How much value does a basement add in NW London?
The effect of an improvement depends on the starting condition, layout, specification, buyer or tenant context and market at the time of assessment. Separate functional or repair benefits from any unverified financial uplift.
Where a commercial outcome matters, obtain an independent property-specific opinion before work and revisit it when the design or budget changes. Keep that assessment separate from a contractor's construction quote.
