Most impressed with the idea of your using the real brick. Also impressed with your idea to open up the attractive, but little known, Ebury Square, by creating a passage through what is at present the Police Station. Do not know all your ideas for transforming this attractive police station
Must mention that I am sad to see a relatively new attractive police station disappear. BUT appreciate your intentions to present something attractive in its place. – Yes, I do feel supportive of what I have seen so far
This is a tricky one, as London offers so many of everything already. You mentioned a coffee shop, a restaurant. These are among the only reliables, one does not need a butcher, or clothes, or bookshop (as so near the library). What about a souvenir shop as adjacent to Victoria train and bus stations? A garden centre may be welcome
Just hope the new building will not be too tall. Good luck with your plans!
