Condition Report

  • Chimneys – Rendered chimney stacks to ridge stump remains only; that to gable at right lost due to partial collapse of gable wall. Chimney stump only remains to left gable and separating wall at carriage-arch. Chimney stumps appear to have been recently re-rendered. Corbelled rough-cast rendered chimney with clay pots to rear return.
  • Roof – Extensive slipped and broken slates. Patch repairs in fibre cement. Rooflight to rear slope heavily corroded with broken glass. Extensive vegetation growth to return. Partial loss of roof structure and cover.
  • Dormer – Timber dormers to front roofslope appear in poor condition. Evidence of damp causing distortion of timber cheeks. Poor decorative order. Extensive paint peeling.
  • Rainwater goods – Qualitative cast-iron gutters retained with single round cast-iron downpipe. All heavily corroded and in poor condition. Half-round uPVC gutters and round downpipes to rear return.
  • External walls – Painted block marked lime rendered walling. Extensive cracking and peeling of paint suggests damp penetration. Render appears to have been renewed at first floor level. Evidence of extensive vegetation growth to gable wall now removed. Extensive vegetation growth to rear return. Return wall forms boundary to site. Partially re-rendered and partially exposed brickwork.
  • Surround in poor condition.
  • Windows – All windows boarded up.  Wrought-iron guard remains to ground floor window.
  • Miscellaneous – Surface-fixed cabling to first floor string course. Billboard effects to gable wall. Gap site adjacent to site extensive overgrown.
  • Structure – Significant crack to centre of gable wall at rear of chimney appears to have displaced capping to verge. Structural cracking above openings. Street facade appears to bow slightly at first floor.
