Hi.
It could have been from the Admiralty yacht of that name, completed 1903 (2514 tons), broken up 1935:

If it is this yacht, then I would guess that quite a number of famous people may have walked through that door, including Churchill. From "Churchill and Chartwell", by Stefan Buczacki (2008), pp.47, 48:
"The HMS Enchantress that took Churchill to sea was one of a lost
breed of ocean-going splendours, a steam yacht. They were glorious
craft with slim and elegantly raked funnels, a bowsprit and sumptuous
polished wood and brass, epitomising late Victorian and Edwardian
style and grace. In 1911, the navy had two - the twin-funnelled Royal
Yacht
Victoria and Albert III and the single funnelled
Enchantress with a
complement of 196 officers and ratings which was the the disposal of the
Commissioners of the Admiralty, and especially of the First Lord. And
no First Lord took greater advantage of her than Churchill. He had
been in post for only a few weeks before he was on board; and between
his appointment as First Lord in late 1911 and the outbreak of war, he
was on Enchantress for a total of eight months; indeed during some
months, such as November 1911, he was seldom away from her. Much
of this time he was visiting ships, dockyards and other naval installa-
tions, although the First Lord was a generous host and Clementine and
other family members and friends were often invited to share the pleas-
ures of life afloat.
In 1914, Enchantress served as a field hospital for officers but was
then laid up until recommissioned in January 1919. She was ultimately
broken up early in 1935 when Churchill was asked if he would like to
have the pane of glass from the ship that had been engraved with his
coat of arms. He declined, saying he had nowhere to hang it."
However, on the completion of the new sloop of the same name in 1935, The Times (08 Apr 1935) reported that:
"All the furniture and plate from the old
Enchantress is being transferred to the new vessel,
and by using this equipment the official apart-
ments of the new Enchantress will be fitted out
at little cost."
According to
Naval-History.net, this new Enchantress served through WW2, was sold after the war and renamed Lady Enchantress, and was broken up in 1952 at Dunston on the Tyne.
So perhaps your door was part of this history. Or was another Enchantress altogether (there were several yachts with the name)
I don't think it was the one sold in 1905 though. Despite the note on the Miramar entry about being broken up, it seems to have been taken over by the Royal Motor Yacht Club in that year and fitted out as a floating clubhouse. It remained with the club up until the start of the war, attending numerous regattas and hosting club dinners. An article in The Times (20 Oct 1919) possibly reports of her demise by fire in 1915:
"The last loss of that year [1915] was Resource II, 1,000 tons, which
was destroyed by fire in Southampton Harbour,
where she was used as a headquarters for the Royal
Naval Volunteer Motor-Boat Reserve. The vessel
was better known as Enchantress."
