Buddhist temples and/or a royal palace. The superstructure of these buildings would have been timber (as suggested by holes found in the foundations). However, these had long since disappeared by the time the foundations were discovered in 1819. Apart from some archaeological fragments, like jewellery, porcelain, coins and an inscribed stone, there few material artefacts from the pre-colonial period, and no buildings or even ruins remaining today. Colonial period The city of Singapore was planned by Sir Stamford Raffles in 1822, and his layout for the city, the Raffles Plan of Singapore, largely survives to this day, even if the city has expanded greatly through the years. Raffles specified the area for government offices, various ethnic communities, religious buildings, commerce and education, as well as a Botanic Garden. Raffles planned the city down to the size of the house, the widths of the streets, and the material to be used. Raffles' regulations for the city also has some influence over the architecture, and some of their effects may still be seen in the shop houses; for example it is stipulated that they should not be over 3 stories high, and needed to have an obligatory five foot way. Raffles himself opted for a Malay style house made of wood and atap (Raffles House on Bukit Larangan or Fort Canning Hill, once called Government Hill), other Europeans of the period however preferred European style buildings of brick and stucco. Singapore's most prominent architect in the early colonial era was George Drumgoole Coleman, who was responsible for many of these early European style buildings, few of which survived. Those that did include the old Parliament house and Caldwell House at CHIJMES. In the 19th century, two hybrid building typologies evolved in Singapore. While their origins can be traced elsewhere, these building types underwent significant local adaptation and modification before spreading regionally. As a result, they are Singapore's earliest known architectural innovations and exports. These hybrid building typologies were the shophouse and the black and white bungalow. Shophouse The old style shophouses are shops with one or more stories of living accommodation above it. These shophouses typically have a so-called five foot way which is a covered walkway located in front of the shop doors, with the upper floors shielding the pedestrians from the elements. This is a result of the Raffles Town Plan (1822) for Singapore with the stipulation that "all houses
