Our Story

From Humble Beginnings to Dublin's Leading Construction Company

J&G Conwell Construction was founded in 2000 with a simple mission: to deliver exceptional construction services across Dublin with honesty, integrity, and craftsmanship that stands the test of time. What started as a small team of skilled tradespeople has grown into one of Dublin's most trusted construction companies.

Over the past two decades, we've had the privilege of working on hundreds of projects across Dublin—from commercial construction in the city centre to residential new builds in the suburbs, from period property renovations in Ballsbridge to modern modular homes in Malahide.

Our reputation has been built project by project, client by client. We've never compromised on quality, safety, or customer service. Whether it's a small kitchen renovation or a large-scale commercial fit-out, we bring the same level of professionalism, attention to detail, and commitment to excellence.

"Our success is measured not just in projects completed, but in the relationships we've built and the trust our clients place in us."

— J&G Conwell Construction Team
