An example undertaken by the authors’ practice was in the restricted cellars of a series of large Victorian properties being redeveloped as ofﬁce accommodation. The load-bearing walls sat on stepped brick footings, just beneath a cellar ﬂoor of compacted earth. In this case it was possible to cut pockets out of these footings, run reinforcement through the holes, and cast the whole of the cellar ﬂoor area as a reinforced concrete raft slab. This proved a very cost-effective and practical way of enhancing the load-bearing
capacity of the premises and providing a basement slab at the same time.
