Grappenhall house extensions — questions we're asked
Do I need a Party Wall agreement in Grappenhall?
If the extension sits on or within 3m of a shared boundary — common on the semis and terraces around Thelwall and Appleton — a Party Wall notice is required. We can point you at surveyors we've worked with.
Can you match the brickwork on older Grappenhall homes?
Yes. On period stock around St Wilfrid's Church and the cobbled main street we source reclaimed facings and colour-match mortar so the new wall reads as part of the original elevation, not an obvious add-on.
