Why Buyers Love One National Harbor

One National Harbor combines the convenience of condominium living with an active waterfront location.

That walkability distinguishes the building from many suburban condominiums in Prince George’s County.

The building is also appealing because it provides a more complete amenity experience. Residents can enjoy a rooftop pool, fitness center, concierge services, resident gathering spaces, and secured parking while maintaining a lock-and-leave lifestyle. For buyers who want a home close to DC but do not need a detached house or private yard, One National Harbor can offer an attractive balance of convenience and lifestyle.

One National Harbor Condo Features and Floor Plans

Residences at One National Harbor range from efficient one-bedroom homes to larger three-bedroom layouts. One-bedroom homes can work well for buyers seeking a convenient primary residence, a pied-à-terre, or a lower-maintenance home base. Two- and three-bedroom layouts provide more flexibility for guests, home offices, storage, or longer-term living.

Available features depend on the individual home. Buyers should compare square footage, ceiling height, unit orientation, balcony or terrace space, renovation level, kitchen and bath condition, storage, and parking. Higher-floor residences and penthouse homes may offer more expansive views, but every available unit should be evaluated on its own condition, layout, and total ownership costs.
