Description

Inchmarnock presents an exceptional opportunity to acquire a substantial 661-acre island characterized by its organic farming capabilities and traditional structures, all of which offer significant renovation potential, subject to planning permissions. Nestled off the Isle of Bute and conveniently reachable from Glasgow within two hours, this island spans approximately 2.5 miles in length, featuring around 4.75 miles of diverse coastline that includes rocky shores and tranquil sandy coves. The landscape rises to about 60 meters above sea level, providing stunning panoramic views across the Firth of Clyde. The land is a mix of approximately 102 acres of grass leys, 66 acres of permanent pasture, and 368 acres of rough grazing interspersed with native woodlands. The soil is well-suited for grass production with opportunities for arable cropping, benefiting from the mild climate provided by the Gulf Stream. Significant infrastructure has been established over the past twenty years; all fields are secured for livestock with a robust internal track system facilitating access. The island contains three main building groupings: Northpark, Midpark, and Southpark. Notably, Northpark features a vacant two-storey farmhouse that has not been occupied since 1986 and presents a prime opportunity for transformation into a primary residence or holiday home (subject to planning). The additional buildings at Midpark and Southpark are positioned near local amenities and the slipway, further enhancing their redevelopment possibilities. Infrastructure assets include a general purpose shed approximately 30m x 55m in size, a gravity-fed network water supply, and an operational ferry service that aids transport between Inchmarnock and Bute. Notably convenient access to Rothesay is available via road or ferry; this seaside town offers shops, restaurants, schools, and more. Outdoor enthusiasts will find ample opportunities for sailing and various land-based activities in the surrounding regions. This island provides not only potential as an investment property through its agricultural use but also as a unique residential project amidst breathtaking natural beauty.
