About the Capitaspring Building & Gardens

The Capitaspring building was completed in early 2022. At 280m high, it shares the ‘2nd highest’ building ranking along with 3 other buildings, all the same height. This is due to Singapore having a cap of 280m on any new building. It's owned by Capitaland, a major property developer in Singapore and the region. Designed by BIG-Bjarke Ingels Group, and Carlo Ratti, it is very much a flagship building for the company and Singapore in general, with the relatively unique use of planting throughout the building. Current tenants are the big investment house JPMorgan, for example. 

An article about the building

Within the tower are three restaurants. These are:

‘Sol and Luna’ on level 17 - a casual latin inspired theme

‘Kaarla’ on level 51 - Fine dining coastal Australian

‘Oumi’ on level 51 - Fine dining Japanese

Originally there was no concept of a ‘food forest’ or similar from the architects, and indeed, the chef's garden only takes up 50% of the overall rooftop space, with the other 50% planted in typical ornamental, low maintenance fashion. Rather, the addition of the edible section came from 1 Group, who reached out to a local company, Edible Garden City Pte Ltd to help with the design and installation.

Edible Garden City was started in 2012 with the aim of ‘helping Singaporeans grow their own food’. It has 3 pillars to the business, one being food production at 2 ‘urban farms’, which supplies produce to many restaurants through the city, including many Michelin starred. The second pillar is education, which runs workshops for the public at the aforementioned urban farm, along with onsite workshops for teachers in schools across the city. Thirdly, they design and build edible gardens, with over 260 built to date. The majority of these are gardens built within schools so that the students have access to a working garden, however many gardens have been built for commercial/hospitality venues, including the famous ParkRoyal Hotel, Marina Bay Sands etc. The remaining founder Bjorn Low, is a very recognised figure within Singapore for his environmental efforts.

The garden was opened in Feb/march 2022 and so is still quite new and produces approx 70 - 80 kgs of produce a month. For example, here is a breakdown for October:

Apple mint 200gm

Brazilian Spinach 19.6kg

Fame Flower 1kg

Lemon Balm 800gm

Lemon Myrtle 1.5kg

Moringa leaves 10gm

Kaarla Salad mix 12kg
