Blades Building — a Warrington-based Ltd company covering Great Sankey and the wider Cheshire area. Rated 10/10 on Checkatrade across 36 reviews.

Great Sankey garage conversions — questions we're asked
Do garage conversions in Great Sankey need planning permission?
Internal conversions are usually Permitted Development. Changes to the front elevation — brick infill, new window — can still fall under PD but we always double-check with Warrington Borough Council before starting.
Can you match the front elevation on an estate house in Great Sankey?
Yes. On the estates around Penketh and Westbrook we colour-match brick and mortar so the infill panel doesn't stand out from the neighbouring properties.
Can you convert a detached garage into an annexe in Great Sankey?
Yes — provided plot size and Warrington Borough Council policy allow ancillary residential use. Detached conversions with a WC or shower usually need full plans rather than a notice.
Will the floor be cold?
No — the original slab gets a full insulated build-up (typically 100mm PIR under a floating chipboard deck) so it feels no different underfoot than the rest of the house.
How long does a garage conversion take?
A standard single garage is usually 3–4 weeks from strip-out to finished paintwork. Adding a WC or utility adds around a week for first fix and drainage.
