Menteng Project was the first housing project in Jakarta that follows the first law of urban planning in Batavia, known as "Bataviasche Bouwverordening". Menteng was influential in the introduction of a new Indies architectural language. New Indies Style, a modern architectural movement in the Dutch Indies, was strongly implemented in Menteng. The new style combines the old Indisch style one-storey villas with modern two-storey structures. Prominent roof form (e.g. mansard roof and pyramid-shaped hip roof) was characteristic of house design in Menteng. Other characteristic element of houses in Menteng were front terraces, wide courtyard, characteristic textures in the wall, tall windows and doors with cross ventilations. Other architectural style popular in Menteng during its development were mostly early 20th-century modern movement e.g. Art Deco, Dutch Nieuwe Zakelijkheid, the original New Indies Stlye, and Art Nouveau. Older style e.g. Classicist Empire Style and Old Indies Style sometimes appear in the architecture of old villas at the fringe of Menteng Project, some are converted into museums, otherwise demolished for new development.
