While parked in Hastings (at a seafront car park eating the great British favourite of Fish & Chips). I spotted this seafront building. It is called Pelham Crescent in the centre of the Crescent is a Church built in the Neo-Classical style. It was converted into an arts centre in 1998.
The Church and Cresent are above Pelham Arcade, the commercial properties go under the hill up to the church with a glass sunlight as their centrepiece. The large Georgian Houses appear to be currently split into bedsits but it looks like the whole Crescent is currently undergoing restoration work.
