The "brutalist edifice" that looms over Colliers Wood has won yet another unwanted title.

Satirical website S*** London - which documents "urban decay at its finest" - crowned the "grim" Brown and Root tower the ugliest building in the capital.

It picked up the honour in the website's first awards, announced on Friday.

The website describes the vacant 17-storey building as: "A grim black edifice that looms over this corner of London like a brutalist twist on Tolkien.

Rumours that this actually sucks in light and feeds off the joy and vigour of local residents are unsubstantiated."

The tower was named the ugliest building in London in a 2006 poll, and one of the 12 ugliest in Britain in a 2005 poll by Channel 4.

Community groups and Merton Council have urged owner Criterion Holdings to develop the site, which was built in the 1960s, but there are currently no firm plans to do so.

Second place went to the Great Eastern Street car park in Islingston, while the London College of Business and Computer Studies in Clapham took third.

The site has promised an award ceremony for those who submitted pictures to the competition in a "down at heel" pub next week. Other categories included best/worst shop name - won by Croydon's Abra Kebabra - and most depressing view from work.

Website creator Patrick Dalton described it as a collection of "photographs of the unintentional human comedy that surround us in the city".

It features unusual sights, graffiti and misspelled shop names and signs. A book featuring pictures from the site, called snapshots from a city on the edge, was published in July.
