Why review early?
Great designs. Same old problems.
Even the best designs can run into buildability issues, unnecessary cost, complex details and performance risks — often discovered too late, when the design is advanced and the project is already moving towards site.
Cost surprises
Details or systems that could potentially be simplified or delivered more cost-effectively.
Programme delays
Unnecessarily complex construction, coordination or sequencing.
Difficult details
Junctions and interfaces that may become awkward or high-risk on site.
Performance risks
Thermal bridges, airtightness and potential building-performance gaps.
Compliance questions
Areas worth reviewing further with Building Control or relevant consultants.
Frustrated clients
Late redesigns, budget pressure and unnecessary strain on the design process.
The best time to solve a problem is before it reaches site.
The Buildability & Performance Review brings an experienced contractor's perspective into the project while there is still time to make intelligent decisions.
The service
The Buildability & Performance Review
Practical insight. Real-world experience. Clear next steps.
Build by Milestone reviews your drawings and relevant specification from a contractor's perspective, looking for risks, opportunities and potential improvements before construction begins.
The objective isn't to redesign the project. It's to help the architect and client understand what may be worth addressing before those decisions become expensive to change.

A second pair of eyes
What are we actually looking for?
This is review and identification. It never replaces the professional design team.
- Structure + build sequence
- Are the proposed construction methods practical and logically sequenced?
- Junctions + details
- Are there details likely to become unnecessarily difficult on site?
- Building fabric
- Are there areas requiring closer attention around insulation continuity, junctions or thermal bridging?
- Airtightness
- Are there interfaces that may make airtightness difficult to execute?
- Windows + doors
- Are openings, interfaces and installation details properly coordinated?
- Services
- Are building services likely to conflict with structure, fabric or finishes?
- Materials + systems
- Are there alternative systems, products or suppliers worth investigating?
- Cost + complexity
- Are there areas where complexity appears to add cost without strengthening the design intent?
- Compliance
- Are there areas the design team should review further with Building Control or relevant consultants?
One real project
£100K+
Potential steel + structural savings identified on one project.
On one project, Build by Milestone identified more than £100,000 of potential savings in steel and structural work — without changing the architectural layout or appearance of the building.
The opportunity came from reconsidering how the design would be constructed, not what had been designed.
Same design.
Smarter construction.
A contractor-side review → £100K+ opportunity identified on one project
This is one genuine project example. Results and opportunities vary from project to project, and no saving is guaranteed.
Collaboration
Your design.
Your client.
Your project.
We're here to help you build it better — not redesign it for you.
The architect remains in control of the project and design. The client remains the architect's client. Build provides contractor-side input.
Our job is to identify practical risks and opportunities early enough for the design team and client to decide what — if anything — should change.
