Feasibility Stage Cost Planning
Get clear, realistic budget guidance for your early stage project, so you can decide whether to proceed, how to phase work, and where to refine scope to meet your goals.
What is Feasibility Stage Cost Planning
Feasibility Stage Cost Planning is early cost advice provided when a project is still at concept or pre‑design. It gives homeowners, architects, builders, and small contractors an initial, evidence based budget that reflects likely construction costs, site constraints and key scope choices.
Why Feasibility Stage Cost Planning matters
Early cost direction reduces risk and saves money further down the line. A reliable feasibility stage cost plan helps you to:
-
Decide whether a project is viable within your budget
-
Explore phased delivery to spread cost and cashflow
-
Prioritise key elements, and identify where scope can be reduced or enhanced
-
Secure funding or lender confidence with realistic budget figures
-
Avoid late stage surprises that drive costly redesign or value engineering
What we deliver
Every project is unique, and we don’t use automated templates or generic databases. Every cost plan is prepared manually to match the drawings, specifications, and details you provide. You will receive:
-
Detailed trade-by-trade cost breakdown
-
Overheads and preliminaries included for realistic totals
-
Commentary explaining allowances and specification assumptions
-
Professional PDF report suitable for use with architects or builders
-
1-hour Teams consultation to review your report and discuss next steps
How we work
Our approach is practical, collaborative, and transparent
​
1. Upload Your Drawings. Securely send us your existing and proposed plans (floor plans, elevations, sections) and any supporting information like site photos or structural drawings.
2. Confirm Scope and Payment. Once we’ve received your files, we will send you a short Fact Finder form to capture project details such as:​
-
Desired specification level (standard / mid / high)
-
Heating, electrical, kitchen and bathroom expectations
-
Site constraints, planning restrictions, or access challenges
This ensures our pricing reflects your actual intentions rather than general assumptions.
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 team - combining 15+ years of on-site build experience with 20–30 years of Quantity Surveying expertise - analyses your files using live UK market rates. We remain completely independent to ensure our figures are neutral and accurate.
4. Receive & Review Your Report. You will receive a detailed PDF report, followed by a 1-hour Teams review with one of our estimators. We will walk you through every line, clarify assumptions, and highlight opportunities to save or reallocate your budget.
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.
