When's the best time to build an extension in the North East?

How the weather, planning timescales and trade demand affect your extension, and when you really need to start if you want it finished for summer.

We get asked this all the time. The honest answer: the best time to build is spring to early autumn, but the best time to start planning is months before that.

Most delays have nothing to do with bricks and mortar. They come from drawings, planning, party wall notices and everyone wanting to start at the same time. Here's how to time it well.

Why the weather matters up here

None of this stops winter building. It just means more weather days, and the programme needs slack built in.

Work backwards from when you want it finished

Say you want a single-storey rear extension finished by summer. Roughly:

Leave it until spring to start thinking about it, and you're likely looking at a late summer or autumn build.

Why winter can still be a good time

Our advice

Plan in autumn and winter, build in spring and summer, and do inside jobs in the dark months. Book your site visit early. It's free, it costs nothing to find out where you stand, and it gets you in the queue before spring.

This is general guidance, not formal advice on your property. Rules change, so we check the current position at the free site visit and handle any applications as part of the job.

Questions we get asked

Straight answers. No jargon.

Can you build an extension in winter?

Yes, with some precautions for concrete and mortar in freezing weather and extra time for weather delays. Internal work is unaffected.

How long before I want it finished should I start planning?

For a summer finish, start in the autumn before. Drawings, planning and party wall notices can take several months together.

What jobs are best done in winter?

Internal ones: kitchens, bathrooms, knock-throughs, rewires, and loft conversions once the roof is watertight.

Is it cheaper to build in winter?

Not automatically, but it's often easier to get a start date, and good planning in winter means no wasted time in spring.
