Warm summer nights should be spent in the high grass in Hampstead Heath above the ponds. For midsummer bring herring, snaps and songs and stay until sunrise!
It's such an iconic building and it's always a joy to be anywhere near it. It just dominates the landscape around it. Ever since I first saw the cover of Pink Floyd's Animals I've loved it and I still do. There are always reports in the news for plans for developers to spend billions on refurbishing it. I'd genuinely prefer it to remain as it is rather than see it being turned it into a massive shopping centre full of chain stores. The thought of it being turned into some kind of Westfield full of people on Facebook on their laptops in a Starbucks fills me with rage.
Donlon Books is an atmospheric little bookstore on Broadway Market (in East London.) They sell rare art books, style publications, and homemade photography zines.
A small place to eat with great vegetarian/vegan food just off Camden High Street. This place does an amazing buffet at a great price, as well as serving reasonably priced tea and juices.
The AA is Britain's oldest school of architecture, but anyone can take advangte of the great work going on there. You can catch really interesting public lectures and free exhibitions throughout the year. There are also occasional installations and event launches, a bijoux cafe and brilliant bookshop. A great place to hang out with the builders of the future.
