The house was built in 1700 by Charles Keys.
The house was used as a masonic lodge between 1730 and 1745, which may have been why Keys named it Golden Spikes.
It appeared on John Rocque's Map of London, 1746.
Naval captain Fountain North owned the house between c. 1775 to 1811.
He re-named it The Grove and added a quarterdeck to the roof of the house.
He also added a bulwarks and portholes to the property, and in 1805, bought the nearby grove and demolished it to extend the house's garden.
In the late 18th century, the house was mistaken as belonging to Admiral Barton.
The problem arose because a print of The Grove was incorrectly entitled Admiral Barton’s Hampstead.
A possible explanation for the confusion was that Barton, who lived in Hampstead, fired cannonballs from his roof, and so it was assumed they were from the quarterdeck of The Grove.
As a result, the house became known as Admiral's House, even though no admiral has ever lived in the house.
Admiral Walk, the road on which the house is situated, is similarly misnamed.

In the 19th century, John Constable painted Admiral's House a number of times.
One painting, The Grove, or Admiral's House, Hampstead, was bought by Hugo von Tschudi for the Berlin Alte Nationalgalerie, was later on display at the Tate Britain, and is now in the collections of the Victoria and Albert Museum in London.
The painting is believed to be the view of Admiral's House from Constable's nearby house.
Another painting, The Romantic House at Hampstead has been in the collections of the National Gallery.
George Gilbert Scott lived in the house between 1856 and 1865, although he decided that Hampstead was too cold for him.
In 1910, London County Council commissioned a blue plaque for Scott on Admiral's House.

From 1917 to 1926, John and Winifred Fortescue lived at Admiral's House.
During his time in the house, John Fortescue wrote his multi-volume book Fortescue's History of the British Army.
The couple moved from Admiral's House to Windsor Castle.
In 1941, Norman Thomas Janes produced a watercolour painting of Admiral's House that is located in the V&A Museum collections.
Admiral's House is believed to have been an inspiration for P. L. Travers' Mary Poppins books.
Travers' character Admiral Boom likes to fire cannons, as did Admiral Barton, who at the time was believed to have lived at the house.
Scenes from the 1964 Mary Poppins film adaptation were filmed at Admiral's House.

In 1950, the house became a Grade II listed building.
