Garage Conversions for Runcorn homeowners
Blades Building — a Warrington-based Ltd company covering Runcorn and the wider Cheshire (Halton) area. Rated 10/10 on Checkatrade across 36 reviews.
New-town expansion sitting next to the older Runcorn village core. That mix matters when you're planning garage conversions — a project on the kind of property near Silver Jubilee Bridge (think new-town estates plus older sandstone terraces) isn't the same job as one on a newer estate off M56 J12 and the Mersey Gateway, and the price and the sequence should reflect that.

Runcorn garage conversions — questions we're asked
Can you convert a detached garage into an annexe in Runcorn?
Yes — provided plot size and Halton 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.
Will I lose off-street parking converting my garage in Runcorn?
Realistically, most homes around Runcorn still have a driveway in front of the garage, so parking usually stays. Halton Borough Council rarely objects unless the property was originally consented with a parking condition.
Can you match the front elevation on an estate house in Runcorn?
Yes. On the estates around Halton and Weston Point we colour-match brick and mortar so the infill panel doesn't stand out from the neighbouring properties.
Do garage conversions in Runcorn 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 Halton Borough Council before starting.
