Many country houses were built by the Dutch in other colonial settlements, such as Galle, Cape Town and Curaçao, but none as extensively or elaborately as in the Residency of Batavia (an area that includes parts of modern-day Jakarta, West Java and Banten provinces).
Despite its heritage and protected status, many of the Indies' country houses were left to deteriorate or were demolished, often due to lack of maintenance.
In 17th century Netherlands, the increasing importance of Holland as a major maritime nation with a growing commercial empire, particularly in the East, had generated capital for the merchant classes of Amsterdam.
This second residence, or landhuizen, ranged from modest rural retreats to luxurious manor houses, and were typically seated along the rivers Amstel and Vecht.
Unlike their Dutch counterparts, Batavian estates included extensive ancillary quarters to accommodate servants, often in the rear of the house.
Still a two-story structure, the facades are protected from the sun and heavy rain by a large overhanging roof on all sides.
The upper floor is usually reached by an external staircase and often the central portion was left open for maximum ventilation; as well as tall windows with louvered shutters.
The verandah often had potted palms, cool concrete or marble tiles covered with split bamboo mats.
The western reference appears in the neo-classical Tuscan columns supporting the large roof overhang and the decorated doors and windows.
Practical measures carried over from the earlier Indies Style, which responded to the Indonesian climate, included overhanging eaves, larger windows and ventilation in the walls.
