Imagine having more than 3,000 square feet of gracious, SINGLE-LEVEL LIVING -with BAKER PARK just steps from your door and the restaurants, shops, galleries and energy of historic Downtown Frederick an easy walk away. This exceptional PENTHOUSE condominium at 104 Mercer Court offers a rare combination in Frederick: the space and presence of a substantial home with the simplicity of condominium living.......... At approximately 3,050 square feet, this is currently the largest condominium offered for sale in Frederick and one of only three residences occupying the building's fifth floor. Inside, soaring CATHEDRAL CEILINGS, a dramatic PALLADIAN WINDOW and abundant NATURAL LIGHT create an immediate sense of openness. HARDWOOD FLOORS flow through the main living areas, while a striking THREE-SIDED FIREPLACE visually connects the living and dining spaces. Beyond the windows, panoramic views stretch toward the CATOCTIN MOUNTAINS.......... TWO ECLOSED SUNROOMS make those views part of everyday life. Comfortable throughout the year, each is wrapped in casement windows and offers its own personality. One features a vaulted ceiling, half-round window and independent climate control; the other pairs an exposed brick wall with a wet bar-an inviting setting for cocktails, conversation or simply watching the seasons change over the mountains.......... The THOUGHTFULLY DESIGNED FLOOR PLAN includes two spacious primary suites, each with a walk-in closet, private full bath and DIRECT SUNROOM ACCESS. A separate entrance to the bedroom wing provides unusual flexibility for overnight guests, extended family or multigenerational living while maintaining privacy.......... For working from home, reading or pursuing a favorite collection, the LIBRARY is a standout: FLOOR-TO-CEILING SHELVING, French doors and a rolling library ladder that conveys. Additional arched built-ins in the dining area add architectural character and valuable DISPLAY SPACE.......... The kitchen offers GRANITE COUNTERTOPS, soft-close cabinetry, under-cabinet lighting, a wall oven, downdraft cooktop, center island and pantry, while in-unit laundry and private caged storage add everyday convenience.......... And this is where the lifestyle becomes especially appealing. LEAVE THE CAR BEHIND for a walk through Baker Park, continue into Downtown Frederick for dinner, meet friends along Carroll Creek, or simply return home and enjoy the mountain views from your penthouse. When you do drive, ASSIGNED PARKING in the SECURE GARAGE and ample exterior parking are both served by step-free ELEVATOR ACCESS, and the residence itself is entirely one level.......... RECENT IMPROVEMENTS include fresh interior paint, refinished hardwood floors, updated lighting and a high-efficiency heat pump installed in April 2026 with a transferable 10-year warranty.......... The $824 monthly condominium fee includes water, sewer, the condominium master insurance policy, professional management, interior and exterior common-area maintenance, secured entry and access to the private fitness room. Owners typically maintain a separate HO-6 policy.......... For buyers who want generous living space without the upkeep of a single-family home-and who aren't willing to give up location, views or room to entertain-104 Mercer Court offers an uncommon opportunity to live large while enjoying Frederick right outside your door.
