Older, solid-walled homes
22% of the housing stock in these neighbourhoods dates from before 1919 and 19% from before 1900. Expect solid walls rather than cavities, so damp diagnosis needs care: cement renders, plastic paints and raised ground levels trap moisture in walls that were designed to breathe.

Listed buildings
Historic England lists 237 buildings in and around Falmouth, including 1, 2 And 3, Bank Place (Grade II*); 48, Arwenack Street (Grade II*); 51, High Street (Grade II*). On a listed home, like-for-like repairs with traditional materials are the rule; your surveyor should flag anything that looks unconsented.

Conservation area
Conservation area here: Falmouth. Permitted development rights are narrower inside a conservation area, so extensions, windows and solar panels may need planning permission.

Flood risk (rivers and sea)
1 of 100 postcodes checked are in Flood Zone 2 or 3, so most of Falmouth sits outside the river and sea flood zones. Low-lying streets and surface water can still catch people out.

Radon
The 1 km radon map square at the centre of Falmouth is class 6: an estimated 30% or more of homes are above the radon Action Level. 100% of the sold postcodes we checked fall in a radon Affected Area. Check whether the house has a radon sump or membrane, and if there's no test result, plan one in the first year.

Mining and mundic
A mining search is standard practice in Cornwall, and pre-1950 concrete construction can trigger a mundic test (RICS guidance).

Ground and building stone
Under most of Falmouth the bedrock is mudstone, siltstone and sandstone (71%) and breccia (25%). This is the 'killas' country of slate and shale; older homes are often rubble stone, sometimes slate-hung, and weathering of soft stone and mortar is common.

Coastal exposure
At roughly 0.9 km from the open sea, exposure matters: check render, chimneys, window seals and metalwork for salt and weather damage.

Leasehold flats
With 27% of sales leasehold, many Falmouth buyers face a lease: under about 80 years left, extension costs rise.
