Occupying an idyllic valley setting just half a mile from Port Navas Creek and the sheltered sailing waters of the Helford River, a detached former mill house, providing attractively presented and highly versatile 5/6-bedroomed accommodation, suitable as either a large family home or home with income, set within delightful, private, tree-lined gardens and grounds of approximately 2 acres, with detached office and garage block with planning permission for conversion to a 3-storey annexe.


'Bosanath Mill' (Bosanath means peaceful in Cornish and the mill lives up to the name), is a most attractive, detached and highly individual home with much charm and character, occupying an idyllic setting within its own, surrounding, highly private grounds, bordering unspoilt countryside and within approximately half a mile of Port Navas Creek.

Hidden from the roadside, the property is reached via a sweeping driveway, at the head of which a large parking/turning area leads to the accommodation. On the roadside, a detached block-built double garage, with workshop below, benefits for conversion to a three-storey annexe - to be used for purposes incidental to the enjoyment of 'Bosanath Mill' - Cornwall Council application number: PA15/04932.

The accommodation is beautifully presented throughout and extremely versatile being ideal as, either, a large five/six-bedroomed family home, or, as two 'cottages', following the re-installation of a second kitchen, ideal for those seeking a source of letting income or 'two-family home'.

The grounds are another particular feature of the property and comprise lawns, mature shrub borders, slate pathways and patios, woodland, covered veranda and a fast flowing stream which runs the entire length of the western boundary. An extensive, characterful and extremely adaptable home, in an unspoilt setting in one of south Cornwall's most sought-after areas.


Bosanath Valley lies immediately to the north of Anna Maria and Port Navas Creeks, just over one mile from the centre of the well served village of Mawnan Smith, whose excellent day-to-day amenities include a village stores, thatched public house, doctors surgery, electrical shop, church, hairdressers, garage and highly regarded county primary school. The village of Constantine is approximately three miles distant and is reached via the yachting haven of Port Navas, whose sheltered sailing waters lead directly onto the beautiful Helford River and the sea beyond. Helford Passage, home of the Ferry Boat Inn, is an approximate ten minute drive away; before which are the leisure facilities and golf course at Budock Vean; a short distance after which are the internationally renowned National Trust gardens at Trebah and Glendurgan. The outskirts of the port of Falmouth are approximately five miles distant and the cathedral city of Truro, the county's administrative, retailing, health and educational centre is an approximate thirty/thirty five minute driveway and from where there is a regular main-line rail link to London (Paddington).
