Description
Offered to the market chain-free, this exceptional detached country residence occupies a private plot of approximately one acre and offers around 2,500 sq ft of beautifully presented accommodation. Combining timeless period character with extensive modern improvements, this unique home enjoys a peaceful semi-rural setting whilst remaining within easy reach of Cardiff, Newport and the M4 motorway.
Originally constructed in 1938 using reclaimed architectural features reputed to have originated from Ruperra Castle, the property is rich in character throughout. Exposed oak beams, solid oak doors, decorative fireplaces, leaded windows and a striking thatched roof combine to create a home of remarkable charm and individuality.
A private five-bar gated entrance opens onto an impressive driveway, setting the tone for the accommodation within. The welcoming reception hall features an elegant turning staircase and provides access to a series of spacious and versatile reception rooms.
The principal lounge is centred around a magnificent inglenook-style fireplace and enjoys views across the gardens, creating a warm and inviting space for relaxing. A beautifully appointed formal dining room offers the perfect setting for entertaining, while a separate study conservatory provides an ideal home office or reading room overlooking the grounds.
At the heart of the home is the impressive 23ft kitchen and breakfast room, extensively upgraded to provide a stylish and practical family space. Featuring quality cabinetry, solid wood work surfaces, a central island, integrated appliances and an Aga range cooker, the kitchen flows seamlessly into the adjoining conservatory, where French doors open onto the private terrace and gardens beyond.
The first floor offers four generous bedrooms, including a superb principal suite complete with a luxurious en-suite bathroom. A beautifully refitted family bathroom serves the remaining bedrooms and features both a separate shower and Jacuzzi bath, finished to an excellent standard.
The property has been comprehensively improved in recent years, including a full rewire, modern gas central heating with Worcester boiler, two contemporary bathrooms, a new cloakroom and underfloor heating to the entrance hall, cloakroom and kitchen, ensuring the home combines traditional character with modern comfort.
Outside, the grounds are a particular highlight. Extending to approximately one acre, they include expansive lawns, mature trees, an orchard, decked entertaining terraces, a summer house, greenhouse, former paddock, chicken run, timber stables, log stores and a variety of useful outbuildings, providing endless opportunities for gardening, keeping animals or simply enjoying the peaceful surroundings.
A substantial double-length garage and extensive private parking further enhance the practicality of the property.
Situated within the highly regarded village of Castleton, the property enjoys a superb balance between rural tranquillity and excellent connectivity. Cardiff, Newport, the A48 and M4 motorway are all within easy reach, while nearby countryside, golf facilities and local amenities make this an exceptional location for family living.
Rarely do homes of this character, scale and setting become available. Combining historic charm, modern convenience and outstanding gardens, this remarkable country home offers an exceptional lifestyle opportunity in one of the area's most desirable locations.
