Last week I had the opportunity for a break from work and a trip to Singapore. It has a population similar to that of New Zealand but with the land size equivalent to that of Lake Taupo.

With such a densely populated city, gardens and green spaces must be intentional and well planned; this they have done exceptionally well.

There are some incredible sights of "Green roofs" and "Green walls" of impressive proportions throughout the city. Even the Changi Airport in Singapore has very impressive gardens.

The famous "Gardens by the Bay" with its "Super Trees" opened five years ago.
