The stunning mansion on the Eilean Aigas estate. See SWNS story SWMANSION: A reclusive billionaire has slashed the price of his home in the Scottish Highlands by £12million, it was revealed yesterday (Mon). Canadian telecoms tycoon Brendan Clouston put his stunning mansion and 546-acre Eilean Aigas island estate in Inverness-shire on the market in 2012 with an asking price of £15million. It came a year after he tried to block the forced sale of part of his land to make way for a controversial power scheme. But after almost three years on the market, the property on the River Beauly is now scheduled to go to auction in September for a price in excess of £3million if it has not sold.
