3-season room addition designed and built by Advance Design Studio. Our clients wanted a large entertaining space to complete their backyard oasis, and a 3-season room was the best design solution for their home. The screens can be open or closed for breezy, bug-free outdoor living. The new deck and staircase lead directly to the pool area below, making trips from the kitchen to the pool much easier than before. This addition is located in Huntley, Illinois.
