Olga Steb
This is the largest performing arts center in Europe and one-of-a-kind in London. The brutalist-style building was taken by the center's halls and facilities in 1985. The center managed by Kate Bush offers concerts (both classical and contemporary), theater shows and has a library, three restaurants and an observatory. Get inside to see their shows (they have a free gallery for experimental stuff downstairs), take a walk around (don't forget about the patio overlooking a pond and a small chapel) and head to Lounge veranda.
