Mousehall, Carrowmullan,

Mousehall is a rare opportunity to acquire a period house on just under 5 acres of stunning waterfront grounds in Fahan, Co. Donegal—an area long considered “The Hamptons of Donegal” and the most prestigious coastal address in the region.

This distinctive late 1930s residence enjoys exceptional privacy, panoramic views over Lough Swilly, and direct foreshore access via a 156ft jetty on a 99-year lease dating from 1947. Originally constructed using stone and features from the historic Glengollan Estate, Mousehall combines heritage charm with coastal elegance. The property is not listed but is recognised by the National Inventory of Architectural Heritage for its architectural value and setting.

The grounds are extensive, beautifully mature, and offer significant development potential, subject to planning permission. There is scope to build a new, larger residence on site—retaining Mousehall as a guesthouse or secondary dwelling—or to develop a small number of luxury homes, all while preserving the property's serenity, views, and status.

This was the lifelong home of Caroline Dickson, one of Ireland’s most respected female architects, who served as diocesan architect for Derry and Raphoe for over four decades. Her connection adds depth to a home already rich in provenance.

Location & Lifestyle

Fahan is loved for its golden beaches, coastal walks, fine dining & marina. It is a destination of choice for discerning buyers from Derry, Belfast, Dublin, and London. Commuting is convenient:

Whether you are seeking an exclusive coastal retreat, a multi-generational estate, or a development opportunity in a truly exceptional location, Mousehall offers it all.
