Designer Jessica Waks shares how she transformed a lake house stuck in the ’80s into a stylish summer escape. Get her tips for creating a space that will stand the test of time.

Taking cues from the sandy beach, Jessica decorated with a classic blue and white palette. The great room is the showpiece of the home, with magnificent tall ceilings and expansive windows. Jessica created an intimate feel in the grand space with two sitting areas and plush, inviting furniture. In the kitchen, beadboard cabinets add a classic Montauk look. Plenty of seating in the dining area, breakfast nook and outdoor patio encourage large family meals. Upstairs, Jessica added personality to the bedrooms with black and white wallpaper and heirloom furniture.
