660 Willowbrook Way Here is one coming to you from Milburn Estates in O'Fallon. The subdivision currently has one entrance and is located just south of the Milburn High School Campus. This split foyer ranch is well taken care of and sits on one of the larger more desirable 0.40 acre lots towards the back of the subdivision. It is around 2000 sq ft on the main level. Due to the welcoming addition of turning the back covered patio into a four seasons room since last time on market. It has its own mini-split system to help get the most use out of it all year long. Plus added a new patio area for when you want to sit outside and enjoy this backyard view. Three car attached garage, 4 bedrooms, 3 baths, & around 900 more finished sq ft in the basement helps give this property the "Let's go see this one in person" vibe. Primary main floor suite has a great flow to it. The +/- 7'x14' walk in closet can be entered from the bedroom and the bathroom is a great perk. Adjoining kitchen, dining, & living helps give that open feeling that a lot of buyers are looking for. Downstairs is around half finished. Leaving plenty of space for storage and utilities or adding some more sq ft if needed. It is also home to the 4th bedroom and has a full bath. Left side of the home landscaping has been used for gardening with an extra row of blocks added to help make maintenance work less of a hassle. New roof in 2025, washer & dryer 2024, whole house humidifier 2024, & new garage door motors and hardware help take future expenses off of your list.
