Hartfield Road SW19

The Client here was the leaseholder of a first floor, 1 bedroom flat in Wimbledon who proposed to convert the loft space with an L-Shaped extension into a further 2 bedrooms and bathroom. She also owned a share of freehold and with the other share of freeholder on good terms, Peter Barry were instructed to undertake a single joint expert report.

Architectural plans and a quote from a local contractor had already been obtained and an inspection of the property was undertaken. Analysis of similar 1 bedroom flats concluded that the existing value of the property was £500,000 and £650,000 once work was complete:

Subject as Existing:
62 m² / 667 ft²
Ground Floor Flat, 115 Russell Road SW19:
£525,000: 56m² / 603 ft²
First Floor Flat, 192 Hartfield Road SW19:
£498,000: 61m2 / 657 ft²
Subject as Proposed:
98 m²/ 1,059 ft²
Ground Floor Flat, 127a Graham Road SW19:
£613,000: 89 m²/ 958 ft²
First & Second Floor Flat, 75a Gladstone Road SW19:
£635,000: 79m²/ 850 ft²

The uplift in value as a result of the works was concluded to be £150,000. From this was deducted, build costs and professional fees to give a profit of £75,550. It would be typical to make deductions for risk with higher amounts for more risky projects.

This was ultimately a typical and straight forward scheme, so 10% was deemed appropriate. With the Client owning a share of freehold, the final compensation figure was £17,000.

Our surveyor, James, arrived at the house at the appointed time and was most helpful in explaining the details of the party wall agreement. He later sent the completed document as promised. Most efficient and friendly service throughout.

I was a neighbour of someone who wanted to do some changes to their dormer into a full loft conversion. The surveyor sent to review our shared walls was very young professional and helped answer all my questions and concerns. The emails from the firm were very formal, else and they were very reachable by telephone. I didn’t pay as my neighbour was carrying out the works so I can’t comment there. I would consider using this firm for further works personally

Response from the owner:Thank you for sharing your experience. We’re really pleased to hear how well the surveyor supported you throughout your neighbour’s loft‑conversion process.
