When Horn & Co. first visited the site in Vienna, an updated cabin from the 1800s was on site, adjacent to a late-twentieth-century house. The owners were dedicated to preserving the cabin while building their new modern English country house designed by Barnes Vanze Associates. The preservation of the cabin influenced the architecture and was critical to the site plan.

The area around the cabin is referred to as the “Remnant Garden.” Horn & Co established a terrace that felt authentic to the cabin itself: vernacular, even improvised. The landscape design is what Horn & Co imagines was once on the site: an allée of crabapples line the driveway leading to the motor court, and drifts of boxwood and sweetbox line the beds of the front façade. At the pool, a perennial border of iris, daisy, and various herbs offer color during the swimming season, while in more distant beds, deer-resistant plants, such as viburnum and butterfly bush, provide color. Specimen trees, such as Deodar cedar and magnolia, minimize views of neighboring houses.

Her experience included designing exhibits for the Bronx Zoo; developing the ecological program for Fresh Kills Park at New York's Department of City Planning; and designing gardens, estates and parks for Edmund Hollander Landscape Architect and Deborah Nevins Associates. Since founding Horn & Co Jennifer has continued to design luxury landscapes for residences, communities and resorts. She has won two silver awards from the Association of Professional Landscape Designers, her projects have been featured in Home & Design, Northern Virginia Magazine, DC Architecture, Hearth and Home, and the Washington Post.
