no highway interest in the application
fully supportive of principle to return to single dwelling; no objection to floor plan in principle; supports window proposals with specifics on repair/retention of historic fabric, sash patterns, and glazing details, subject to corrections for inconsistencies
Registered Buildings Officer requires amendments/clarifications to protect historic fabric, particularly windows, insulation, tanking, and surviving features; Highways Division has no highways interest.
Key concern: basement tanking prevents wall breathability and may impact fabric long-term
Principal Registered Buildings Officer
Conditional No ObjectionAmendments/Clarifications required.; every effort should be made for their retention and preservation; the original box sash frames should be retained with only the sashes replaced; tanking the walls will not eradicate the issue, and could impact upon the building in the longer term and I therefore do not support this element of the proposals.; Where historic joinery details survive they should be left in their original location and not removed
Conditions requested: suitable conditions subject to further details submitted by the applicant
