Kate Lamb, Jakarta – It's Thursday and the residents of Jakarta's Cosmo Park are out jogging, watering their plants or walking their dogs along neat asphalt roads.
Neighbourhood kids pedal their bikes under frangipani trees and peach-coloured bougainvillea to the pool and tennis court. Apartments, comfortable and modern, sit side by side, with barbecues and toys stacked outside.
Quiet and orderly, it feels like any other suburban idyll – but there is one difference. Cosmo Park is a village in the sky, perched 10 storeys up on top of a shopping centre and car park, a world away from the heaving megalopolis below.
It is a surreal urban bubble, where normal life unfolds at an abnormal altitude. To access ground level, resident drive their cars down a ramp. A tall metal fence runs around the perimeter to make sure no one falls or drives off. Peer beyond the fence and you can spot the city's landmarks below.
Cosmo Park was built 10 years ago but was largely unknown outside Jakarta until last month, when a drone photograph broadcast its oddness to the world.
In June, Twitter user @shahrirbahar1 posted a bird's eye view of the complex, 78 two-storey, cookie-cutter units on top of the parking lot with Jakarta's immense urban sprawl in the background. It was a photo that captured both the scale and incongruity of the project.
"Good morning Jakarta," he wrote. "What type of person thinks about developing a housing complex on top of a building?"
Retweeted almost 27,000 times, the post spawned a long thread of incredulity and wisecracks (how do food delivery drivers find it?) but also serious questions about the wisdom of the city's urban development, such as how might a complex like this fare in an earthquake?
Home to 10 million people and almost three times that including the greater Jakarta area, the Indonesian capital is buckling under the weight of its problems, from chronic floods and unbelieveably bad traffic to severe pollution, overcrowding and the fact that it is literally sinking.
So severe are the city's problems the president has once again raised the idea of moving the capital.
Is Cosmo Park some kind of postmodern dystopia or, in a city beset by perennial woe, an ingenious use of urban space? While some outsiders are unconvinced, those who live at Cosmo Park offer glowing reviews.
"It's a lovely oasis," says Fazila Kapasi, as she tails her four-year-old son around on his bike along one of the complex's neat roads. "I cannot recommend it enough."
Fazila and her husband moved to Jakarta from Mumbai, and chose Cosmo Park partly because they were concerned about Jakarta's floods. But after living there for six years Fazila can reel off a string of other advantages, including that it is less isolating than standard apartment living.
In the afternoon Fazila stops to chat to her neighbours, while most days she and her son feed the pigeons that live in a nearby tree. She also has her own garden, where she has a hammock and space to grow aubergines, tomatoes and chillies.
"It is so good. There is so much open space, my son can ride his bike around. It's so central, it's really safe, and there is a lovely neighbourhood feel," she says.
At Cosmo Park there is an uncanny sensation of being simultaneously up and down, but residents are used to it.
"I feel like this is a real house, not an apartment," exclaims Indri Lestari, who moved into Cosmo Park with her husband, who is Spanish, and their young son three months ago. "It's just there is no kaki lima [street food cart] here," she jokes.
Indri says she laughed when she saw the complex on Instagram. "It's high here, for sure," says Indri, who moved from a higher apartment block nearby. "But lots of places are and here we have more space and privacy, and it's better for my family. My son can play outside, just out the door."
Situated amid a cluster of mega malls in Jakarta's centre, Cosmo Park is one of two such developments in Jakarta by the Indonesian property developer the Agung Podomoro Group, and was built according to regulations. The second is above the Mall of Indonesia in the city's north.
"But this one is more popular," notes the real estate agent who showed the Guardian around Cosmo Park, past the pool and launderette and minimarket, as she extolled its convenient location.
"A lot of foreigners choose this place," she said, before leaving with a parting note: "You know who to call if you want to live here."
