A magnificent find in the popular community of Grist Mill Run in Towamencin Township. This cul-de-sac home has been wonderfully maintained and upgraded with custom additions and top-of-the-line materials. Exotic Royal Mahogany (Andiroba) hardwood floors extend throughout the foyer, dining room, kitchen, and rear hallway. The kitchen has been meticulously remodeled with 42" Aston Black solid maple cabinets glazed in a rich antique white with dovetail construction, soft close hinges, and multiple pull-out pantry shelves. The large center island provides a contrasting ebony finish. The Miele dishwasher and built-in Sub-Zero refrigerator have custom cabinet facing, while the GE 5-burner stove offers dual convection ovens and a stunning copper range hood. The kitchen also offers upper level granite countertops, tile backsplash, microwave drawer, under-cabinet lighting, and glass bowl pendant lights over the island. A gorgeous and expansive R-33 rated 4-season sunroom was added to the home with glass French doors from the kitchen and family room, a custom stone accent wall, 18" ceramic diagonal tile flooring, built-in speakers, 9' ceilings, and walls of Argon gas Pella windows with overhead transoms. The sunroom leads to a stunning EP Henry patio surrounded with low-rise walls, pillars, steps and lighted brick and paver walkways around the home. A private and serene rear yard backs to wooded township open space and features a working water fountain with spotlight. Above the sunroom is a maintenance-free 25'x14' sun deck overlooking the rear yard. Back inside, the family room offers a brick hearth fireplace with an exterior air supply for energy efficiency and opens to the kitchen, sunroom, and living room. A single French door separates the kitchen from the powder room, an enlarged laundry room with wash sink, patio access, and access to an oversized 2-car garage. The master bedroom suite offers a double door entry, walk-in closet, separate vanity area, and full bath with updated fixtures, soaking tub, walk-in shower with seamless glass door, linen closet, and skylight. Three other nicely sized bedrooms (one with sun deck access) and a hall bath complete the 2nd level. The majority of the basement is clean, dry and provides terrific storage space. Finally, discover the "secret" room built under the sunroom addition and finished into the perfect "man cave" with outside egress. This home must be seen to be appreciated.
