Historic charm in the heart of Kalorama Triangle

The Knowlton, located at 2227 20th Street NW, is a classic example of early 20th-century architecture in Washington D.C.'s coveted Kalorama Triangle neighborhood. Built in 1923, this four-story brick building houses 54 condominium units, offering residents a blend of historic charm and modern urban living. The structure, with its symmetrical facade and decorative entryway, stands as a testament to the area's rich architectural heritage. Situated in one of D.C.'s most desirable neighborhoods, The Knowlton provides easy access to the vibrant cultural scenes of nearby Adams Morgan and Dupont Circle, while maintaining the residential character that Kalorama is known for.

Versatile layouts with period details and modern updates

The Knowlton offers a range of floor plans to suit various lifestyles, from cozy studios to spacious two-bedroom units. Studios, starting at approximately 500 square feet, provide efficient living spaces perfect for singles or those seeking a pied-à-terre in the city. One-bedroom units range from 455 to 916 square feet, with prices typically between $399,999 and $484,500. These homes often feature generous living areas and updated kitchens, some boasting stainless steel appliances and granite countertops. For those requiring more space, two-bedroom units span from 916 to 1,135 square feet, with recent sales around $610,000. These larger apartments often include separate dining areas and ample closet space, ideal for couples or small families. Many units throughout the building have been thoughtfully renovated while preserving original details like hardwood floors and high ceilings, which lend a sense of character and spaciousness. Regardless of size, most apartments in The Knowlton benefit from an abundance of natural light, thanks to large windows that often provide leafy views of the surrounding neighborhood. Some units feature built-in bookshelves, adding both charm and functionality. Kitchens in updated units may include modern touches like Sharp microwave drawers and Liebherr refrigerators, while bathrooms often showcase classic subway tile and frameless glass showers. Monthly HOA fees range from $400 to $700, covering common area maintenance, exterior building maintenance, heat, water, and building insurance.

Practical amenities for urban living

The Knowlton offers a selection of amenities designed to enhance the urban living experience. A standout feature is the shared parking arrangement, with seven spaces available to residents on a first-come, first-served basis – a rarity in this densely populated area of the city. For cyclists, a dedicated bike room provides secure storage, encouraging eco-friendly transportation options. The building's laundry facilities, located in the basement, offer convenience for residents who prefer not to have in-unit washers and dryers. Each unit is assigned extra storage space, helping to maximize living areas by providing additional room for seasonal items or rarely used belongings. Security is a priority at The Knowlton, with recent upgrades including the installation of security cameras in 2021. The building maintains a secure entry system, providing peace of mind for residents. Regular capital improvements, such as the boiler replacement in 2017 and updates to the cornice, iron security bars, rails, and balconettes in 2023, demonstrate the association's commitment to maintaining and enhancing the property. The Knowlton is both pet-friendly and investor-friendly, with some size restrictions for pets. This policy adds to the building's appeal for a wide range of potential residents and investors. The combination of these practical amenities and services, along with the building's well-maintained common areas, creates a comfortable and convenient living environment in one of D.C.'s most desirable neighborhoods.

This local gem features playgrounds, a basketball court, and a community garden, providing a perfect spot for recreation or relaxation. Culinary enthusiasts will appreciate the diverse dining options within walking distance. Lapis, a modern Afghan bistro, offers a unique dining experience with its homestyle dishes and local ingredients.
