Builder Partners · Trade rates and referrals

You build it.
We'll handle the drawings, approvals and technical side.

Capital works alongside residential builders across England. When your client needs a survey, planning drawings, a building regulations package or structural calculations, we produce them — at trade rates, on turnarounds that suit a build programme.

No exclusivity. No minimum. No VAT to add.

2. Referral partner — 10% of our fee

Your client needs more than drawings, or wants to deal with us directly. Introduce them, and if they instruct us you receive 10% of our net professional fee.

  • Excludes VAT, statutory fees and disbursements such as council or building control charges
  • Paid once the client has paid us, not on instruction
  • No exclusivity, no minimum number of referrals
  • We tell the homeowner about the arrangement, because they should know

What we produce

  • Measured surveys — existing plans, elevations and sections in PDF and DWG, with a Revit model where you want one
  • Planning drawings and applications — householder, prior approval and lawful development certificates, submitted and followed through with the council
  • Building regulations packages — technical drawings, specification and the fire, thermal, ventilation and drainage information building control expects
  • Structural engineering — calculations and details for beams, padstones, lintels, joists and foundations, coordinated with the drawings rather than bolted on
  • Scope of works and tender information — when a client needs the job properly defined before it is priced

Why builders use us

One team for the whole technical side. Survey, design, planning, building regs and structures come from the same place, so the steel suits the drawings and the drawings suit the application.

We understand what you need to price. Planning drawings aren't enough to build from. When a client asks us to, we produce a scope of works so you can quote accurately and aren't carrying someone else's missing information.

We don't take your client. Referred clients are yours. We do the design and technical work, and say so.

FAQs

Questions about builder partners.

Can't see yours? Ask a designer.

Do you work directly for the builder, or the homeowner?

Either. Tell us which suits the job and we'll invoice accordingly.

Is there paperwork to become a partner?

No. Send us a project and the trade rate applies. For referrals we register the introduction in writing so there's no argument later about who introduced whom.

How do you charge VAT?

We aren't VAT registered, so there's none to add.

What if my client already has planning permission?

That's a common one — we pick up from there with the building regulations package and structural calculations.

Do you do the structural work in-house?

Yes, by qualified structural and civil engineers, coordinated with the drawings.
