Architecture collective Assemble has transformed a former public swimming pool to create a new art centre for Goldsmiths college. The baths were closed to public in 1999. The space now accommodated seven new gallery spaces, a cafe and event space. 

I rediscovered this place recently having not been for years and now I keep returning. The geological galleries are my favourites.

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.

This is one of the only platforms on the London Underground that is not bombarded with billboard advertising. It's a reminder to myself of how an uncluttered environment can give you so much more room to think.

The Greenwich Observatory with its green laser beam can transfigure any night sky. If you decide to cross the Thames via the foot tunnel, make sure you look out for the green ray. You can be on one side of the meridian in a minute, and cross to the other side on the next, without even realising it.
