House Extensions in Eastham
Eastham is a village on the southern tip of the Wirral peninsula with a genuine village character, good motorway access, and an active community of residents who invest in their properties over the long term. Projects here often aim for a quality that respects the character of the surroundings rather than simply maximising square footage.
What to expect building in Eastham
Eastham sits adjacent to Eastham Country Park and parts of the village boundary are near SSSI-designated land and the greenbelt. This does not typically prevent extensions to main dwellings but can affect outbuilding projects and development close to field boundaries. The village character is valued by residents, so we take care with materials and design on any extension that is visible from the street or public space, aiming to complement rather than contrast with the existing character of the building.
Typical housing stock in Eastham
Properties in Eastham range from older village-era houses on Old Hall Road and Eastham Village Road to Victorian semi-detached housing in the established residential streets and newer private estate homes on the village outskirts. Plot sizes in Eastham tend to be on the generous side compared to the denser Wirral suburbs.

Larger single-storey extensions of up to 6 metres or 8 metres may be possible under the Prior Approval scheme.

Questions About House Extensions in Eastham
Do I need planning permission for a house extension in Eastham?
Eastham Village Conservation Area covers the historic village core. Properties within or immediately adjacent to the conservation boundary should verify their permitted development position with Wirral Council. Standard PD rules apply to the wider residential streets outside the conservation area. In general, single-storey rear extensions within the standard Permitted Development limits do not require a planning application to Wirral Council. The limit is 3 metres for semi-detached and terraced houses and 4 metres for detached houses. Larger extensions under the Prior Approval scheme may also be available depending on your specific property and location. We confirm the exact position before any work begins.
How much does a house extension cost in Eastham?
Costs in Eastham vary depending on the size, type, and specification of the project. A single-storey rear extension typically starts from around £1,500 to £2,000 per square metre for a well-built, fully insulated extension. CNR Construction provides a detailed fixed-price written quote before work starts, so you know the full cost upfront with no surprises.
How long does a house extension take to build in Eastham?
A single-storey rear extension typically takes 8 to 14 weeks on site once work begins. A double-storey extension may take 12 to 20 weeks depending on scope. We agree a programme before starting and keep you updated at every stage.
