Welcome to this beautifully updated four-level split home offering space, flexibility, and modern convenience. Built in 1965, this mid century modern residence features a functional layout with thoughtful renovations throughout and the rare bonus of an adjacent buildable lot included with the property, both located in the highly desirable Mortonaire subdivision in the northwest pocket of Morton Grove. The main level welcomes you with a bright living room and dining room with southern exposure, an updated kitchen with newer appliances and gourmet range, a bedroom, and a renovated powder room with its original restored Crane sink that is a true MCM gem. Direct access to the attached two and a half car garage adds everyday convenience and plenty of storage. Upstairs, you'll find three comfortably sized bedrooms with new carpeting and an updated full bathroom with heated towel rack and lighted mirror, providing a private retreat for family or guests. The lower level expands the living space with a large recreation room ideal for entertaining or relaxing, along with a fifth office/bedroom and an additional full bathroom perfect for extended living or in-law arrangements. The rare sub-basement level offers even more versatility, featuring a cozy den or media room, plus a dedicated mechanical and laundry area with newer washer and dryer and more storage space. Mechanical and aesthetic updates include dual high-efficiency furnace and A/C systems with humidifiers, newer windows with transferable warranty, updated finishes throughout, modern lighting, custom blinds, refreshed flooring, and a connected smart-home ecosystem featuring Nest thermostats, cameras, video doorbell, smart smoke detection, flood sensors, smart refrigerator, and Yale smart lock. Positioned on a prominent corner setting framed by mature trees, the property is enhanced by LED landscape on an automated astronomical timer. The adjacent lot currently functions as an expansive private yard, presenting a rare blend of outdoor enjoyment today and development potential for the future. This move-in ready home blends classic structure with contemporary upgrades and unique land value, a rare opportunity not to be missed.
