What would improving it be worth?
Value added is the extra floor area priced at £2,513/m² — the midpoint asking price per m² among 5 Ramsey properties currently for sale that publish a floor area. Cost uses real Isle of Man build rates: £4,000–£6,000/m² new build and £2,000–£4,000/m² refurbishment, depending on quality. Net is against the mid rate. The last column is how often Isle of Man actually grants that kind of application.
| Improvement | Value it might add | Likely cost | Net | Granted |
|---|---|---|---|---|
| Add a bedroom (single-storey extension) A modest double plus circulation, built new. ~14 m² |
£35,182 | £52,500 14 m² · mid spec new build range £42,000–£63,000 |
−£17,318 | 0% (314) |
| Loft conversion with a bedroom Works inside an existing roof, so it prices as refurbishment rather than new build — which is why it usually wins. ~20 m² |
£50,260 | £41,000 20 m² · mid spec refurb range £33,000–£50,000 |
+£9,260 | 0% (46) |
| Two-storey extension Roughly 14 m² on each of two floors. ~28 m² |
£70,364 | £105,000 28 m² · mid spec new build range £84,000–£126,000 |
−£34,636 | 0% (66) |
| Garage, annexe or outbuilding Detached space is worth less per m² than main-house floor area. ~18 m² |
£27,140 | £67,500 18 m² · mid spec new build range £54,000–£81,000 |
−£40,360 | 0% (199) |
Two things it cannot see. First, it prices floor area at the local average rate — it doesn't know your plot, your roof, your outlook, or whether an extension is physically possible; nor whether your street has a ceiling price that no amount of extending beats. Second, the rate comes from asking prices of other properties currently for sale, because the Isle of Man's sold register records no floor areas at all — so it reflects what sellers ask, not what buyers paid.
The obvious alternative method is worse, which is why it isn't used here: comparing a typical 3-bed with a typical 4-bed suggests a bedroom is worth around £430,000 island-wide. It isn't — a 4-bed is generally a bigger house on a bigger plot, so that figure measures the mix of what's for sale, not the value of adding a room.
Before spending anything, get a builder's quote and talk to an architect — what work of this kind actually gets approved here shows how often applications like yours succeed, and on what grounds the refusals go.

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.
