Valuation
The most recent sale price indexed forward to today's value is £3,728,168. This is one data point to inform the valuation. Another method is the valuation implied by what comparable homes are selling for. Homes in South Kensington are now selling for between £13,760 and £20,510 per square metre (£1,278 and £1,905 per square foot). Based on an internal area of 170 m², this implies a valuation between £2,339,000 and £3,487,000. Treat this as context only. For a valuation using hand-picked comparable sales, use the Advanced search tool — create a shortlist of similar condition homes, then export a valuation report.
