Two worlds collide: preserved history and modern convenience. Unique Barn Conversion from an historic 230 year-old Pennsylvania stone bank-barn. Cornerstone Barn is listed as a class 2 historic structure (The Thomas Hill Brinton Barn) and is now a one-of-a kind custom-built home which is adjacent to dedicated open space. Essentially new construction in 2007 but loaded with history as this design incorporates the stone wall remains of an 1804 Quaker-Built Barn with the earthen ramp and stone walls fully restored. Extraordinary large scale and elegantly finished w/10 foot ceilings, oversized custom woodwork, large public spaces (foyer, hallways, living spaces) window seats, lighted cupola, weathervane, Andersen wood/fibrex tilt-in windows, 2 high-efficiency HVAC systems, sumptuous Primary Retreat. There is a Secondary Retreat as well that is set apart on a separate level and also features a jumbo bedroom and bath. Description: First floor has an attractive front porch into a large light-filled Foyer, a separate Home Office, Living Room, Dining Room, Family Room and Kitchen w/ breakfast area. Here the flooring is all oak hardwood flooring just sanded and refinished with a light cherry/gunstock stain. Granite tops in the timeless and rich cherry kitchen. Second floor has three bedrooms, two baths and a full-featured laundry room and stairs to the 4th bedroom/suite. The walkout Lower Level is fully finished and brings the living area up to 4,900 sq ft. and includes a full bath plus a Kitchenette and it also has an area that could be utilized as an in-law suite or 5th bedroom. The two-car garage has an extra-wide and extra-tall garage door and an inside entrance to Foyer. Despite all of the space, the home is still a good fit for just a couple because the square footage is spread out over 4 levels and elevator ready (estimates in Docs). Not a huge warehouse home and definitely not a cookie cutter or tract-built house! Ceiling fans and large closets throughout. Live in history but still enjoy a modern and low-maintenance home because it is on a small lot (1/4 ac) and semi-detached (1 Barn but 2 Houses) and inexpensive to maintain. Adjacent open space is mowed and maintained by the Cherry Creek Homeowners' Association (HOA) which is a Conservation Community w/ over 100 acres of open space which includes approx 4 miles of mowed off-road walking trails and 3 miles of upscale neighborhood sidewalks. The HOA fee is $88 mo and includes the open space management & 2x week trash pickup. Thornbury Twp is the Jewel of the Region, a Twp. without 1 traffic light and no (none) real estate taxes (but has a 1% earned wage tax) and very convenient location: less than 3 miles to 5 groceries and 1 mile to Wawa and Giant. Close to nearby historic sites including the Brandywine Battlefield where the 9/11/1777 Revolutionary War Battle was fought and the British soldiers recuperated at this very location on the former farm. Later it was a stop on the Underground Railroad with a hideout room in this very barn. Remarkable for the large cornerstones & the even LARGER IMPRESSION that this home leaves on those that see it. It was built in 2007 in the stone wall remains of the 1804 stone bank barn that was part of the prior farm on this property which was from a William Penn Land Grant to William Brinton in 1684 (great history!) and abuts abundant open space. The semi-detached design keeps the taxes and utility costs low but it seems like a detached home as you live here, even to your guests and delivery men! Home has just undergone a light remodel including sanding and refinishing floors, new HVAC, fresh paint, new appliance, all new carpeting and much more. Seller just installed a new 14 x 12 composite deck off of the breakfast area. Move-in ready, turnkey. See the history in the documents sections and displayed in the home along with items from the archaeological dig on-site.
