Our Clients

"We have been searching for our dream retirement home in the HHI, Bluffton , Beaufort sc area for many years !!!! We came across a place called Bull Point plantation in seabrook sc and toured a new custom build home by OSP construction and fell in love with it immediately. Feeling like this home would not last long on the market with dove into negations and not too long after we came to an agreement . Mr Gavigan and Stacey Hall opened up communications giving us nearly daily updates with pics ,videos and answered all our many many questions . Being from out town these communications put us at ease and even more excited. The home is a classic coastal style with great attention to details with modern top line finishes . Thx you Billy and Stacy for making our dream come true ! #Billsmafia"- Tom and Kathey 169 Bull Point Dive
