We work with your team to test costs early, explore alternatives and keep the design ambition in view. Clear information helps you decide what to protect, where to adapt and how to move forward.
A specification is a set of decisions, not a list of line items, and it is worth pricing it that way. When budget pressure arrives, the useful thing is options rather than a red line: what a change would actually save, what it would cost the design, and what it would mean for the programme.
Test the brief, budget and emerging design together, before assumptions become expensive commitments.
Costed options that help the design team protect what matters, rather than simply removing specification until the number works.
Turn the coordinated design into a tender that contractors can price clearly and clients can compare properly.
Keep cost, change, programme and contractual decisions controlled once the design moves onto site. These are client appointments, delivered in collaboration with the architect or designer.



Mapped against the RIBA Plan of Work. Tendering and procurement are woven into the stages where they actually happen, since their timing depends on the procurement route rather than a fixed point in the design programme.
Testing whether the brief and budget are realistic before the project is committed to.
Setting an early cost framework against the emerging brief and site information.
Cost planning the concept, so ambition and budget are tested together from the outset.
Refining the cost plan as the design is coordinated across the consultant team.
Detailed cost checks against the technical design, procurement route and tendering strategy.
Tender management where required, then cost control, valuations and change through the build.
Agreeing the final account and closing out retention and defects.
Follow-up support where this is separately agreed with you.
Bringing BPH in at concept or early design development lets the practice show the client a credible, tested budget alongside the design, rather than defending the design later against an unexplained overspend.
Send us the drawings you have and the budget you are working to. We will tell you what the design is likely to cost and where the pressure points sit.
