Description

The Hill Garden southern summerhouse is a summerhouse located south-west of Inverforth House, serving as the central feature of the Southern Pergola. It was built between 1906 and 1910 by Thomas H Mawson as part of a garden design for Lord Leverhulme at The Hill, which is now known as Inverforth House. This section of the garden is now owned separately from the house. The summerhouse has an octagonal plan and features paired concrete Doric columns that support a wooden entablature and an open superstructure. There is a brick screen wall on the west side. It can be accessed from the north and south sides via the Southern Pergola and from the east side by steps leading from the garden. Historically, the terraces were constructed using spoil from the excavation of the Hampstead Tube. The summerhouse offers excellent views over Hampstead Heath and back towards the house. The garden was divided when the house was converted into a hospital, and this part of the garden is now open to the public.
