Thematic entertainment design and construction firm Sanderson Group have been named as masterplanners for a US$5bn (€4.47bn, £3.87bn) development in Bali, Indonesia, dubbed a “new wonder” by its founders.

Margarana Dream City – which covers 2.5sq km (0.95sq m) – follows a theme of “innergy”, with a pyramid-like tower at the heart of the development “drawing the positive 'chi' into a green city”. The mixed-use development offers a variety of nature health, wellness and relaxation options.

Included in the expansive plans will be hotels and resorts among a slew of attractions including stone age – an area where visitors can “get rid of crowded modern life”, travelling back to a time where they can explore ancient wisdoms of Indonesia. The Green Haven will also feature an attraction based around horticulture where visitors can learn the secrets to growing their favourite plants. The development will also feature 404,000sq m (100 acres) of movie studios and a “City of Lights” arena.

The project supports plans by Indonesia’s government and Ministry of Tourism to develop the area of northern Bali into a world-class tourism hub.

“I had a dream that I would make something completely original that would amaze the world,” said Grand Master Patriq Chang, co-founder of the development along with Nanang Iskandar.

“Now that dream will be fulfilled, benefiting the world and amazing every human on earth. It is not a dream, it is a message. Margarana Dream City will be the world’s first Innergy City, a place where positive energy grows. It is a new wonder and it is happening here in Bali.”
