On the protected register
- Protected building — OAKLEY HOUSE, ROHAIS, ST. PETER PORT, GUERNSEY, GY1 1YJ (ref A207340000-PB402)
Alterations, extensions and demolition need planning permission that an unprotected building would not, and consent can be refused on grounds of the fabric itself. Repairs are expected to be in matching materials.
Matched from the States of Guernsey protected register by address, using the same matcher as this site’s sold-price and planning history — so it can match a neighbouring property with a very similar address. Treat it as a prompt to check the register itself, not as confirmation, and confirm with your advocate before relying on it. Protection is a material fact about what you can do to a building, not a comment on its condition. Register read 2026-09-27.
What would improving it be worth?
Value added is the extra floor area priced at £5,983/m² — the midpoint asking price per m² among 44 St Peter Port properties currently for sale that publish a floor area. Cost uses real Guernsey 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 Guernsey 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 |
£83,761 | £70,000 14 m² · mid spec new build range £56,000–£84,000 |
+£13,761 | 97% (1,533) |
| 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 |
£119,658 | £60,000 20 m² · mid spec refurb range £40,000–£80,000 |
+£59,658 | 97% (153) |
| Two-storey extension Roughly 14 m² on each of two floors. ~28 m² |
£167,521 | £140,000 28 m² · mid spec new build range £112,000–£168,000 |
+£27,521 | 93% (87) |
| Garage, annexe or outbuilding Detached space is worth less per m² than main-house floor area. ~18 m² |
£64,615 | £90,000 18 m² · mid spec new build range £72,000–£108,000 |
−£25,385 | 90% (761) |
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 Guernsey'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 — who is actually filing applications shows which firms are active and how often their applications succeed.

Matched by house name/street and parish against the States of Guernsey property 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.
