A beautiful addition and renovation complete this Cohasset, Massachusetts home. Lead architect for this project was Heidi Condon from HC Design. JB Sash & Door helped create the expansive and open feel by providing sound recommendations regarding the windows and doors. The windows and doors are all Marvin products and complete the appeal of this home. Renovations included creating a great room complete with kitchen and living area. The new great room has a wall of windows and opens up to the outside via a new french door. The upstairs also boasts hallways of windows that provide endless light.
