Description
HEAVENLY AT THE HARPER: Upgraded, Big, Bright, Beautiful 3BR 2.5BTH w/Treeline Views, Custom Closets & Private Balcony NEW FULL SERVICE CONDO BUILDING: Roof Deck, Grilling Station, Play Rooms, Art Room, Podcasting Studio, Music Studio, Game Room w/Screening Area & Billiards, Pet Spa & More Here is a surprising new condo home on the treetops, with green, tree-top views from every single oversized window and its own private balcony. Light and quiet, this stretch-out, winsome North and South facer is a stellar standout on the treasured treeline of the new and beloved Harper. Above ceilings rise nearly ten feet -- underfoot are wide-plank White Oak floors -- and everywhere you look is leafy, lively, light, and lovely. This upgraded vibrant abode -- in a supreme location -- has it all. With a lovable, verdant perch in its famously well-run, well-served, impressively amenitized building, here's the handsome, move-in ready home for which you've been looking -- bigger, better, balconied, and more beautiful than ever. The sizable foyer hall is an ideal gallery -- welcoming you and guiding you to the big living/dining room. This is the comfortable, lovable heart of this home - a large entertaining space anchored by oversized picture windows onto the tree-line. Open to the eat-in chef's kitchen, this great room is built for a big stretch-out life. The cook’s kitchen is a well planned culinary delight created by Poliform & ODA. With ample Taj Mahal quartzite countertops and custom lacquer cabinetry (with antique brass Waterworks hardware), and a top-tier suite of Miele appliances (including wine fridge), this gorgeous kitchen is fabulous and functional. The graceful residential hall graciously separates the entertaining rooms from the bedroom suites. The expansive, king-sized primary suite also enjoys grand picture windows with leafy tree views, and boasts its own private tree-line balcony with leafy garden views. Here, sunrise coffees give way to starlight drinks -- all from your own, intimate al fresco perch. There is an immense, designer-outfitted, primary walk-in closet with vanity space, and an overscaled, primary bath. Graced by Crema Luna limestone and Namibia white marble, the spa-like primary bath offers radiant heated floors, dual sinks, a soaking tub, a step-in shower, and Waterworks fixtures. This primary suite is a masterful retreat. Both large guest bedrooms are bright South-facers, flexibly fine and comfy with good built-out closets, pristine and peaceful, and are served by their own full limestone bath (with dual sinks and tub-shower). This well-planned, sophisticated, luxe residence — with its lovely powder room, abundant, designer closets, en suite side-by-side washer and dryer, big solid-core doors, Valli & Valli hardware, and high-efficiency VRF central air/heating -- offers year-round comfort, magnificent space, and a forever lovable vibe. Well designed by the award-winning firm ODA Architecture, The limestone clad Harper is one of the Upper East Side's newest, premier, full-service condominiums. A celebrated address, residents are well served by an attentive, round-the-clock staff and beloved resident manager. Famous for its top-tier amenities, Harper life is easy, fun and convenient.
