Warrington garage conversions — questions we're asked
Can you convert a detached garage into an annexe in Warrington?
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.
