Monreith House is a rare Category A Georgian mansion set in c.328 acres of policy grounds, mature woodland and the White Loch of Myrton. The principal house extends over four floors with grand reception rooms, 15 bedrooms and six secondary reception rooms currently presented as six apartments. The estate includes three let cottages providing immediate rental income and substantial amenity woodland and loch frontage that together create multiple commercial and lifestyle opportunities.
The property has strong heritage value and many original 18th–19th century features: high ceilings, plasterwork, a bowed garden elevation, Greek Doric porch and an interior with tapestries and carved shelving. These attributes underpin restorative and hospitality potential—boutique hotel, exclusive hire, or continued apartment-let/long-term-let use—subject to listed-building consent and careful conservation-led investment.
Buyers should note material constraints: Monreith is Category A Listed, which will restrict alterations and add consent costs; parts of the house have disconnected wiring and will require full electrical reinstatement; the EPC rating is F; broadband is very slow; and the property sits in a remote, very deprived area meaning local services and markets are limited. Substantial maintenance and conservation expenditure should be budgeted for.
Value drivers include immediate rental from three cottages, sporting and fishing rights, included timber and mineral rights where owned, and exceptional loch and woodland amenity. The estate’s history and protected designed landscape status add cultural and tourism appeal, while internal subdivision into apartments and cottages offers multiple income streams or phased redevelopment options for an experienced purchaser willing to manage listed-building constraints.
