Who actually builds it? Delivery routes, explained

A planning consent is a piece of paper. Turning it into finished homes is a separate job — and the route you choose to build it shapes your cost, your risk and your control.

A planning consent is a piece of paper. Turning it into finished homes is a separate job — and one of the biggest early decisions is how you deliver it, because the route you choose changes your cost, your risk and how much control you keep.

The main routes

There are a handful of ways to build out a scheme, and each trades one thing for another:

A main contractor builds the whole thing under a single contract (usually a JCT). It's the simplest, lowest-hassle route — one firm responsible for the result — but you pay for that certainty in their margin and overheads.

Construction management means you, or a project manager on your behalf, hold the trade packages directly and coordinate them. More control and often better value, but more risk and more to manage — you become the conductor.

Managing it yourself with subcontractors is the hands-on version of that: you cut out the main-contractor margin, but only if you have the experience and the time to run it. Labour-only, where you buy the materials and pay trades for the labour, goes a step further again — real savings and control over the specification, but you carry the procurement and the risk. And partnering with a trusted builder sits in the middle: they deliver, you stay close.

There is no single right answer. It depends on your experience, your appetite for risk, and the scheme itself.

Protect your interests

Whatever route you take, one piece of advice holds: have someone independent checking the work. A clerk of works or a project manager, on your side, inspecting quality and progress, is one of the best-value appointments you can make. It's the difference between catching a problem now and discovering it after handover.

Don't hand your finishes to the builder

A word on interiors, because it's where character and value live. Design for the location, not your own taste — reign in the ego. Be specific: choose the exact products, and don't leave the builder to pick your finishes, or you'll end up with theirs. If you haven't the eye for it, pay someone who has. On our own homes, interiors are specified in detail up front, not treated as an afterthought.

For the curious, a build broadly runs groundworks and foundations, then the superstructure, then the façade, then fit-out, mechanical and electrical services, and landscaping — each with its own trades and its own timing.

This is exactly the territory where we can either build a home ourselves under one accountable team, or — if you have your own builder — act on your side to procure it properly, hold the contract to a price, and check the work. Either way, the aim is a home delivered to plan, not one that drifts. If you're weighing up how to deliver a project, it's worth a conversation before you commit to a route.
