Wasn't that called 'borrowed light'?
Ian48-- yes I agree, Plas y Dre was a mess and this smart new building looks far better.
Hugo-- Yes I would hardly call it 'affordable housing'. It isn't just the purchase price, it is the idea of all the overheads.
Parking-- the area is bad enough with people who work in town avoiding the parking fees on the prom, the area empties after 5pm, but I imagine as Dave says alot of prospective residents will chose not to have a car.
