Scottish island complete with 'true sense of seclusion' comes up for auction

Mullagrach Island, the northernmost of the Summer Isles, spans approximately 88.7 acres and sits at the mouth of Loch Broom.

It was previously owned by London-based lawyer turned conservationist, Steve Brown, who put the island up for sale for £500,000 in 2024.

Mullagrach is on the market once again and will be sold by Savills on June 9, with bids starting at £350,000 and a “true sense of seclusion” included in the final price.

Mhairi Archibald, associate director of Savills Auctions, said: “We’re seeing good levels of demand for truly unique assets coming to auction, and private islands often capture the imagination. The sale of Mullagrach presents a compelling opportunity for buyers seeking something genuinely rare.

“With its scale, setting and ready-to-enjoy accommodation, we expect significant interest ahead of the sale.”

Set within the Wester Ross Marine Protected Area and forming part of Scotland’s first UNESCO Geopark, the island combines remarkable natural beauty with significant environmental importance, Savills said.

The buyer will be the custodian of a landscape of heather, wildflowers and rough grassland - plus a variety of rocky beaches, sheltered coves, caves and dramatic cliffs.

Savills said the low-impact cabin blends “seamlessly into its surroundings” with a curved , heather-clad roof.

The agent described the interior of the off-grid cabin, which was built in Switzerland, as “both practical and atmospheric” and features a kitchen, a wood-burning stove and two box beds.

Power is supplied by solar panels with rainwater harvesting and composting systems making it a “truly self-sufficient escape”.

“ The cabin is to be sold with its contents, ready for overnight and longer stays,” the agent said.

The island is accessed from harbours at Ullapool and Old Dornie with Mullagrach having its own dedicated landing stage and mooring.

Iona Conn, Associate Director, Savills Residential, adds: “Private islands offer a unique sense of peace and connection to the landscape, and opportunities to acquire them remain limited. Mullagrach is particularly appealing in combining that sense of seclusion with a setting that is both accessible and ready to enjoy.”

Mullagarach is the latest of the Summer Isles to come on the market.

Last May, a businessman fulfilled a “lifelong dream” by buying an island to to set up a centre on its shores to help save Scotland’s seabirds.

Robert Graham, of Moffat in the Borders, became the owner of Càrn Deas in the Summer Isles, which spans 22 acres.

Mr Graham, who is understood to have headed up an IT company, applied to Highland Council to create a bird observatory and education centre on the island far from the “constantly connected world”.

Meanwhile, financier and philanthropist Ian Wace bought Tanera Mor in 2017 and handed it over to a trust, which now uses the island as a retreat for the charities it supports.

Restoration of buildings on the island, whose prosperity was traditionally built on the herring trade, has been completed.

Summer Isles Enterprises, which manages Tanera Mor, has since bought up land and property around Achiltibuie as well as the Summer Isles Hotel, which is currently being renovated.

In October 2024, Mr Wace gave £1.75m to a community trust to help it buy up around 8,000 acres of the Coigach peninsula.
