TECHNICAL DESIGN

Planning is secured. This is where schemes either hold their value or start losing it. Contractors price risk — and if your package has gaps, ambiguities or unresolved coordination, they price it in. That cost comes out of your margin.

We take consented designs through to fully coordinated Stage 4 packages. Detailed enough for builders to price accurately on first issue. Coordinated well enough that site queries don't become weekly calls.

What it covers

  • Stage 4 technical drawings and construction details

  • Building regulations application and discharge

  • Material strategy and specification

  • Structural, M&E and specialist consultant coordination

  • Tender package preparation and issue

  • Construction phase support and RFI responses

Right for you if

  • Planning consent is in place and you're preparing for tender

  • You need a complete, gap-free package that contractors can price without assumptions

  • Your previous architect left the scheme under-developed at technical stage

  • You want to protect the design quality that got planning approved

  • You're seeing contractor contingency pricing eating into your return

Considering a project?

A short initial call is often the fastest way to understand what’s possible, and whether we’re the right fit.
