About Reilly Building

Peter Reilly has been building homes of exceptional quality and style in the Hamptons since 2010. With more than thirty years of experience in all facets of home construction, he is renowned for high caliber craftsmanship, a hands-on approach to each project, and for working very closely with each client. A native of Ireland, Peter immigrated to the U.S. in the early 1980s and established his own masonry business. Eventually progressing to home construction in the Westchester region he then expanded his business to focus on building in the Hamptons. Peter and his wife Yvonne fell in love with the Hamptons more than twenty years ago and long dreamed of building homes in this beautiful coastal community — a dream that was realized nearly a decade ago with the establishment of REILLY BUILDING on the East End. With their two children in tow, the ocean-loving Reilly family loves to spend time at the beach in Southampton, fishing the local waters in Montauk, and enjoying and exploring all that the idyllic Hamptons offers.
