks to its three steep pitched green roofs. With slopes of up to 45° and a verge length of up to 33 m, these green roofs are among the steepest of their kind in Europe and could only be realized under very specific conditions. Steep pitched roofs usually reach their natural limit at a pitch of approx. 35°. So a variety of conditions had to be fulfilled that a roof with slopes going beyond could be greened.
Apart from the functional reliability of the material installed, other aspects played an important role during installation. First and foremost was the enthusiasm and commitment of all those involved, who never questioned the success of the project. In addition, stable weather conditions during installation were important in order to be able to go without the usual pre-cultivated sedum mats which are normally used on steep pitched roofs. Instead a selection of drought-resistent shrubs and perennials adapted to the Tenerife climate and well coordinated in colours was planted giving the roof its unique and extraordinary design.
