Hopefully to answer your query:
We did have people calling into the office who expressed interest in the unit - or similar locally. (we did not advertise in any media for an occupant)
They were updated as to the unit being owned by us and the process that we were pursing in gaining a change of use.
We were more than happy to have a 'pop up unit' as long as it satistfied the current usage set out by Lewisham Planning Authorities. None of the people who came into our office had ventures of that type.

We therefore allowed a local foodbank to use it as a food delivery location to help them increase the amount of charitable donations that they receive for what is an increased number of applications for food parcels
