Design & Build · 25+ Years
Extensions, lofts, refurbishments and fit-outs delivered by a builder with over 25 years on the tools — not a sales office. One team, one standard, from first drawing to final handover.

The Cahill standard
The Cahill Construction Group is led by Declan Cahill — a Manchester builder with over 25 years of hands-on experience. We take on a deliberately limited number of projects at a time, so every job gets the same thing: a tight programme, a clean site, honest pricing and finishes that stand up to scrutiny.
From structural extensions in South Manchester to full commercial fit-outs in the city centre, the standard doesn’t change. It’s our name over the door.

Client feedback
“Declan told us exactly what it would cost, exactly how long it would take — and then did exactly that. You don’t realise how rare that is until you’ve used other builders.”
Sarah & James Whitworth — Extension, Worsley
“The site was spotless every single evening. Neighbours actually commented on it. The finish on the kitchen is better than the showroom we copied it from.”
Claire Donnelly — Kitchen & Refurb, Prestwich
“Our loft went from a dusty attic to the best room in the house. Ten weeks, no drama, and the en-suite is genuinely hotel standard.”
Mark & Rachel Ashworth — Loft, Bramhall
How it works
A straight conversation about what you want, what it’s likely to cost, and whether we’re the right fit. No obligation, no pressure.
Drawings, structural calcs and planning handled with our design partners. You get a detailed, itemised quotation — not a number on the back of a card.
One experienced team, a published programme, and a tidy, safe site. You’ll always know what’s happening this week and what’s happening next.
Snagging walked together, certificates in your hand, building control signed off. We leave when you’re happy — not before.
