Welcome to this rare architect-renovated gem on a charming Fairmount block. This spacious end-of-row townhouse masterfully blends 1880s craftsmanship with thoughtful modern design, using salvaged materials throughout to create spaces full of warmth and sustainability while maintaining the integrity of the home's original character. Step through the entry vestibule and into the main level to discover an open-concept layout built for both entertaining and everyday life. You'll be greeted by original heart pine hardwood floors, soaring ceilings and thick period baseboards while burnished clay plaster walls span all three levels. The living room features a custom built-in couch with hidden storage, a TV/movie screen that descends from the ceiling at the touch of a button, and surround sound wiring for optional connection. A built-in cabinet and countertop with beverage refrigerator separate the living room from the dining area, providing a convenient bar and additional storage. The dining room's exposed brick wall with hidden lighting adds instant character. Just beyond is the kitchen, with reconstituted Douglas Fir flooring, a large island breakfast bar, gas cooking, plus plenty of cabinetry and pantry space. To the back of this level is access to a garden as well as a generously sized half bath doubling as a laundry room. The second level offers two light-filled bedrooms and a full bath. A large pocket door leads to a charming Bonus Room with original exposed plaster wall-- the perfect office, den, or reading nook. French doors from this room open into the large front bedroom, showcasing an ornate original built-in armoire - a true nod to the home's 1880s roots. The back Bedroom features cork flooring and plenty of windows for natural light. The updated full bath with tub/shower completes this level. The third-floor addition is anchored by a stunning modern steel staircase with floating oak treads that lead to the private Primary Suite. Oversized windows and skylight flood the high ceiling spaces with light. The spacious front Bedroom includes two large upper and lower closets as well as a custom bookcase to offer ample storage while a built-in front planter spans the wide front window bay providing a beautiful natural view. The en-suite full bath features a spacious walk-in shower, wall-hung toilet and custom-built cabinets. Step outside onto the rooftop deck and take in sweeping views of downtown Philadelphia - the perfect front-row seat for city fireworks and sunsets. The newly painted and well-lit basement provides ample clean space offering storage and lots of potential. Modern efficiency runs throughout the home, with 14 solar panels supplying all required annual electrical, new (2025) mini-split AC/hyper-heat system, energy-efficient windows, closed cell roof and wall spray insulation, led recessed dimmable lighting, natural gas for heat with European wall-hung hydronic radiators, gas dryer and a new gas stove, making this home as practical as it is beautiful. Move-in ready and ideally located near neighborhood parks, museums, restaurants and amenities - all within the highly sought-after Bache-Martin school catchment.
