Gasholder Bases

National Grid are inviting architects and designers worldwide to consider opportunities for redeveloping empty gasholder bases into valuable structures across a variety of sites in the UK. Redeveloping an empty holder base represents a potentially better environmental and cost option compared with the typical practice of backfilling them with resources that could be used elsewhere.

Description
This competition is being launched to raise the profile of the future of gasholder bases and the subsequent regeneration this will generate. It is important to note that National Grid are unlikely to be the developer for these sites, although they hope the winning designs will attract interest from potential developers and provide a guide for the future use of sites.

There are many gasholder sites where there is potential to leave the holder base empty and install a base, a simple internal structure, and a roof. This 'product' has potential to be more valuable than the land with a backfilled holder and a conventional building. The success of this approach relies on there being a viable market for such products.

National Grid Property Holdings Ltd (NGPH) has a portfolio of well over a hundred former gasholders to be dismantled within the coming years. The engineered bases of below-ground holders represent large voids in the sub-surface. The current practice is to backfill these voids however, this is both labour and resource intensive, even if the material used is from other sites where the material is surplus to requirements. There is also a high environmental cost with the transport of material and associated dis–amenity. For these reasons, there is an opportunity to investigate alternative uses of the void space.
