Bukit Batok Driving Centre, one of Singapore's oldest driving test centres, is a peculiar sight from above. Little cars make loops and turns, manoeuvring through an obstacle course which is harder than it looks. The facility has three years left on its lease and the Urban Redevelopment Authority has said that it will have to make way for housing within the next 15 to 20 years.

With Singapore's vibrant economy paving the way for some of the most innovative architecture in the world – take the durian-shaped Esplanade theatres for instance – amazing geometries are hidden in many places.

The Bishan Bus Interchange was built in 1989 to support the development of Bishan as a new town. A covered interchange concourse surrounds the open-air bus park.

Designed by Chartered Design International, the Bishan Home for the Intellectually Disabled looks like a brain. From an initial population of slightly over 20 residents, the home is now near full capacity with more than 130 residents.

The wave pool at Jurong East Swimming Complex looks like a giant nose from above, while the Bishan Home for the Intellectually Disabled looks like a human brain.

The Hard Rock Hotel is one of four hotels at Resorts World Sentosa, which opened in 2010. The hotel houses a treasure trove of more than 120 pieces of memorabilia belonging to rock stars including David Bowie and Elton John.

Built in memory of the civilians who lost their lives during the Japanese occupation of Singapore from 1942 to 1945, the Civilian War Memorial sits on serene parkland amid busy city traffic near the Padang and City Hall.

The newly opened Ng Teng Fong Hospital looks like an anatomical model of the human circulatory and digestive system. It is not known, however, if the layouts of these places were designed with such shapes in mind.

Resembling a mosquito coil, Bishan Harmony Park's hedge maze was constructed in 2009. It is located at the junction of Bishan Road and Braddell Road.

The Omni-Theatre, established in 1987, is Singapore’s only IMAX dome theatre. It is equipped with state-of-the-art IMAX technology, and is home to the world’s latest and brightest 8K digital planetarium system.

MacRitchie Reservoir is Singapore’s oldest reservoir. It was completed in 1868 and renamed in 1922 after Mr James MacRitchie, the municipal engineer who supervised its extension in 1891. A Phantom 4 drone from Shenzhen-based tech company DJI costs about $1,700, and comes with an in-built 4K camera that takes crisp images.
