You Need More Space – Not Disrupted Living
You know you need the extension. That part’s decided.
It’s the months of dust, noise, and areas of your home you can’t use.
It’s not knowing exactly how long the disruption will last. It’s wondering whether deadlines will hold or quietly slip without anyone telling you.
Extension projects can feel overwhelming – not because of the build itself, but because there are so many moving parts that need coordinating.
And when that coordination isn’t tight, it’s your daily life that feels the impact.
We Keep Your Extension on Track and Your Disruption to a Minimum
TDB Projects doesn’t just build extensions.
We manage the entire project so your build stays on schedule and your life gets back to normal as quickly as possible.
Mark Howe MCIOB leads every project personally.
Trades are scheduled, coordinated, and accountable to one person.
Materials are procured in advance so nothing stalls.
If anything changes, you hear about it straight away.
That’s what CIOB Chartered project management means in practice – structured delivery, clear timelines, and an extension that finishes when we said it would
