Northwind Build (demo)
Start a project
Building plans spread across a table while someone marks them up

Contact

Send us your plans

Drawings, a sketch or a site plan: upload what you have and an estimator will call you within three working days.

Upload

Tell us about the project

Every set of plans is read by an estimator, not a sales team. We keep your files only as long as we need them to reply.

Call an estimator: 09 000 0000

PDF files up to 10 MB each, three files at most. Not ready to share drawings? A few lines about the site is enough.

So an estimator can call you.

Rough budget
Where are you up to?

PDF only, up to 3 files, 10 MB each. Up to 3 files: JPG, PNG or WebP images, or PDF, up to 10 MB each.

Privacy policy

Your privacy: only our estimators open your files. We delete them after twelve months if we do not work together.

What happens next

From your plans to a first price

  1. We read your plans

    An estimator checks the drawings and notes anything we need to ask.

  2. We call you

    Within three working days, with first thoughts on cost, programme and risks.

  3. A site visit

    If it suits, we visit the site with you before we price the work properly.
