Another award for rooftop greenhouse Agrotopia, this time the BTTV
Once again Agrotopia has won a prestigious award. This time the first prize of the Benelux Trophy for Hot-dip Galvanisation in the Aesthetic Galvanisation category. Since its opening, the roof greenhouse has won several design awards, such as the WAF and the Belgian Construction Award.
Renovation garden centre Dvorak
In Czechia we have started with the renovation of garden centre Dvorak. The 1,400 m2 wide span structure was built by us in 2008. The roof, screens and ventilation windows will be replaced in order to better monitor and control the indoor climate in the garden centre. This will result in further energy savings.
Completion first phase Plantorama Amager
The first phase for Plantorama Amager, building the new restaurant, has been completed. Now we have to wait before we can start with the second phase: the construction of the 5,000 m2 garden centre. The old garden centre will be demolished to make way for the new, larger and more sustainable building. The restaurant will then be connected to this new garden centre.
