Griffin House sits on Lever Street in Manchester's Northern Quarter, between Houldsworth Street and Faraday Street.  Judging by its architecture, this office block appears to date from the 1960s or 1970s.  When I took these images in February of 2015, it was home to, among others, N Brown, a British home shopping business.

In the mid 1800s the site was occupied by two blocks of various buildings separated by Warwick Street.  Each block contained a mixture of dwellings, industrial premises and religious institutions.  The building marked "A" below was the Lever Street Chapel belonging to the Wesleyan Methodists.  The building marked "B" was the Oldham Street Chapel School (Sunday School), also belonging to the Wesleyans.

Little seems to have changed from the time the map above was drawn and the aerial photograph below was taken circa 1940. 

If you click on the link below, you can see an image taken on the 31st of July 1960 showing the Sunday School building.
