text: should this institional building really be in a residential landuse area?
  Some of the other building in the area could be suspect as they are business comercial educational and medical.  The buildings are reuse and have restrictions on changes to there external apperance on conservation grounds also the depth of back gardens need checking as the quaker meeting hall was in the zone but the actual house part wasn't!  It was I think originaly developed in the garden of a private home for the congregation they belonged to and I think there are private rooms in the site still of the house part. going to fix some of this today but the rest may need a review from doorbell level.
