Welcome to 4734 Cross Street, a masterpiece of thoughtful design, where modern sustainability meets classic charm. Developed and designed by one of Philadelphias leading sustainable and green building pioneers, Lehmann Homes, this custom-designed carriage house offers a seamless blend of practicality and luxury, tradition and innovation. Every inch of this home was carefully considered, the result of a meticulous collaboration between the builder and seller to craft something truly one-of-a-kind. From the moment you arrive, the attention to detail is clear. A flagstone driveway and lush greenery guide you to the grand entry, where a sunny foyer sets the stage for whats to come. The entry level provides access to an oversized one-car garage, a coat closet, a powder room, a utility room, a sunny patio, and a versatile bonus room with cozy fireplace, perfect for a den or office. Upstairs, the main living level is designed for both everyday life and entertaining. Sunlight floods the space through 12-foot sliding doors, blurring the line between indoors and out. Step onto the deck, where your morning coffee or evening cocktail is best enjoyed surrounded by lush greenery, twinkling lights, and the kind of privacy that makes this feel like an outdoor living room. Inside, the living room is the epitome of refined comfort, featuring a gas fireplace with a stone tile surround, custom built-ins, and dramatic coffered ceilings. The kitchen is, quite literally, the heart of the home, and this one makes a statement. A 10-foot island, striking pendant lights, and a tray ceiling add a touch of elegance, while 42 custom cabinets, leathered quartz countertops, GE Monogram appliances, and a custom inlaid tile backsplash elevate the space to chef-level status. The adjacent dining area easily seats 10 and feels just as suited for an elegant dinner party as it does for takeout night. Custom millwork and a stunning chandelier set the mood, while a pantry and powder room with delightful Martinique-inspired wallpaper round out the floor. Head upstairs through dramatic double doors, and youll find the primary suite, a sun-drenched sanctuary that blends classic design with modern indulgence. The spa-like ensuite bath features double vanities, a freestanding soaking tub, and an oversized glass-enclosed shower with a rainfall showerhead. A separate water closet adds extra privacy. The bedroom itself is a serene retreat with a cozy fireplace, a lovely morning kitchen, and a walk-in closet that feels more like a boutique than a storage space. The fourth floor offers two additional sunny ensuite bedrooms featuring hardwood floors and recessed lighting, stylish as they are functional. And then, theres the rooftop. Spanning the entire footprint of the home, this 16x49-foot outdoor oasis is the kind of space that turns an ordinary evening into something special. With unobstructed views of the city skyline and the rolling hills of Manayunk, youll witness some of the most spectacular sunsets around. The covered Trex deck with recessed lighting and a ceiling fan, is thoughtfully designed to float between two green roofs, which serves to insulate the home while improving air quality and reducing stormwater runoff, a perfect combination of form and function.
