This area covers the mainly private residential areas of Holland Road, Tanglin, Queenstown and Farrer Road. Pockets of HDB housing estates and neighbourhoods are found in the Commonwealth area located at the bottom-left quadrant.
The Singapore Botanic Gardens is found at the top-right quadrant, extending from Napier Road in the south to Bukit Timah Road / Dunearn Road in the north. See area around the Botanic Gardens Central Core for more information about the Gardens. Further to the east (right) of the gardens is the Tanglin Road area which, together with Orchard Boulevard, marks the start of the Orchard Road shopping belt.
As the area is mostly private housing, it is not surprising that only two mass transit rail stations are seen in this map. Commonwealth MRT Station (EW20) and Buona Vista MRT Station (EW21) of the East-West Line are located at the southwest quadrant where the HDB neighbourhoods are.
