O' Flaherty Construction, Builder, Palmerstown, Co. Dublin

For Building Work That's Built On Experience

O' Flaherty Construction was founded in 1995 by Pat O' Flaherty to provide a high quality building service to Dublin homes and businesses. Since then, we have successfully completed over 300 building projects including new builds, extensions, renovations, attic conversions, bathroom renovations and porches.

Typically, approximately 50% of our projects are architect designed and managed. We work directly with the homeowner in the remainder of projects. In either case, our priorities are the same - a clear plan, regular communication with all our clients and quality building.

We're very proud of the quality and consistency of our work. We'll be happy to arrange for you to visit previous projects and speak to our previous clients.
