House Extensions in Greasby
Greasby is one of central Wirral's most consistently popular family areas, held in demand by its village feel, good schools, and the green spaces surrounding it. The majority of the housing stock is mid-20th century and the gap between the original layout and how families want to live today drives a steady stream of extension projects.
What to expect building in Greasby
Greasby sits on elevated ground in central Wirral, which is practically useful: drainage conditions are generally better than in the low-lying coastal areas and groundwork investigations are usually straightforward. Many of the 1930s semis in Greasby have had some form of extension at some point in their history, so working with existing footprints and matching the local brick is a familiar challenge for us. The village centre on Pump Lane has a genuine community character that residents protect, and we always consider the streetscene when designing any extension visible from the road.
Typical housing stock in Greasby
1930s to 1950s semi-detached housing is the main type throughout Greasby, with some detached properties and bungalows on the wider roads around Greasby Road, Pump Lane, and the village centre. Plot sizes are generally better here than in the more urban parts of Wirral, giving good options for rear extensions without significantly reducing the garden.
