For those seeking a radical departure from urban life, a rare opportunity has emerged off Scotland's rugged northwest coast. Mullagrach Island, an 88-acre outcrop in the remote Summer Isles archipelago, is heading to auction with a guide price of £350,000 (approximately €405,000) — less than the average cost of a home in many parts of the United Kingdom.
The property, listed by Savills and set to go under the hammer on 9 June, includes a solar-powered cabin, making it a turnkey off-grid retreat. The island is the northernmost in the Summer Isles, accessible only by boat from Ullapool or Old Dornie on the mainland, or by helicopter for those with deeper pockets.
Wilderness and Self-Sufficiency
Mullagrach is exceptionally remote, even by Scottish standards. Its 88.7 acres feature beaches, cliffs, caves, and coves, covered in grasses and wildflowers during spring and summer. The surrounding waters host seals, dolphins, otters, greylag geese, and occasionally rare minke whales. The island is part of Scotland's first UNESCO geopark, underscoring its natural significance.
The existing cabin, though small, is well-equipped. Its wooden structure, topped with a heather-clad roof, includes floor-to-ceiling windows offering panoramic views. Inside, there is a kitchen and dining area, two box beds, a wood-burning stove, solar panels for electricity, and a composting WC outside. A rainwater collection system is in place, though drinking water must be brought in bottles.
This level of self-sufficiency is typical of off-grid living, a lifestyle that has gained traction across Europe as more people seek alternatives to crowded cities. For context, similar opportunities have appeared elsewhere: Greek Island Makri Up for Auction at €247,000, but Development Strictly Limited.
The island's isolation means residents must be prepared for harsh weather and limited connectivity. Yet for those willing to embrace the challenge, the reward is complete solitude in one of Europe's most dramatic landscapes. The cabin's design prioritizes simplicity and integration with the environment, a philosophy echoed in other European off-grid projects.
Scotland's Summer Isles are part of a broader trend of remote island sales across Europe, from the Croatian truffle towns to Italian lake islands. However, Mullagrach stands out for its affordability relative to mainland property prices. The guide price of £350,000 is below the UK average house price, which hovered around £285,000 in early 2025, though regional variations are significant.
Potential buyers should note that the island's infrastructure is minimal. There is no mains water, sewage, or grid electricity. The solar panels provide limited power, and the composting toilet requires regular maintenance. Access is weather-dependent, and supplies must be brought by boat or air. These factors make it unsuitable for those seeking convenience, but ideal for adventurers or conservationists.
Savills has marketed the island as a “rare chance to own an off-grid escape in one of the country's most spectacular natural settings.” The auction date is set for 9 June, with bids expected from across Europe and beyond. Given the growing interest in sustainable living and remote properties, Mullagrach could attract a diverse range of buyers, from eco-enthusiasts to investors looking for a unique asset.
For those inspired by such a lifestyle, other European islands offer similar opportunities. For instance, Live Rent-Free on a Greek Island by Caring for Its Feral Cats provides a different kind of off-grid experience. Meanwhile, the challenges of remote living are highlighted by stories like Greek Island Hospitals Face Critical Staff Shortages, Union Warns, reminding us that isolation has its downsides.
Ultimately, Mullagrach Island represents a bet on self-reliance and a deep connection to nature. Whether it becomes a permanent home or a seasonal retreat, its sale will be a testament to the enduring appeal of Europe's wildest corners.
