House Extensions in Upton
Upton is a well-connected suburban area in central Wirral, close to Arrowe Park and within easy reach of the Mersey tunnels and Wirral Line stations. CNR Construction has completed multiple projects in Upton, including a side extension where the ground conditions required specialist mini piling before the main structure could go up.
What to expect building in Upton
CNR's experience in Upton includes a side extension where ground investigation revealed variable made ground requiring mini piling before blockwork could begin. This is not unusual in some parts of Upton where old field boundaries and historical infill can create uneven bearing conditions. We include a brief ground assessment as part of every initial site visit in this area so we can flag any requirement for specialist foundations in the quote rather than as a surprise during the build.
Typical housing stock in Upton
Post-war semi-detached and detached properties make up the main residential areas around Arrowe Park Road, Moreton Road, and Woodchurch Road. Some more modern private estate housing sits on the eastern side of Upton. Most plots are of a similar depth to the interwar housing in Moreton, giving practical space for single-storey rear extensions.

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 Upton?
Costs in Upton vary depending on the size, type, and specification of the project.
