Company Profile

Company Profile

Denphi Construction was established in 1990 as a family business. Our goal was to build our reputation on a quality service and let our work advertise for us. Since then we have carried out works in the residential sector including extensions, one off houses and apartments, commercial works for IDA, HSE, OPW, Department of Education and other companies. 25 years on and 714 projects later our goal remains the same.


We really do pride ourselves on quality workmanship and endeavour to reflect this in every type of job we undertake and every call out we receive. The high standard that our customers have come to expect is achieved by employing teams of experienced trades-persons under our direct control; most of these have been part of our company for many years. All our employees have been vetted for quality and expertise and fully understand our expectations and those of our clients.

In addition to providing skilled builders on site, we can offer access to independent specialists such as architects, designers and structural engineers to help add that extra special touch and turn your dreams and ideas into reality.
