Comfort, warmth, superior craftsmanship, and sylvan splendor: these are the hallmarks of this European Revival mansion that borders Fairmount Park in Chestnut Hill. Designed by Zantzinger, Borie and Medary in 1915, this remakable stone home has been in the same family for 85 years. Scarcely visible from the street and hidden behind eight-foot walls, the house lies at the bottom of a long sloping driveway flanked by banks of viburnum, butterfly bush, and climbing rose. One enters by traversing a 42 foot loggia. Behind the massive oak front door is an elegant entry hall enhanced by unusual wainscoting, hand- rubbed rose-colored walls, and the graceful lines of a curved balustrade. And here your journey is just beginning. Please call Marilou (267-285-0402) for details on full layout. The property also includes a fully renovated one-bedroom, one bath carriage house with two automobile bays, as well as a separate three-car stone garage. There is a small decorative pool and a surrounding patio that overlooks a wide expanse of lawn that extends down to the park.
