What we typically specify for Warrington jobs
Warrington house extensions — questions we're asked
Do you handle the structural steelwork yourself?
Yes — we install RSJs and pad-stones in-house so the shell doesn't wait on a separate steel contractor showing up.
Do I need planning permission for an extension in Warrington?
Many single-storey rear extensions in Warrington (WA1) fall under Permitted Development, but Warrington Borough Council treats conservation areas, Article 4 zones and larger two-storey work differently. We'll tell you honestly on the first visit which route your project needs.
Can you match the brickwork on older Warrington homes?
Yes. On period stock around Bank Quay and the Golden Gates we source reclaimed facings and colour-match mortar so the new wall reads as part of the original elevation, not an obvious add-on.
Do I need a Party Wall agreement in Warrington?
If the extension sits on or within 3m of a shared boundary — common on the semis and terraces around Latchford and Padgate — a Party Wall notice is required. We can point you at surveyors we've worked with.
How long does a typical extension take in Warrington?
A single-storey rear extension on the kind of property common around Warrington — victorian terraces, 1930s semis and modern estates — usually runs 10–14 weeks on site once foundations start. Two-storey work adds roughly 4–6 weeks.
