Hi, I'm new too, very addictive. The Tradesmans Homes are still there, they're also called Lily Croft, they are run by a charity. I've been in some of them over the years, was fascinated by their architecture from the first time I saw them and as Stranda said, they are a wonderful oasis in the area, they are hidden away behind the police station in what has become a very built up area of Bradford. There's a lovely description on the charities commission website,
http://www.charity-commission.gov.uk/registeredcharities/showcharity.asp?regno=224389"FOUNDED 1867 SCHEME OF 30 MAY 1972 RULES AS AMENDED 6 MARCH 1974 AND 12 JUNE 1978
Objects TO ERECT AND MAINTAIN AT LEAST THIRTY DWELLING HOUSES FOR DECAYED TRADESMEN AND OTHERS, BOTH MALE AND FEMALE, WHO HAVE AT ONE TIME OCCUPIED A GOOD POSITION IN SOCIETY, BUT THROUGH ADVERSE CIRCUMSTANCES HAVE BEEN REDUCED TO COMPARATIVE POVERTY AND NEED BENEVOLENT AID TO ENABLE THEM TO KEEP CLEAR OF PUBLIC CHARITY."
I think a resident told me a few years ago that you still have to meet conditions to apply for one, though hopefully you don't need to be decayed any more....
PS just been browsing around (I need to get out more!) and if you click on "account documents" from the link above, then on 2007, there are some fantastic photos of the homes as they are now and a detailed history.
