Homeowners & Self-Builders

Confidence Before Construction

Spend Smart Money

Plan Smarter. Build Confidently.

Most people only discover the true cost of their project after spending thousands on design and approvals.

At that point, it’s often too late to make changes without major cost or compromise.

PreBuild Cost helps you understand exactly what your project is likely to cost - before you break ground and giving you confidence and control from the very start.

A small investment now can save you from costly surprises later.

Design with Real Cost Awareness

At PreBuild Cost, we help architects, designers, and other trade professionals keep projects aligned with realistic, deliverable budgets. Our detailed cost proposals allow you to guide clients with accurate, data-backed information early in the process - helping prevent redesigns, delays, and late-stage cost surprises.

Bridge the gap between design and delivery with true cost confidence.

How It Works for Homeowners

1. Upload Your Drawings
Send us your existing and proposed plans (floor plans, elevations, and sections). You can also upload photos or short videos showing your current property, garden, or access points - anything that helps us visualise your site accurately.

2. Provide Supporting Details
If available, include your structural engineer’s drawings or calculations. Once we receive your files, we’ll send you a short Fact Finder form to capture details such as:

Specification level (standard / mid / high)
Heating and electrical systems
Kitchen, bathroom, and flooring expectations
Known site constraints or planning conditions

This ensures we’re pricing your actual vision, not generic assumptions.

3. Confirm Scope and Payment

Once we receive your files, we will review the scope of work and send you a short Fact Finder form to capture key details (e.g., desired specification level, expectations for heating/kitchens). We will then confirm the fixed price for our cost proposal and charge payment before commencing the detailed quantity surveying work.

4. We Prepare Your Cost Proposal
Our experienced estimators analyse your project using live UK material and labour rates, including realistic overheads and preliminaries such as site setup, welfare, and management.

5. Review & Discuss
You’ll receive a comprehensive cost proposal - a realistic figure based on the information provided - and a 1-hour Teams call to run through the findings, key cost drivers, and potential savings.

How it works

What You’ll Receive

A professionally prepared cost report
Breakdown by key trades and elements
Overheads and preliminaries included for true build value
Commentary on specification and budget considerations
A Teams review call to clarify every detail

Clear, independent cost intelligence you can trust.

How to Use Your PreBuild Cost Report

Your report isn’t just a number - it’s a tool you can use to make better decisions at every stage:

Budget Validation – check that your project fits your available funds.
Design Development – share with your architect to refine materials and layouts within budget.
Builder Discussions – approach builders with realistic figures to ensure quotes are sensible.
Finance & Planning – present accurate build costs to lenders or investors.
Value Engineering – identify where to save without compromising design.

It’s about understanding what’s achievable - before it costs you more to find out.
