Heritage You Can Trust. Expertise You Can Count On.
Delivering exceptional projects for over 150 years.
Ellmer is one of London’s most respected construction specialists, delivering high-quality new builds, refurbishments, and fit-outs across the city’s most demanding sectors. From five-star hotels and luxury residences to commercial, retail, and industrial spaces, we bring precision, integrity, and care to every project.
Founded in 1875 and part of Byrne Group since 1977, our heritage is matched by our ability to innovate—blending traditional craftsmanship with modern techniques to deliver spaces that perform as beautifully as they look.
Our Legacy
For over a century and a half, Ellmer has been trusted to deliver projects that shape London’s skyline and preserve its heritage. From the restoration of The Cutty Sark to the creation of landmark hospitality spaces at Twickenham Stadium, our portfolio reflects our ability to work at the highest levels of complexity, quality, and discretion.
Part of the Byrne Group
As part of the Byrne Group, we benefit from the strength, stability, and resources of a wider construction network—while retaining the agility, focus, and personal service of a specialist contractor. This means our clients enjoy the best of both worlds: big-group capability with small-team attention.
What We Stand For
We believe that exceptional results come from a clear vision, strong values, and the right people. Our work is guided by three core values:
- Safety – Protecting our people and everyone around us.
- Integrity – Delivering on our promises and doing what’s right.
- Respect – Valuing every relationship and every contribution.
These principles run through everything we do—on every site, in every meeting, and in every decision.
