The Baldwin Estate is truly picturesque, this historic home on grounds just shy of 12 acres formally known as Rose Tree Farm in Baldwin's Corner just outside Pennington Borough, has been admired by locals and visitors for years. This stately home offers plenty of living space for today's bustling households. The foyer welcomes you to the home's beauty with original detailed moldings, paneled doors, marble mantle surround fireplace, oak floors and grand formal rooms with high ceilings and large, large wavy glass windows. A spacious formal dining room with paneled wainscoting and paneled doors lead out into the hallway and kitchen area. The cozy family room features a brick fireplace with an original vintage Mercer tile inlay, flanked by mahogany custom cabinets and a wall of glass opens to a year-round sunroom/solarium having marble flooring with picturesque views of the fully stocked, stream-fed lake on the property. The large modern kitchen and breakfast area is adjacent to a big mudroom that leads out to a brick patio and the pool. The upper floor rooms offer great flexibility with four large bedrooms, all having lots of natural light and hardwood flooring, including a multi-room main bedroom suite with a tiled bathroom and sitting room with a wall of closets. On the grounds are multiple paddocks and pastures, riding ring, that back to trails and Curlis Lake Park, an in-ground pool, tennis court, pool house and barn with a tack room, hayloft or storage area, and several outbuildings. A convenient open garage sits adjacent to the main house. In need of some updating, this idyllic home and grounds are unrivaled, unlike anything on the market in the area today, and will surely shine with a little attention. Just minutes into the charming Boro of Pennington. This property is in the vicinity of the Trenton Mercer Airport and could be in their fly zone.
