Built in 1885 as a Gilded Age summer retreat, Rock Gate is as well-known and celebrated in Washington as its architect: Ehrick Rossiter. Rossiter's generous rooms graced with restored carved butternut wood panels, walnut and fir floors, delicate turned spindles, alongside arched windows, porches, and turreted and gable roofs, define the Queen Anne shingle-style homes of the period. Updated and reconfigured for the 21st century, this magnificent home contains modern comforts without sacrificing historical significance and charm. Bathed in natural light, the kitchen invites cooking & conversation; a spacious mudroom with built-ins summons summer strolls; and a remodeled primary bath leads to a dressing room that suggests elegant ease. Reinvigoration of the interior also includes fresh paint, stylish wallpaper, and new carpeting. Ten fireplaces grace the 5-6 bedroom home that boasts 5 full baths, 1 powder room, a wine cave, and wide staircases. New boilers, hot water tanks, plumbing, lighting controls, chimney liners, a well pump and water treatment system, and new equipment for the heated gunite saltwater pool aid effortless living. In addition to a new 1-bay detached garage, a separate 3-bay garage with a large walk up loft awaits your vision. Understated landscaping compliments the outcropping of stones for which the house was named, and grounds are enhanced by stone pathways trimmed with greenery. A private rear terrace sits amid a nest of trees that embraces the property.
