The issue with Church Street is the 1970's red brick building. It has 3 ground floor units which are all empty. I don't know if the basment unit which is now occupied by a strip joint (used to be Buzz back in the day) is part of the building.
Clearly the owners of that building will have to consider what to do. Either drop rents significantly and hope for new tenants or redevelop. Church st has a fairly vibrant restaurant/bar scene now with Cafe Citta, Applejacks, 10 feet tall, Old Arcade, erm Greggs plus the Owain, Market Tavern etc just around the corner. A3 seems to me to be about the only option available. I don't think residential or office space is feasible and retail would stretch it a bit. If they redevelop they could reconfigure the ground floor to make the units more adaptable for A3 use but it would be quite an undertaking.
Here is an advert for the unit occupied by Applejacks that gives an indication of the rents that can be had in that area

How much would it cost to redevelop that building? Would it be worth it given the rental yield? I suppose thats the analysis the owner will have to undertake. I'd like to see the building knocked down and replaced with something befitting it's location but realistically I can't see that happening because the rental income wouldn't support a project that is likely to cost several million.
