An experienced, independent construction project manager on your side — from your first idea, through a fixed-price plan, to a vetted builder and a well-run build. Start with a low-cost Taster Session about your specific project.
Remote-first · London & surrounding areas · Projects £50,000–£1,000,000
On an extension or major renovation you appoint an architect, an engineer, Building Control, a builder and several suppliers. Each has a defined role — but no one gives you an independent view of the complete picture. That gap is where cost, delay and disputes appear.
Builder quotes that leave out work, hide exclusions and can't be read side by side.
Uncontrolled changes, missing packages and client-supplied items nobody planned for.
Variations, payments and instructions agreed verbally — then disputed later.
Plan Build Extend gives you independent oversight and structured decision support — without the cost of a conventional full-time project manager.
Start with a low-cost Taster Session. You only commit to the next stage once you know exactly what it involves.
A focused conversation about your specific project.
From idea to a fully priced, vetted builder.
We manage your build, week to week.
All prices exclude VAT. Preconstruction Package add-ons (party wall, structural, lighting and more) priced individually. Either party can end the Construction Package with 3 weeks' notice.
Delivered remotely through video calls, secure document sharing and structured trackers — built around the information you and your team provide.
A focused 30–40 minute call about your project — £49, no obligation to continue.
The Preconstruction Package takes your idea through to a fully priced, vetted builder — one fixed fee, agreed upfront.
The Construction Package puts us in as your contract administrator — weekly, so nothing falls through the cracks.
Snagging and support right through to a finished, signed-off project.
A defined scope is part of the service. You always know exactly what you're getting.
For a small fixed fee, get 30–40 minutes with an experienced, independent construction project manager about your specific project. We review your planning application and the site beforehand, then talk through what's ahead — Building Regs, party wall, structural considerations — and give you an honest recommendation on next steps. It's the fastest way to find out what you're really dealing with, before committing to anything more.
