Building Estimator Services for Homeowners
Clear budgets before you commit
Planning an extension, loft conversion, refurbishment, or new build and want certainty on costs? Our Building Estimator Services give homeowners a clear, realistic breakdown of likely build costs early in the process, so you can make confident decisions.
What a building estimator does, and why it matters to you
A building estimator translates your project drawings and requirements into a practical, itemised cost plan. For homeowners this means no surprises, better decisions, and more control over the scope of work.
Our estimators assess the design, quantify materials and labour, allow for site conditions, and provide a transparent cost breakdown so you know where your money is going.
Our Building Estimator Services, tailored for residential projects
We focus on the practical information homeowners need to move forward with confidence. Typical deliverables include:
​
-
An initial feasibility cost to help shape your brief
-
A detailed cost plan with elemental breakdowns, trade packages, and allowances
-
Provisional sums and recommended contingencies
-
Notes on assumptions, exclusions, and programme impacts
-
Procurement and tender advice if you want to invite builders
Every estimate is tailored to the size and complexity of your project, whether a single room refurbishment, a loft conversion, a rear extension or a complete new build.
How our process works
We keep the process simple and transparent, so you get useful information quickly
​
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. 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.
3. 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.
4. 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.
5. Use Your Report with Confidence.
Your PreBuild Cost proposal is designed to be a decision-making tool, helping you move forward with clarity and control.
You can use your report to:​
-
Validate your budget before committing to final designs
-
Share with architects or engineers to refine drawings
-
Approach builders for quotations with confidence
-
Present verified cost data to banks or lenders

Identify potential savings before the project starts
Confidence before construction - that’s what PreBuild Cost is all about.
