Situated on a private road along the banks of the Potomac River is 90 River Birch Drive, a custom home by Great Falls Construction - diligently modernized throughout the years. Sited on over 5.5 blissful acres adjacent to the scenic vistas of Riverbend Park, the tranquil natural backdrop is complemented by extensive hardscaping and stonework. The home was designed to conform to the contours of the land, enabling gravity flow with supportive drainage. Inside, an expansive foyer introduces a floor plan that is equally generous in proportion and artistry. Detailed architectural archways and Schonbek fixtures are a testament to classic craftsmanship, while formal living and dining rooms, the former with two fireplaces, are an added traditional element. A sunroom and two porches overlooking the rear yard take advantage of the lush panoramas beyond the double-pane windows. The kitchen, masterfully renovated by legendary BOWA Construction and overlooking the rear lawn, boasts quartz countertops and porcelain tile floors. Commercial-grade appliances by Bosch and SubZero and a large pantry complete the space. Conveniently off the kitchen is a recently renovated laundry room enclosed by pocket doors. The grand primary suite on the upper level has a private rear terrace and twin custom walk-in closets. The primary bathroom, also renovated by BOWA, has a separate lounging area. Three additional bedrooms, two of which connect with a jack-and-jill style bathroom, are all ample in scale and finely detailed with crown moldings throughout. The fourth bedroom suite sits atop reinforced steel beams above the garage, making an ideal office. Jerusalem limestone flooring evokes an upscale ambiance throughout the fully finished, multipurpose lower level. A full bar serves the large recreation room, while a den can be repurposed into a bedroom or isolated secondary office. A full bathroom and additional storage space concealed behind custom paneling complete the level. A well, septic, and propane system comprising two 1000-gallon tanks combine to produce a self-sufficient property. Additional systems include complete deer fencing and an elaborate security system with underground vehicle entry monitoring and sensors for every door and window. Expertly constructed, renovated, and situated in a uniquely private location, 90 River Birch Drive is one of Great Falls' best-kept secrets.
