A flat owner owns the inside of the flat — not the roof above it, the ground beside it, or the right to build on either. Adding a bedroom, converting the loft or putting up an outbuilding are not options here whatever they might be worth, so they are not costed. Internal work — reconfiguring, refitting a kitchen or bathroom, replacing windows where the lease and the building allow — is a different question, and one this site has no data to price.

Same estimate model this site uses on its planning pages (UK cost ranges with the Isle of Man's 18% uplift) — a rough starting point, not a quote. Always get quotes from an Isle of Man builder before budgeting.

Matched by house name/street and parish against the Isle of Man Land Registry's transaction register — not a unique-ID lookup, so a shared house name could span more than one property. The "2026 prices" column carries each price forward at the island-wide repeat-sales index — it is what that sum of money would be at today's market level, not a valuation of this property, and it takes no account of the condition it was in then or any work done since.

Matched by house name/street and parish against Isle of Man planning applications decided between 4 Jan 2011 and 29 Dec 2023 (the government published no 2017 files, so that year is absent) — coverage is partial and not a unique-ID lookup. No bare decision date is available in this data, so the application number (which embeds its year) is shown instead. Where a "Worked on by" name appears, it's a known architect or surveyor cross-referenced by the same application number — worth a call before commissioning a fresh survey.

Estimated cost of live planning permissions
Isle of Man planning permissions lapse 3 years after grant if unbuilt; these applications fall inside that window and were not refused, so they are presumptively still capable of being implemented.

The work type shown is inferred automatically from the wording of the planning application's own description — it isn't stated by the applicant. The base cost range comes from published UK national renovation/build-cost guides for that type of project, with an 18% uplift for the Isle of Man. That uplift is not a guess: AtkinsRealis's July 2026 interim report for the Isle of Man Treasury puts Manx construction costs 18% above the UK average — joint 16th most expensive place to build on the BCIS rankings, comparable with Outer London — driven by imported materials with no local competition and a shortage of skilled trades. Figures exclude VAT at 20% and professional fees, typically 12–18%. These figures are indicative only, not a quote: actual cost depends on specification, finish, ground conditions and the contractor. For anything serious, get a quote from a local quantity surveyor or builder.
