Project moment

The client wants a fixed fee, early budget range and spring construction start. The remaining questions are specific: fabric at the opening, detailed rear-range junctions, garden/access implications and the likely approval route.

The project needs to define what further work may be required before these assumptions become reliable.

Your task

Identify the most useful next-stage definition.

Use the Project Material on the right, then answer below. →Use the Project Material above, then answer below.

For this page

PREFERRED DIRECTION DEPENDS ON
• Targeted investigation of fabric and structure at the proposed opening.
• Detailed design of rear-range junctions, services and retained timber.
• Confirmation of garden threshold, access and landscape implications for the extension proposal.
• Verification of the relevant consent route and local requirements.
• Proportionate supporting heritage information.
• Possible heritage consultant/specialist input if evidence, complexity or local requirements indicate that it is needed.

Stage 4 · Managing client, cost and programme

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

Earlier stages

Known: The preferred direction is a compact rear extension with limited reworking of the rear range.
To establish: The specific fabric affected by each credible opening or internal alteration.
Whether further investigation is needed to compare likely effects before a preferred option is selected.
Fabric, structure and evidence of development at each potential opening location.
The effect of a new opening or window-to-door conversion on the rear elevation, internal space and surviving fabric.
Whether an existing opening can be used or adapted with less effect.
Whether adapting the existing rear window or creating a new opening is the more appropriate response once fabric, structure and elevation effects are known.
Keep under review: How Options A, B and C meet the client brief and affect the rear range, identified fabric, internal spaces, garden, threshold, access and current site relationships.
Whether proposed openings, services, threshold changes, footprint or landscape changes can be avoided, reduced or relocated.
Opening size, proportion, threshold, access, drainage, joinery and relationship to the proposed extension.
Whether opening-up or specialist structural/fabric advice is proportionate before the opening position is fixed.
Retention, repair or alteration of exposed timber, finishes, doors and evidence of earlier openings.
Opening size, proportion, threshold, access, drainage and garden landscape implications.
Decision point: Before the preferred direction is treated as settled, confirm affected fabric, opening strategy, detailed effects, proportionate evidence requirements and the relevant consent route.
Before scope, cost, programme or approval outcome is presented as fixed, confirm the opening strategy, affected fabric, relevant consent route and proportionate supporting-information requirements.
Client conversation: The extension requires planning permission; consider separately whether the extension and related works require listed building consent, and confirm that position as design and evidence develop.
Allow for proportionate supporting heritage information and, where justified by the evidence gap, complexity or local requirements, a heritage statement and/or specialist heritage advice.
Explain that preparation, determination and possible clarification or design refinement may affect timing.

Your initial view

What should be included in the next client proposal?

A defined investigation stage with an allowance for heritage information and possible specialist advice, reviewing scope, cost and programme once requirements are clearer.Nothing needs to change; heritage can be dealt with after the client approves a fixed scope, price and construction date, as it would be on any other house.Delay every client decision until all possible heritage questions about the property have been resolved.Promise a fixed price and start date to keep the client committed, then use a general “heritage” contingency if the assumptions prove wrong.
