Overview of 49 East 21st Street

49 East 21st Street is a boutique pre-war condominium built in 1906 and converted in 2005, with just 43 units in the heart of the Flatiron District. The intimate building offers full service amenities including a 24 hour doorman, resident manager, and landscaped rooftop terrace complete with BBQ grill and seating. Each residence includes a large private storage unit, and recent building upgrades have refreshed the hallways and common areas.

The loft style residences showcase classic pre-war architecture with soaring 11 to 13 foot beamed ceilings, oversized windows, and wide plank African oak floors. Units typically feature open concept layouts with chef's kitchens equipped with high end appliances from Bosch, Sub-Zero, and Wolf, along with premium finishes like honed lava stone and quartzite countertops. Many apartments boast coveted southern exposures and split bedroom layouts that optimize privacy, with master suites featuring walk in closets and spa like bathrooms adorned with Italian glass mosaics.

Apartment sizes range from approximately 1,280 to over 1,500 square feet, typically configured as one to two bedrooms with many offering flexible bonus spaces for home offices or dens. Common features include in-unit washer/dryers, custom built-ins, and abundant storage throughout. The building's prime location is close to Madison Square Park and iconic dining destinations including Eleven Madison Park, Gramercy Tavern, and Union Square Café, with easy access to major subway lines and the vibrant shopping and cultural offerings of Union Square and Gramercy.

This "converted loft building" offers "nicely finished" apartments in a classic downtown-style setup with "four units per floor." While the "intimate lobby" might be compact, the building delivers authentic loft living with modern touches.
