Isolated retreat in the Scottish Highlands combines self-sufficient cabin, preserved coastal landscape, and restricted boat access, in an offer linked to the private islands market in Scotland.
A private island in the Summer Isles archipelago, in northwest Scotland, has been put up for auction by Savills with a guide price of 350 thousand pounds, equivalent to about 405 thousand euros and close to R$ 2.3 million, according to the original conversion provided.
Called Mullagrach Island, the property encompasses about 35.9 hectares, a self-sufficient cabin, and access primarily by boat, in a coastal region of the Scottish Highlands.
Located in Wester Ross, Mullagrach is north of the Summer Isles, a group of islands situated south of the Coigach peninsula, on the northwest coast of Scotland.

According to Savills, access can be made from the ports of Ullapool and Old Dornie, in addition to the possibility of arrival by helicopter, with landing facilities and mooring system on the island itself.
The offer includes an entire island with an already installed residential structure for stays, without the characteristics of a conventional urban property or a large-scale real estate development.
On site, there is a single low-impact environmental cabin, surrounded by cliffs, rocky beaches, caves, native vegetation, and waters facing the Minch and the mountains of Skye and Torridon.
What the cabin on the private island is like
Designed for the weather conditions of the Scottish coast, the only residential building on Mullagrach was positioned to integrate with the environment and reduce visual interference in the landscape.
According to the Savills announcement, the cabin was developed by Northwoods Design and features a curved roof covered with heather, a solution described by the real estate agency as part of the adaptation of the construction to the terrain.
Inside, the property has a kitchen and dining area, wood stove, and two box beds, a traditional model where the bed is embedded in a closed or partially closed structure.
The configuration allows for overnight stays and longer stays on the island, maintaining occupancy concentrated in a single residential structure with no expansion mentioned in the sales material.
Off the conventional service grid, the cabin uses solar panels for electricity supply and has a rainwater collection system for part of the property’s needs.
Drinking water, however, must be brought in bottled, while the bathroom is located outside and operates with a composting system, according to information released by Savills.
According to the real estate agency, the cabin will be sold with its internal contents, a condition that allows the buyer to receive the furnished structure as per the package included in the advertisement.
Even with the existing structure, the use of the island depends on planning for transportation, maintenance, potable water supply, and travel subject to the maritime conditions of the region.
Private island auction scheduled for June
Mullagrach Island entered the Savills auction scheduled for June 9, 2026, with a guide price of 350,000 pounds, according to information released by the auction house.
This value serves as an initial reference for the bidding and does not necessarily represent the final sale price, as auctioned properties may receive different bids or may not be sold.
The island had already been listed in 2024 for over 500,000 pounds, according to the specialized publication Country Life, before returning to the market in 2026 in auction format.
With the new sales model, the property began to be offered with a lower guide price and promoted on platforms aimed at buyers interested in unusual properties and rural estates.
In a statement published by the New York Post, Mhairi Archibald, associate director of Savills Auctions, stated that there is demand for unusual assets brought to auction and that private islands tend to attract interest.
The executive also said that the sale of Mullagrach represents an opportunity for buyers seeking a type of property considered rare in the real estate market.
In the same coverage, Iona Conn, associate director of Savills Residential, stated that private islands are often associated with tranquility and connection to the landscape, although such opportunities are limited.
For the Savills representative, Mullagrach stands out by combining isolation, viable access, and already installed accommodation for use, according to the evaluation attributed to the real estate agency itself.
Nature, isolation, and boat access
Besides the cabin, the island is described by Savills as an area with a preserved natural environment, presence of coastal wildlife, and typical vegetation of the northwest region of Scotland.
The real estate agency mentions seabirds, wild geese, otters, and varied vegetation, including willows, rowans, birches, heather, ferns, lichens, and wildflowers present on the land.
In the nearby waters, the commercial material mentions fishing resources and species such as lobster, crab, mackerel, bass, scallops, and langoustine, without detailing conditions for exploitation or commercial use.
As it is an insular property, any use of the location depends on environmental regulations, legal conditions, buyer responsibilities, and specific checks before the sale is completed.
The boat used by the owners does not appear as a mandatory part of the main sale in the confirmed information from Savills, although access by boat is one of the planned ways to reach the island.
The possibility of separate negotiation was mentioned in the initial version of the news, but the publicly available confirmation only points to access by boat or helicopter, with existing landing and mooring facilities.
The acquisition of an island like Mullagrach involves expenses and responsibilities beyond the initial bid, including regular transportation, cabin maintenance, safety equipment, insurance, supplies, and possible permits.
Adapting to the climate of the Scottish Highlands is also part of the practical conditions of use, especially for buyers who intend to visit the property frequently or stay for extended periods.
The announcement states that the ownership is of the heritable type, the Scottish equivalent to the English freehold, and recommends that interested parties consult the legal sale package before making any decision.
The guidance is relevant because areas, boundaries, and images disclosed in real estate ads are presented as approximate and depend on verification by potential buyers.
