Composite Doors in Charlestown's Grade II* Harbour Conservation Area
By Cornwall Composite Doors · 7 October 1969 · 4 min read
Charlestown's Georgian harbourfront is one of Cornwall's most protected settings — here's how a composite door respects it while upgrading security.
One of Cornwall's most sensitive settings
Charlestown's harbour and the streets around it form a Grade II* listed conservation area, familiar to most from its use in period drama filming. Any exterior change here matters more than it would elsewhere, and homeowners are right to be cautious about swapping an original-looking door for something that reads as obviously modern. The good news is that composite doors, properly specified, are one of the few upgrades that can go in without compromising the setting.
Getting the panel detail right
For Charlestown properties we generally recommend a traditional six-panel composite door with proper moulded bead detail and, where the original had one, a fanlight above. From the street, a well-specified composite door in the right heritage colour is very difficult to distinguish from the timber original it's replacing — which is exactly the point in a setting this closely watched.
Colours accepted in the conservation area
Black, Chartwell Green and Cream are the colours we most commonly fit in Charlestown, and all three sit within the range typically accepted in Cornwall's conservation areas — though we'd always recommend checking the specific policy for your street before committing, since conservation guidance can vary block by block.
Modern security behind a period face
None of the heritage styling changes what's happening structurally — every doorset we fit in Charlestown is PAS24 tested as a complete assembly, with a multipoint lock and 3-star cylinder, giving harbourfront properties a genuine security upgrade that's invisible from the street.
