Multiple additions and renovations were made throughout this house. Leader Builders doubled the size of this Winnetka house with a massive two-story addition to the east side. The addition contains the kitchen, family room, mudroom, office and garage on the first floor, and the master suite on the second floor. This was the second project that Leader Builders performed on this house. The first one was a relatively small project, focusing on renovation of the front hall, dining room and power room. A year later, Leader Builders returned to do a massive, whole-house renovation with additions. The original part of the house now makes up only a minority of the entire building. Even the roof structure of the original house was taken down to a second-floor ceiling level and replaced. Designer finishing touches and highly efficient technologies abound. In the renovation process the entire exterior of the house—including siding, trim, roofing and gutters—was replaced. All new custom Marvin windows have been installed.
