The Roundhouse was built as a steam-engine repair shed in 1846, and then became a warehouse before falling into disuse for 25 years and reopening as a performing arts venue in 1964 hosting acts like Jimi Hendrix, The Doors and Pink Floyd. It was redeveloped between 2004-2006 and is one of my favourite music venues in London; it’s a beautiful building, has a great sound and isn’t too huge so feels fairly intimate. Some highlights for me this year were The Flaming Lips, David Byrne & St.Vincent and the Timepiece installation by Conrad Shawcross.

Outside of the major players (Tate, V&A, RA) this is probably the best programmed gallery in London

The Barbican has so much to offer! From beautiful architecture, to a conservatory, amazing art, films, music and performances. It is such an exciting and relaxing place to hang out. Even if you don't have a purpose for visiting the Barbican, it's good for just having a tea with a friend. 

Excellent gallery. It has big rooms which often feature large pieces and admission is free.

Just down the road from where I live is this Art Deco cinema where mainly locals go. Watching films and sitting in this old theatre really adds another level to the experience.
