Time Out says
Rumour has it that 1 Utama has been keeping a huge secret from their shoppers and even their staff. After five years, they have finally unveiled the big secret: The Secret Garden. The rooftop garden encompasses an expansive area of 30,000 square feet filled with over 500 species of carefully curated tropical and temperate plants. No, this is not the rainforest enclave that most people are familiar with in the building, but a new initiative to promote environmental awareness and reduce the carbon footprint. This 'Garden in the Sky' is currently Southeast Asia's largest rooftop garden. There are guided tours every first weekend of the month and you can even use this venue for wedding photography. Check out their website and Facebook page for time and dates of the guided tours.
