When Loi Thai and Tom Troeschel bought their D.C. home in 2008, they immediately began renovating the interior—but not the landscape. "We wanted the garden to complement and extend the views from inside," says Loi. With two streets and a service alley bordering their property, screening for privacy topped their list of goals. At the same time, they didn't want to feel hemmed in by towering wooden fences that closed out the neighborhood. "It didn't seem very friendly," says Loi. Instead, they opted for layers of evergreens with breaks that would frame borrowed views beyond. Echoing the interior's chalky hues ranked a close second.
