Theodorus Wijdeveld designed and supervised the creation of both the villa and the original garden between 1909 and 1911. The rare monumental external facade of the Villa Endymion has been designed by the architect in a combination of "Um 1800" and Sezession stylesand evokes a natural and seamless flow through the grounds. Almost 15 years after the completion of this masterpiece Wijdeveld was again retained to design the pergola and the garage with separate living quarters for the chauffeur. Above the main entrance of the house hangs a copper plate with the inscription:
"Endymion - A thing of beauty is a joy for ever."
This quote is taken from the celebrated piece of poetry by John Keats (1818) entitled ‘Endymion’ after which the house is named.
