I used to own a Type 20 in the Barbican (it cost me £120,000 in 1997...). It is, or at least was, a fabulous place to live. Even then the service charges were £2,500 per annum and I was hit with a £10,000 bill after a couple of years to fix the lift as there's no sinking fund. The first thing I did, though, was to replace the kitchen. The Garchey (waste disposal unit) in particular was disgusting. The Bathroom was white tiled all over, and the flats all have underfloor heating so it was lovely to walk in there in the morning. For those who don't know the Barbican, yes the brutalist architecture can take a bit of getting used to, but the flats inside are superb - you never hear noise from other flats and they are light and airy. The landlord is the Corporation of London, i.e. the City of London, who maintain the grounds well and you also have the Barbican Centre on site with Cinema / Theatre / Concert Hall / library etc. It's within walking distance (well it was for me 30 years ago) of Soho / Mayfair / South Bank etc.
