Villa Isola (now Bumi Siliwangi) is an art-deco building in the northern part of Bandung
, the capital of West Java province of Indonesia
. Overlooking the valley with the view of the city, Villa Isola was completed in 1933 by the Dutch architect Wolff Schoemaker for the Dutch media tycoon Dominique Willem Berretty, the founder of the Aneta press-agency in the Dutch East Indies. The original purpose of the building was for Berretty's private house, but then it was transformed into a hotel after his death and now it serves as the headmastership office of the University of Education Indonesia.
The design of the Villa Isola by the architect Wolff Schoemaker, was influenced by indigenous Javanese philosophy. The orientation of the building is according to the north—south axis, where the building faces Mount Tangkuban Perahu
to the north and the city of Bandung to the south.Schoemaker was a firm follower of the art-deco style, which he mixed with local ornaments. Many circular shapes decorated the whole complex, the design of which reminds people of the shape of Candi in the east of Java. Circle is the main theme of the complex, both inside and outside the villa, including the gardens.
The main entrance is located at the center of the north facade shaded by a concrete canopy arch supported only by one pillar. The interior of the first floor consists of a lobby with a twisted staircase to the second floor, and a family room. A large window in a half-circled curve shape decorates the family room completed with an open balcony with a parapet of steel bars, with a panoramic view of the city. The family room is also equipped with a circular shape of toilet.
Two gardens at different levels surrounded the complex. The higher north garden, was a European style garden with a rectangular pond and a statue in the middle. Orchard flowers dominated the garden and five black swans were specially imported to garnish the pond. A road divided the garden symmetrically to allow cars pass through from and to the garage. A half-circled staircase attached to the main building enhanced the symmetrical design of the garden.
The large south garden occupied most of the complex. Circular ornaments filled the south garden, starting from the building by another half-circled staircase. There are also similar staircases on the west and the east sides of the building. The garden was divided into circular areas whereas the building was positioned at the center of these circles, creating the impression that the building was an integral part of the garden.
