It was up to the leaseholder to fit out the entire unit: partitions, pipes, wires, etc. Although it was up to the leaseholder to design his or her own unit, building regulations required each unit to include a fire lobby. The building has become extremely desirable for media-based artists, curators, graphic/web/product/fashion designers, animators, illustrators, architects and other creatives. At the top of Limehouse Cut building, there is a large communal roof garden with views over Canary Wharf. It is private and maintained by volunteering residents. On 8 October 2008, the Langdon Park conservation area was extended to include the Spratt's Complex.
