Frequently Asked Questions
How quickly will I receive my extension estimate?
Most extension estimates are with you in 24 to 48 hours of you sending the drawings.
What information do I need to provide?
Plans, elevations and a short description of the work. Photos of the existing house help us price making good and matching materials.
Are your extension estimates accurate?
Yes. We measure and price this extension — steels, knock-through, roof, glazing and finishes — not a cost per m² average.
Can you price from sketches or ideas?
Yes. A sketch or a set of photos is enough to start. Your estimator will confirm the scope before the numbers go out.
Do you work with builders of all sizes?
Yes. Sole traders and established firms use the same service, UK wide.
