Those who've grown tired of the cookie-cutter contemporary homes ubiquitous to the current luxury housing market will be awed by this breathtaking stone Colonial mansion that retains much of its timeless original architecture. Built in 1901 as the "Ithan Derlwyn," this stunning estate on 2 picturesque acres boasts exquisite artisan details and true craftsmanship, along with the modern comforts discerning families demand. Beyond the covered entryway, in the gracious reception hall are found decorative moldings, hardwood floors, arched doorways, and one of numerous charming fireplaces enriching the ambience throughout. The grand expansive living room at right with custom built-ins, decorative ceiling moldings, a marble fireplace and multiple seating areas is brightened by large windows and glass French doors leading to the outdoor patio. From here awaits a fireside sitting/family room with beautiful crown moldings and property views, a large elegant dining room with a fireplace and built-in seating, and a light-bathed sunroom that spills out to the blissful pool and patio area. The spacious kitchen with plentiful wood cabinetry, a big center island with a farm sink and huge butler's pantry is the heart of the home with an eat-in area for casual fare. Among the most distinctive features of this classic residence is the dramatic, architecturally-significant main staircase that ascends to the upper levels, above which is an incredible stained-glass skylight. Level two with hardwood floors features 5 sun-filled bedrooms and 2 baths, including the enormous en-suite master with peaceful views, as well as maid's quarters offering 2 smaller rooms and a full bath. Occupying the 3rd story are 4 additional rooms, now used as a billiards room, office, and sitting area/TV room, plus 2 bathrooms and laundry. The versatile layout makes an excellent au-pair or guest suite also with a kitchenette and dining room. The exquisite property includes a koi pond with waterfall, gazebo with outdoor fire pit, and large brick paver patio overlooking the side yard. An attached 2-car garage and excellent location in the award-winning Radnor School District make this home exceptional. Radnor Township has approved Public Sewer. Plans are underway.
