Project moment

During detailed design and opening-up, damaged plaster is identified around an altered opening in the rear range. The contractor proposes removing the damaged material and replastering with gypsum because it is familiar, quick and readily available.

The project needs to decide whether that is an appropriate repair assumption before the specification is issued.

REPAIR ISSUE
• Patchy historic plaster and later repairs are present around the altered opening.
• The plaster type, condition and cause of deterioration are not yet confirmed.
• The rear range has exposed timber and evidence of earlier alteration.
• The contractor proposes full removal and gypsum replastering.

This stage’s entries appear here as you save each page. The record so far is below.

Earlier stages

Known: The proposal has been refined to retain identified timber and early doors, limit rear-range intervention and reduce effects on garden/access relationships.
To establish: The scope of development requiring planning permission.
Whether the proposed extension, opening strategy, internal alterations, services, threshold or related works require listed building consent.
Current local validation requirements and any other relevant local control affecting the proposal.
The proportionate information needed to explain significance, effects and design response.
Current local validation requirements and any other relevant local control.
The proportionate drawings, evidence and supporting information needed for the proposal.
Whether a heritage statement and/or specialist heritage input is proportionate.
Detailed materials, junctions, service routes, protection measures and any information required by conditions or further approvals.
Keep under review: Detailed materials, junctions, service routes and conditions requiring further approval or confirmation before work starts.
Whether technical development or site constraints alter the approved heritage response and require a further decision.
Decision point: Before submission, confirm that the planning application, listed building consent position and supporting information are proportionate to the works and current local requirements.
Before submission, confirm that the application material explains the relevant significance, effects and design response proportionately.
Submission narrative: Significance: relevant form, fabric, spaces, site relationships and setting.
Effects: extension, opening, internal alterations, services and threshold work.
Response: compact footprint, retained fabric, investigated opening strategy and design development to reduce effects on rear range and garden relationships.
Justification: the proposal meets the client brief while limiting and explaining the remaining change.

Your initial view

What should the project do before specifying the repair?

Identify the material, its condition and the cause of decay; establish whether repair is possible; use compatible methods; and get advice where uncertainty remains.Use gypsum plaster because it is readily available, will produce a neat finish quickly and is what the contractor is most familiar with.Replace all visible old plaster because any historic finish is likely to fail again.Leave the issue entirely to the contractor’s preferred method, because repair decisions are construction details and the contractor carries the risk.
