CDL’s Tree House in Singapore just set a new Guinness World Record with the world’s largest vertical garden. The building’s green wall measures 24,638.59 square feet and is expected to save more than $500,000 in energy and water costs annually.

Located in a quiet corner of Singapore’s District 23, Tree House is a 24-storey condo building that boasts the world’s largest vertical garden and features state-of-the-art sustainable technologies and elements such as heat-reducing windows and motion sensors that automatically activate lights.

The vertical garden will reduce the estate’s carbon footprint by filtering pollutants and carbon dioxide out of the air. The green exterior wall will reduce heat absorption, which could result in energy savings of between 15 and 30 per cent.

The developer, City Developments Limited (CDL) won the tender for the site in August 2009 and the project was completed in 2013.
