WOULD you like to own a piece of Scottish art history? This former Charles Rennie Mackintosh studio could be yours – if you have a spare £14.95 million, that is.

When the Scottish architect and his wife, fellow artist and collaborator Margaret Macdonald Mackintosh, moved their supplies into Glebe Place in London in 1915, prices were more modest.

The couple rented two adjoining studios behind a red brick cottage in the city’s Chelsea district in 1915. They’d gone to Suffolk a year earlier and left when he was found to have letters from artists based in Austria and Germany, something which triggered suspicions he may be a spy.

The National:

Mackintosh, whose accent was taken for German, was kept in a cell overnight and one Walberswick village dignitary apologised for that in 2013, almost 100 years on.

Now the city haven where they worked for 10 years has gone up for sale.

The two studios have been converted along with another and a red brick cottage to create a single home for a buyer with deep pockets.

Though little remains of the decor the Mackintoshes would have been familiar with, the big-money conversion retains strong links to the pair, with exterior railings in the rose motif familiar to Mackintosh fans worldwide and a blue heritage plaque on the front of the property.

The Mackintoshes spent several years creating here, though they did not live within the cottage but resided nearby instead. However, it is known that Margaret entertained there, and during their London days the couple undertook commissions including those for 78 Derngate, the only Mackintosh-designed house in England, and the Dug Out basement extension to the Willow Tea Room.

Whilst in Chelsea, they were in famous company – composer Ralph Vaughan Williams lived there, as did painter Philip Wilson Steer and poet John Betjeman.

Celebrations were held at 43a Glebe Place in 2009 to commemorate the Mackintosh connection and the studios were still let out to creatives until 2012, when then-owner the Church of England sold it and the cottage to a developer for £1.225m.

Eight years later, the price the next owner will have to pay is far higher.

Set over 3870sqft, the property includes a courtyard, gym, steam room, roof terrace and – perhaps the biggest London luxury of all – parking for two cars, plus three bedrooms, three bathrooms and an open-plan living area.

Listed by The London Broker for a private vendor, it is described as “truly unique” and has been given a multi-million overhaul spanning three years.

The online brochure calls it “an exquisite and self-indulgent” home.

Images reveal exposed roof beams, parquet flooring and a white and black colour scheme that’s not dissimilar to some of the elements at the Mackintoshes’ Hill House, the Helensburgh gem currently undergoing major exterior restoration works.

The couple quit the UK for France in 1923, but were later to return. Mackintosh was diagnosed with cancer and died in London in December 1928. Margaret – who had met her husband while both studied at Glasgow School of Art with her sister Frances and their mutual friend James Herbert McNair, who Frances would marry – continued to work in the city and died five years after her husband in 1933.
