With summer getting into full swing, Designing Spaces turns their attention to living comfortably, both inside and outside. First, we visit one home with a new HVAC system that is energy-efficient and cost effective. Then, we introduce one couple looking to buy their first home to a mortgage expert for a tutorial on securing a mortgage. Finally, we stretch out in the sunroom, a new addition to the house that provides a new space that is open and airy.
