Welcome to 21677 N Sylvander Drive in Deer Park. This is a fantastic, sprawling late-century modern Executive ranch on a quiet street designed & built by Mitch Tarzian. Featuring beautiful materials such as brick, cedar, stone boulders, vast expanses of glass and travertine floors plus a spacious, open floor plan that includes a sunken living room, sunken Primary Suite, floor to ceiling stone walls & fireplaces, indoor planters and so much more. The Primary Suite features an enormous dual en-suite bath with two walk-in closets, tub, shower, two private water closets and tons of cabinet & counter space. In addition to bedrooms 2 & 3 is a 4th bedroom with its own en-suite that can be used as a guest suite, in-law suite or separate home office. Multiple living spaces include the sunken living room with two-sided stone fireplace with the family room on the other side, as well as the dining room, expansive kitchen with eat-in area, and a screened porch leading to a large deck. Numerous skylights add to the natural light afforded by the huge windows throughout the house. Many of the home's details are original so that you can live in it as-designed, or update to your preferences. All day-to-day needs are on the main level including a spacious laundry / mud room, so this beautiful house lives as a true ranch. There's even a 3 car garage, and a substantial partial basement with tons of storage space, and all of this high up on a hill on a beautiful lot of over 2 acres surrounded by mature trees! A vast, curving driveway has plenty of space for more than a dozen vehicles. Being close to both Barrington and Lake Zurich makes for an excellent and special place to call home. Many recent updates & improvements, including a new roof in 2022, new HVAC systems in 2022, new well equipment in 2022, as well as a freshly seal coated driveaway, extensive landscaping cleanup in recent months, exterior fascia replacements / repainted and more.
