Confidence Before Construction
Spend Smart Money
Let’s Get Your Project Costed Properly
Whether you’re a homeowner planning your dream extension or an architect guiding client budgets, PreBuild Cost helps you move forward with clarity and confidence.
We provide accurate, independent cost proposals based on your drawings and information - so you can make well-informed decisions before construction begins.
Simple, transparent, and built around giving you confidence before construction.
How to Get Started
1. Upload Your Drawings - Use the form on this page to upload your drawings – send your existing and proposed plans (PDF or CAD format) together with any supporting files.
2. We Review Your Information – we’ll assess your drawings and confirm the exact fee for your report before any work starts.
3. We Begin Work – once confirmed, our team prepares your cost proposal and arranges your follow-up Teams review.
Contact Us
Our team works digitally with clients across the UK, so wherever your project is based, we can help.
Office Hours
Our office hours are when we’re available to communicate and take calls:
Monday–Friday: 9:00 am – 5:30 pm
(Email enquiries are typically answered within one working day.)
Please note our estimators often work flexibly outside of these hours when preparing reports - so your project continues progressing even when the office is closed.
Important Note
All proposals are prepared individually based on the drawings and information supplied. Pricing and turnaround are confirmed once documentation is reviewed to ensure every report meets our accuracy standards.
We don’t sell quick quotes - we provide real cost intelligence you can rely on.
