Areas

Blair Plain

The Blair Plain Residential Historic District, located to the west of the Downtown Core, is still an attractive residential area with some commercial activities along Kampong Bahru Road. It is a compact cluster of two-and three-storey shophouses and residential terrace houses of the Early, Transitional, Late Shophouse and Art Deco Styles.

Cairnhill

The Cairnhill Residential Historic District, located to the north-west of the Downtown Core, is a quiet residential area of predominantly two-storey terrace houses built in the Late Shophouse and Art Deco Styles. Today, though the area is surrounded by high-rise buildings of varying scale, the charm of the prewar terrace houses is still retained.

Emerald Hill

The Emerald Hill Residential Historic District located to the north-west of the Downtown Core, is an attractive and quiet residential area. It has some commercial premises in the shopping zone along Orchard Road. The predominantly two-storey terrace houses showcase a variety of architectural styles ranging from Transitional to Art Deco Styles built over ninety years. There are some modern high-rise buildings towards the northern end of Emerald Hill Road.
