Pocket Habitat resulted from the need to solve a problem with creating and installing a biodiverse green roof on a British Land estate.
The Pocket Habitat team includes:
Arup - a global engineering consultancy
Dusty Gedge - a leading green roof expert
Sky-Garden - the UK’s leading independent greenroof company
The conventional ‘roll out’ systems were inappropriate for the British Land project. Built like mattresses, they were bulky and awkward, requiring at least two people to shift them. They also required specialist teams to measure, survey and install, were difficult to retrofit and did not allow for localised biodiversity.
Building facilities managers were concerned these systems would inhibit their ability to access their roof’s waterproof layer when maintenance was required.
A modular tray system, on the other hand, meant individual, self contained, waterproof beds came complete with moisture mat and substrate, allowing fit and retro-fit in virtually any flat space, with no costly and time-consuming measuring up.
Being stand-alone meant the product was suitable for any size of commercial or private space, without the need for a qualified professional. Nor was maintenance required.
Once installed, the cost would be neutral compared to the conventional ‘roll out’ system. Weight was also neutral. It was versatile and allowed tailoring to meet specific biodiversity needs. Different substrate depths would also achieve greater biodiversity.
Furthermore, product standardisation reduced design time. Choice of forms – square or rectangle – and colour also gave freedom to create the user’s own aesthetic.
The problem was that while a number of green roof tray systems were available, none specifically promoted biodiversity and, more particularly, localised biodiversity.
Pocket Habitat was created to fill this void. It solved a problem with the British Land project and is now being made available for use more widely.
