House Description

A Peerless Location, originally part of the Blairsden Estate. A "once in a lifetime" offering steeped in local history and encompassing privacy with distant western views. Purchased from the Blair Estate in 1950 by the owner's family and is in two parcels. Circa 1800's farmhouse on 13 acres was used as the estate farm manager's home. Setting is reminiscent of the English countryside, the Cotswolds, with stone walls, a tree lined driveway and open fields. The house has 5 bedrooms, 5-1/2 bathrooms, a living room, library, dining room, kitchen and 6 fireplaces. A 1960's addition by local architect James Jones included bedrooms, baths and an expansive wrap-around loggia, which overlooks the distant hills and sunsets. Period details include wide plank and cork flooring and original wood trim in many rooms. Outbuildings include a portion of the original Blairsden's horse and cow barn and a charming creamery with hand made round brick pillars. European craftsmen-built fieldstone wall borders the scenic driveway. The second parcel, 43 Highland Ave, is a separate 3+ acre property bordering on Blair Dr. It has a cozy 2 bedroom cottage with 2 baths and an office. Its charming eat-in kitchen has a fireplace, a bay window and opens into a comfortable living room. A screened porch overlooks an expansive rear yard and the detached 1 car garage. Cottage is a legal rental. Both properties sold strictly "as is". Taxes and assessments are the sum of both properties.
