Blow designed various properties for Hugh "Bendor" Grosvenor, 2nd Duke of Westminster, including Château de Woolsack, a hunting lodge in Mimizan, France, near Bordeaux.
The hunting lodge Château de Woolsack was built in 1911 for the British Duke of Westminster (the architect was Detmar Blow).
The existence of bales in ancient times is attested by the custom of the English Lord Chancellor to sit on the so-called Woolsack from which he presides over the House of Lords.
The importance of wool to the English economy can be shown by the fact that since the 14th Century, the presiding officer of the House of Lords has sat on the "Woolsack", a chair stuffed with wool.
