With 248 condos, it is also the largest new condominium project currently marketing in the D.C. area.
It joins three other condo buildings at National Harbor, One National Harbor, Fleet Street and Waterfront Street, which all opened when National Harbor was completed a decade ago.
Combined with apartment communities, there are currently about 2,000 residents living at National Harbor.
Condos at The Haven range from one to three-bedrooms with prices ranging from the mid-$200s to mid-$600s.
Peterson Companies said it had already sold 30 of the condo units before officially opening its sales office this past weekend.
Peterson said the units are 10 to 15 percent larger than typical condos in the D.C. area.READ MORE
