What's special

Private front yardPrivate rooftop poolFully reimagined residence

Some homes are simply places to live. The Amber is a place to become. Introducing The Amber — a fully reimagined residence, where luxury is not a finish, it's a philosophy. Thoughtfully renovated in 2021 from top to bottom, this rare offering delivers an experience that few DC properties can match: every floor with its own world, its own quiet. Natural light pours through at every level, shifting through the day like a living element of the design. And when you reach the top? A private rooftop pool awaits, offering sky-high serenity above one of DC's most vibrant neighborhoods. No HOA. Private front yard. Steps from various grocery stores, and numerous amenities offered by city living. This is not just a property. This is a home and a community. The Amber. Curated. Elevated. Unapologetically yours.
