G2A Architecture Ltd
Guernsey-registered company (Registry no. 1-57268); Nampara, Calais Road, St Martins GY4 6AP; email hello@g2a.gg. Classified for architectural and engineering activities and related technical consultancy. Not RICS-regulated. 8 applications as agent 2022-2025.
The properties they work on
Too few of this firm's applications (1) 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 (3), Torteval (1), Vale (1). Properties currently for sale in those parishes ask around £5,651/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
£37,031–£64,844 average, estimated per application from its own description text using this site's planning cost model — a rough guide only, not a quote from G2A Architecture 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.
