Not the most exciting place inside, but a lovely rooftop area which not all that many people seem to know about, 2 mins walk from Old St station. If it’s packed then The Red Lion is just up the road.
This beautiful 19thC industrial building is situated in Markfield Park just around the corner from my studio. Once a sewage treatment works serving the whole of Tottenham and now a museum. The fully restored Victorian pump engine is only open to the public on the second Sunday of every month but the outside of the building and surrounding park is a worth a visit regardless.
