Being first time homebuyers, we found the experience to be remarkably stress free. The agents and builders associated with St. John’s Crossing were professional and friendly. We were also surprised at the speed and efficiency of the building process. There is no doubt in my mind that I would recommend Catalyst Builders to a friend. As a matter of fact, I already have!

Living on Johns Island is wonderful. St. Johns Crossing is a very quiet and peaceful neighborhood and has the rural-type feel being on Johns Island, but yet still 15 minutes to downtown Charleston. The residents in St. Johns crossing are extremely friendly and always willing to help out their neighbors. I’ve had a pleasant experience with Catalyst Builders. They are very tasteful and reasonable at the same time, which is sometimes hard to find in the Charleston real estate market.

I chose to buy in St. Johns Crossing because it is affordable and I love the various lowcountry designs and layouts of the houses. Almost every house has a large front porch which creates a social and friendly neighborhood. I would definitely recommend Catalyst Builders to a friend. They build quality low country style houses at an affordable price point.

Price and location were perfect. Johns Island is a beautiful place and the community is coming into its own as the next Mt. Pleasant in my opinion. The neighborhood is younger and alive with people willing to lend a hand. You really do feel like a part of the St John’s Crossing family when you live here.

St John’s Crossing is centrally located (more than most people probably realize) and a great deal.

My home buying experience was great! I have a difficult work schedule that can make scheduling things during “business” hours tough. Someone was always available to meet with me or answer my questions throughout the entire process. St. Johns Crossing is a great location. You get to enjoy the beautiful surroundings and peacefulness of Johns Island while also being conveniently located to James Island, Kiawah, Downtown, and West Ashley.
