Welcome home to Rosemont Estate - one of Washington County’s finest properties. From the moment you enter the gated pillars and pass through a manicured wooded park, you can feel the stress melt away. You are struck by the privacy and peacefulness. And as the circular driveway delivers you to the brick portico, you realize you are home. This property offers a first floor in-law suite, finished basement and full brick exterior. THIS HOME HAS HAD A PRE-SALE INSPECTION AND ALL ITEMS FROM THE REPORT HAVE BEEN CORRECTED. With over 5,000 square feet of custom quality , carefully crafted by the Joseph F. Devilbiss Construction Company, it is obvious that they don’t build them like this anymore. The oversized brick exterior (front, sides and rear) detailed with a grapevine joint, is a work of art. Andersen windows, custom Hagerstown Kitchen cabinets, a gourmet kitchen by Spicher’s featuring GE Profile and GE Monogram Appliances, granite countertops, a huge custom bow window and custom trim and millwork are just a few of the high end appointments. Be sure to check out the foyer fixture with the custom motorized lift system to raise and lower it for cleaning and light bulb replacement. The home features a first floor in-law suite with a bedroom , full bath, living room and food prep/eating area. The second floor features the primary suite with a recently remodeled bathroom, 3 oversized secondary bedrooms, another full bathroom and a secret storage area. The outdoor living opportunities are exquisite. Relax on the rear deck in the evening, or lounge by the pool and take a dip on a hot summer day. Enjoy the acres of manicured lawn. It is like having your own private resort. The lower level has a theater room and and large recreation room, part of which is currently being used as an office. Located close to the Potomac River/C & O Canal and all the recreational opportunities it offers such as boating, fishing and hiking. Just a short drive to shopping, restaurants and commuter routes. Custom built for the current owner, this is the first time that this estate has been offered for sale. Don't miss out on this amazing opportunity.

Agricultural Rural District
The purpose of this district is to provide for continued farming activity and the many uses that do not require public water and sewerage facilities and which may be more suitably located outside of the urban-type growth of the larger communities of the County. The Agricultural zoning district has been purposely drawn to enclose large blocks of the best soils for intensive agricultural production as well as gently rolling topography for farming. Most of the operating farms as well as the largest block of farmland preserved through the Agricultural Preservation Program is located in this area.
