Building Design Services in Sagaponack, NY

“We used Cornerstone to design our new home after a fire. Lisa was great at listening to what we wanted and provided quick turn around on updates and changes. She was as qualified as any architect we interviewed and I was sold when one of the builders I interviewed said she corrected architect plans when we needed to get them approved by the town. I loved working with Lisa and would recommend her to anyone looking at new builds or remodels. She's great...what else can I say.”
