I used to live in Camberwell on the 6th floor about 10 minutes’ walk from this building, it always scared me that we were on the highest floor in the furthest flat from the single stairwell, and I was never that happy about it.

When I look at the cost of flats in London, I wondered why the 15th and 16th floor flats near me are cheaper than the lower ones, despite the view they must have, and now I know!
