Working in Cleethorpes
Postcode districts we cover around Cleethorpes include DN31, DN32, DN35. We also work in nearby Grimsby (2 miles), Scunthorpe (26 miles), Lincoln (31 miles), Skegness (33 miles).
For homes towards East Riding of Yorkshire, Hull is around 18 miles away. Homes across the East Midlands often have usable side land or a driveway beside the house, which opens up side and wraparound options.
Planning and approvals in Cleethorpes
In England a single-storey rear extension can usually go up to 3 m beyond the original rear wall of a semi-detached or terraced house, or 4 m on a detached house, without a planning application, provided it is no more than 4 m high, keeps eaves to 3 m within 2 m of a boundary and, with other buildings, covers no more than half the land around the original house. The larger home extension prior approval scheme raises those depths to 6 m and 8 m, with neighbours notified and a 42-day decision.
Before any drawing is finalised we check whether the house is listed, in a conservation area or subject to an Article 4 direction.
Building over or within 3 m of a public sewer needs the water company's consent, usually through a build-over agreement, before the foundations go in.
Applications are decided by the local planning authority (your district, borough or unitary council).
What is included
- Foundations, often lighter than masonry
- Fire and acoustic details where needed
- Cladding, render or brick slip finish
- Breathable wall build-up with insulation
Moisture is the enemy of any timber building. We design ventilated cladding cavities, breather membranes and a proper damp-proof course height, and keep the frame dry during construction.

Common questions in Cleethorpes
Can I see a price before committing to anything?
Yes. The guide prices on this page are adjusted for Cleethorpes, and the guide-price tool gives a range for your own size. After the survey you get a written price before anything is agreed.
Do I need building regulations approval in Cleethorpes?
Yes. Almost every extension needs it, whatever the planning route. We prepare the drawings and book the inspections.
Do you cover all of Cleethorpes?
Yes. We cover Cleethorpes and the surrounding parts of Lincolnshire. Site visits are free and there is no obligation.
Is timber frame cheaper than brick?
It is similar overall. The frame can save time on site, but the cladding choice has a big effect on cost. Our guide range is about £1,660 to £3,230 per m² including VAT.
Does a timber frame extension need planning permission?
The same planning rules apply as for any extension. If the cladding looks different from the house, permitted development’s matching-materials condition may mean an application is needed.
