21 Atlantic Street - truly a one of a kind. A fixture of Rockland's South End for over 100 years, she has seen the neighborhood transform from an industrial working waterfront to a beloved and walkable seaside neighborhood becoming one of the most desirable locations in the Midcoast. At the center of it all is 21 Atlantic with unparalleled, unobstructed views of Rockland Harbor, Camden Hills & Mt Battie, the Rockland Breakwater lighthouse and Penobscot Bay's islands from virtually every inch of the property. Exterior features include an in-ground pool heated by solar a 4-season hot tub, stone fire pit for evening gatherings and a nearly 1000 sf roof deck with views that take your breath away. Step inside to the luxurious and modern improvements thoughtfully designed and woven into the stunning industrial reminders of this building's working class roots. An entirely new custom chef's kitchen is at the center of the main living area with views that are enhanced by brand new enormous custom windows (throughout the house) creating a beautiful sense of light and openness. Also on the first floor is the 'Music Room' complete with a baby grand piano. You can lounge watching your favorite sporting event or movie on the 80' flatscreen and if you're so inclined, mix yourself a cocktail at the built-in wet bar. Up the reimagined modern staircase you find 3 of the 4 bedrooms including the luxurious Primary Bedroom Suite. The 2nd floor is where you gain access to the 'Pool House' section of the home which includes a small kitchen and full bath to service the pool area and also enables this section to become its own breakaway apartment thus creating a 2 unit building. Think private in-law or guest quarters or an income generating short or long term rental unit. The 'Pool House' also features a top floor bedroom with a huge slider to the roof deck and, in our opinion, the best bedroom view in all of Midcoast Maine - literally the 'cherry on top' of this singular property.
