New flats

Today I was offered a secure tenacy with a housing association, in one of these new blocks of flats, but I don't know which one. (When I first saw them I thought they were portacabins!) But I'm in a privately rented flat, and lovely as it is, it's always taken big chunk of my income to stay here. Do I want to live in a box? Don't know. If it's a nice box, yes. This is going to be a big decision.
