Older, solid-walled homes
50% of the housing stock in these neighbourhoods dates from before 1919 and 47% 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.

Conservation area
Conservation area here: Newlyn. 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 37 postcodes checked are in Flood Zone 2 or 3, so most of Newlyn 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 Newlyn 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
Two Cornish checks to expect: a mining search from your conveyancer, and, for concrete-block houses from before about 1950, a mundic screening test.

Ground and building stone
Under most of Newlyn the bedrock is mudstone, siltstone and sandstone (78%) and granite (BGS class: felsic rock) (18%). Granite brings radon with it, and granite walls, though durable, can let wind-driven rain through open joints.

Coastal exposure
Newlyn is within about 0.7 km of the open coast. Salt air shortens the life of metal fixings, window frames and render, and wind-driven rain finds weak spots in walls.
