Founded in 1991, Castlethorn Construction is one of Ireland’s most successful residential and commercial developers. Over the past three decades, Castlethorn Construction has developed a well-earned reputation for exceptional quality craftsmanship. We passionately believe that the final verdict on our developments can only be passed when the entire project has been completed and when our new homes become new communities. Our quest for perfection involves not just the actual units that we build, but the complementary quality of the landscaping and overall finishing which typifies a Castlethorn development. We also believe that quality is apparent in the selection of our sites. We continue to provide homes in areas which are rich in physical and social amenities and which reflect the needs of today’s homeowners, whether they be young singles, ‘empty nesters’ or families.
