About Special Additions

Custom Construction of a Garage, Sunroom, Screen Room, to name a few! 

The team at Special Additions can provide you with custom construction of a custom garage, sunroom, screen room, or various other structural additions that will blend perfectly with your unique aesthetic tastes and the existing style of your home in North Charleston, James Island, or any nearby city. In everything we do, no matter how large or small the task, we complete the work with superior quality and craftsmanship.

Plus, we use only the finest materials – like extruded aluminum, insulated glass, and durable vinyl – and we will always present every option available to best suit your needs. For example, we can outfit any existing or new custom-built screen room with the innovative Eze Breeze window system, a flexible, vinyl window option that installs into a framed porch. This remarkable 10-millimeter-thick vinyl window system helps keep out rain and other nuisances more effectively than screening, yet it allows for up to 75 percent airflow, so you can still enjoy refreshing breezes and a connection with the outdoors. Best of all, Eze Breeze windows can be installed at significant savings compared to traditional glass windows.
