The third way to build your own home

Most people building their own home think they have two choices. Hand the whole thing to a builder on a fixed price and hope the number holds — or take it on yourself and spend eighteen months chasing trades you've never met. Both can work. But there's a third way, and it's the one I've used to deliver schemes for the best part of two decades. It's how developers actually build.

What it actually is

It's called construction management, and the idea is simple. Instead of one contractor pricing the whole job as a sealed lump sum, each trade package is procured separately, in the open. You hold the contracts with the trades and suppliers; a specialist manages the lot for you — the buying, the programme, the quality, the cost. Developers do it in-house because it keeps the control, and the margin, in their own hands. There's no reason a private client building one home can't have exactly the same.

Why it's worth a look

Three things make it work. First, everything is visible — you see the real price of every package, not a number you can't see inside. Second, the savings are yours: come in under on a package and you keep it, rather than watch it vanish into a contractor's margin. Third, and people underestimate this one, you can change your mind. On a fixed-price job every change after you sign is a variation, and variations are where the bill quietly runs away. Construction management is far more forgiving, because the stages overlap.

A bit of the how

In practice it starts with a proper budget. Where there's time, we take the planning information and market-test each trade package — actually going out to trades and suppliers — so you know the genuine range before a spade goes in the ground. From there our interiors team works with you and your architect on layouts and products, and writes a detailed specification, so the choices are the right ones and they're made early.

Then comes the part that saves the most. Design, procurement and construction don't have to run in a rigid line — they can overlap, the way a developer runs a site. So you have a choice: settle the whole budget and specification up front if you'd rather have it all agreed, or get going and finalise the rest as you build. Because we're working together rather than across a fixed-price contract, when a decision comes up we find the best answer between us — and more often than not, bring the cost down rather than up.

The honest bit

It isn't free of risk. Because you hold the contracts, you carry the cost risk as well as the reward — if a package comes in high, that's yours too. The difference is you're never doing it alone: you have someone who has done this many times steering the buying, the programme and the quality, and you watch them do it throughout. Most people tell me the thing they didn't expect was how much they learned — they finish understanding how their own home was actually built.

It isn't for everyone. If what you want is a single fixed number and no further involvement, a design-and-build route will suit you better, and we do that too. But if you want to build the way a developer builds — in the open, with room to adapt — construction management is worth a serious look.

If you're weighing it up, I've written a fuller guide to how it works, or you can see the service itself. Either way, I'm happy to talk it through.
