John Fitzgerald Photography

Description

A well-positioned commercial unit extending to approximately 1,679 sq ft, offering excellent roadside visibility and strong passing traffic, making it ideal for a range of business uses. The property benefits from a generous on-site car park providing space for approximately 9–10 vehicles, in addition to a small courtyard area. Available from 2027, the premises provide a flexible layout which can be adapted or configured to suit an incoming tenant’s specific requirements, presenting an excellent opportunity to tailor the space to your business needs. This is a highly accessible and versatile unit in a prominent position, well suited to occupiers seeking strong visibility combined with practical parking provision.

A useful first look

Explore rooftop solar potential

Explore the official Guernsey rooftop map and our guide to the checks that matter. Find the correct building on the map; we have not matched or assessed this property’s roof.

Indicative map only—not a roof survey, energy quote or planning approval. For a flat or rented home, check who controls the roof.

Nearby

Nearest match in each category, from the island place register (OpenStreetMap plus local sources) — a broad list, not a guarantee that every business is included. Distances are straight-line ("as the crow flies"), multiplied by 1.3 to approximate real road-network distance — this is an estimate, not turn-by-turn routing, and actual walking/driving routes may differ. Times assume constant average speeds appropriate to Guernsey's roads and 25/35mph limits: walking 4.5 km/h, cycling 14 km/h, driving 30 km/h — not open-road speeds, and they don't account for traffic, parking or terrain.

Telecoms masts nearby

The nearest licensed mast site is 183 m away in a straight line — not walking distance, and not necessarily visible from the property. From the Guernsey Competition and Regulatory Authority’s mast audit register, read 2026-09-20.

What this does and does not tell you

It does not say which masts carry 5G. The regulator’s register records the operators, the height, the structure and the measured emissions — it records no radio technology, so this site cannot identify a 5G site and does not guess. 5G reached Guernsey in early 2026 and the first sites were in and around St Peter Port.

The emission figures are the regulator’s own measurements, expressed as a percentage of the ICNIRP international public exposure guideline. Across all 91 sites in the Bailiwick the median reading is 0.176% of that guideline and the highest is 11.24%. This site reports those numbers and draws no conclusion from them either way; the GCRA publishes the full audit for each site.

Getting connected

Guernsey's copper telephone network is being retired at the end of 2026, and every property on the island is expected to be connectable to the fibre network. In practice that means a purchase completing now will be a fibre connection, and a landline-only arrangement will not survive the switch-off — worth settling before moving day rather than after it.

Three providers sell residential broadband here: Sure, JT, Airtel-Vodafone. Airtel-Vodafone was acquired by Sure in November 2024, so the market is more concentrated than three names suggest.

This site has no per-address availability feed and so makes no claim about the speed or price at this property — check with a provider against the actual address before you rely on it. No provider pays this site anything, and these are ordinary links, not referrals.

What would improving it be worth?

Value added is the extra floor area priced at £6,304/m² — the midpoint asking price per m² among 10 St Martin 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.

Read this as an order of magnitude, not a promise

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.
