If you want a peaceful day out of the busy city, Highgate doesn't really feel like London. The cemetery is interesting and peaceful, there's a tour of the old half which is definitely worth the money. Karl Marx, among others are buried there.

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

Great selection of books and magazine with a big focus on rare. out-of-print books Japanese photography. Can sends hours in this little shop. I'd try to avoid on Market day (Saturday) if you want to have a good look as it can get a bit busy for such a small space.

Designed by Wells Coates, the Isokon Building opened in 1934 and was the first apartment block to be built using reinforced concrete. The Isokon Gallery is open at weekends telling the story of the Isokon building, the pioneering modern apartment block as an experiment in new ways of urban living.

Barbican, a residential estate in central London, is known for its brutalist architecture, almost a social experiment on how to live in an estate. I love walking around this area looking at the geometric shapes, the contrasting public spaces and the use of materials. The term brutalist originates from the fresh word for ‘raw’, and concrete is typically used as one of the main materials.The Barbican centre located in the centre is an arts centre and the largest of its kind in Europe, and was opened in 1982. The centre is used for classic and contemporary concerts, teatre, film screenings and art exhibitions, and houses a library, restaurants, cafes and bars. The areas’ architecture really invites you to go on a photo safari as there are great angles and light everywhere.
