Once a decade a residence like this comes to the market.  Greylock Mansion is a 25 room 16,500 sq ft, 8 bedroom, 4 full and 4 half bathroom mansion that sits on 7 acres of beautiful land bordering the 1,800 acres of Wissahickon Valley Park.  The tree lined winding driveway leads to a grand circle and covered entrance of this stone masterpiece originally built in 1909 by steel magnate Henry A. Laughlin.  The gorgeous exterior stone was quarried on site to construct this marvel.  The main house stands on a wide terrace with floor footprint sizes between 5,000 and 3,290 square including the walk out basement floor which has usable desirable ceiling heights.  The grand covered entrance opens to the gorgeous marble tiled  floors of the grand hall of the house and gives a clear span view to the other side of the house and it's giant entertaining patio.  The ceiling height, grandeur of the marble tile, the white marble stairs, and the windows everywhere show the pure class of this building and it's potential.  Luxuriously large living and dining rooms flank the exterior patio overlooking the sprawling 3-4 acre front lawn and the views provide great site of the Wissahickon Valley.  Many of these rooms still have original historic details that can and should be highlighted by her next owner.  The nearby carriage house is approximately 4500 sq ft with garage parking and it has an abundance of possibilities from private office space to in-law residence to work shop or more.  What is more good news is that the property taxes are reasonably low because of the conservancy easement on the property.  Enjoy the tree lined abundant land with taxes equivalent to a home much smaller in size.

The manager has listed the unit size as 16581 square feet.
