Description

Bryntirion is an impressive Grade II* Listed country house nestled in the tranquil landscapes of North Wales. Originally dating back to the late 17th century, this property showcases a wealth of historical charm, particularly through its late Georgian renovations from the early 19th century. The estate has deep historical ties and once served as the residence for the Agent of the Vaynol Estate, which encompasses over 1000 acres of picturesque parkland featuring remarkable structures like an Elizabethan chapel and a cultural landscape rich in history. With over 11,000 square feet of living space, Bryntirion boasts numerous period features, such as sash windows and original fireplaces, alongside five distinct reception rooms including a drawing room and family room. A spacious open-plan kitchen with an Aga sets the stage for modern living while offering potential updates to increase functionality and efficiency. The residential space includes five bedrooms across two upper floors, with a luxurious principal suite complete with a dressing room and ensuite bath. Also included are additional guest accommodations within the annexe and coach house that total more than 4,000 square feet—ideal for generating rental income or accommodating visitors. Surrounded by approximately 29 acres of expansive grounds that adjoin National Trust land, there are ample opportunities for landscaping or developing outbuildings such as barns and stables into viable living spaces or recreational venues. Notably, planning permission is already granted for Grooms Cottage (Ref: C21/1042/25/LL), presenting immediate development potential. The property is located in Y Felinheli, offering essential amenities alongside recreational watersport facilities via its marina. Close proximity to Bangor enhances accessibility to further amenities while providing connections to scenic outdoor experiences in Eryri National Park (Snowdonia) and along Anglesey’s coastline.
