Stackhouse Design Ltd
LOW CONFIDENCE / unverified as a distinct Guernsey practice: the only "Stackhouse Design" found online (stackhousedesign.co.uk, principal Peter Stackhouse) is based in south-west England with no stated Guernsey presence. Could be the same UK firm taking on remote Channel Islands commissions, a different/unrelated local practice with no web footprint, or a data-entry variant. Included on the strength of 4 genuine Guernsey planning applications under this exact agent name 2022-2025 (incl. Martello House, Fort George and White Lodge, Les Vardes, both St Peter Port) — flagged for manual verification.
The properties they work on
Too few of this firm's applications (2) tie to a later sale with a real price to give a reliable average, so this is the area picture instead. Most of their filed work is in St Peter Port (4). Properties currently for sale in those parishes ask around £6,093/m².
Stated as the parishes they file in rather than an average value, because inventing a figure from one or two matched sales would be worse than saying we don't have it.
Work-type mix
Classified from each application's own description text, most common first — the same keyword model this site's planning cost estimates use. Select a type to filter the applications below.
Typical cost of work
£8,125–£18,750 average, estimated per application from its own description text using this site's planning cost model — a rough guide only, not a quote from Stackhouse Design Ltd or a reflection of what any specific job actually cost, and it does not include design fees. Each row below also carries an estimate at the prices of the year it was filed, deflated with the island house-price index — a proxy, since that index tracks house prices rather than construction costs and the two genuinely diverge (materials spiked in 2021–22 well beyond house-price growth). No Guernsey construction-cost index is published, so this is the best basis available, and it is an estimate on top of an estimate. 2 demolish-and-rebuild applications excluded from the average — that category prices per m² of the rebuild, which isn't recorded per application here.
