What the analysis was worth.

Victorian terrace requiring a rear extension and loft conversion.

An early build expectation of approximately £150,000 had been established before any detailed cost analysis. The property was approaching purchase, and key financial decisions needed to be made before exchange.

• Historic structural movement requiring additional works.
• Party wall repairs and missing loft fire separation.
• Floor structure requiring reinforcement for the proposed layout.
• Existing drainage conflicting with the extension footprint.

Rather than proceeding on the original assumptions, the purchase price was renegotiated, additional finance was arranged before work commenced, and the loft conversion was phased into a later stage of the project.

One-bedroom flat marketed as recently refurbished with a private garden.

The buyers had an accepted offer and only days before exchange. Condition concerns had been raised, but with no figures attached — nothing to turn the risk into a number, or into a negotiating position.

The report combined listing photography, property data, comparable sales and completed residential project data to identify likely hidden costs and establish an evidence-based negotiating position.

• Signs of historic water ingress.
• Evidence of previous damp treatment.
• Garden wall movement.
• Asking price inconsistent with the property's true condition.

The buyers renegotiated successfully before exchange, using the report as supporting evidence.

Three-bedroom semi-detached property.

The property had remained unsold for several months, and a significant price reduction had been recommended.

The report concluded the asking price was broadly supported by comparable evidence. The issue was presentation rather than pricing.

Instead of reducing the asking price, targeted improvements were completed before relisting. The property subsequently sold close to the original asking price.

The objective was to establish a realistic budget before appointing a design team or obtaining contractor quotations.

The report produced evidence-based cost ranges using outline proposals and property information, identifying no significant structural risk factors.

The report became the benchmark for contractor negotiations. The selected contractor's pricing aligned closely with the analysis, and the project completed within budget.
