The Shard, Western Europe’s tallest building, took three years to build. The Burj Khalifa, tallest building in the world, took nearly six. 

But a new 57-storey tower in the Chinese city of Changshan, while not quite as tall as these monoliths, was just completed in only 19 days. That breaks down to exactly three floors a day. Which is quite an achievement.  

The tower contains 800 apartments, office space for 4,500 people, 19 large atriums to be used as public squares, and a ramp system in addition elevators, so residents can walk or ride bikes to and from their homes and offices. The building's ventilation system will also pump out pollution-free air.

It's the work of construction firm Broad Sustainable Building. The company, which specialises in eco-friendly, pre-fabricated builds, managed the amazing speed of construction by pre-building blocks in factories, then stacking and screwing them together on site – a bit like giant Lego blocks. 

Broad Sustainable Building is presumably hoping this achievement will raise their profile: it's currently angling to build Sky City,  the world's tallest skyscraper, using similar techniques, but progress has been delayed by spiraling costs.

If it goes ahead, the company claims it could spit out the 200-storey skyscraper in just 90 days. 

This timelapse video shows the insane rate of construction, along with an hour-by-hour timer: 

And if that doesn't impress you, here's an unpromising image of what those blocks look like before construction begins.

More than 830 cities have brought essential services back under public control. Others should follow

The wave of cities worldwide rejecting privatization is far bigger and more successful than anyone thought, according to a new report from the Transnational Institute, Reclaiming Public Services: How cities and citizens are turning back privatisation. Some 835 cities in 45 countries have brought essential services like water, energy and health care back under public control.

The persistent myth that public services are by nature more expensive and less efficient is losing its momentum. Citizens and users do not necessarily have to resign to paying increasingly higher tariffs for lower standard services. The decline of working conditions in public services is not an inevitability.

And the ever larger role private companies have played in public service delivery may at last be waning. The remunicipalisation movement – cities or local authorities reclaiming privatised services or developing new options – demonstrates that cities and citizens are working to protect and reinvent essential services.

The failure of austerity and privatisation to deliver promised improvements and investments is part of the reason this movement has advanced. But the real driver has been a desire to meet goals such as addressing climate change or increasing democratic participation in service provision. Lower costs and tariffs, improved conditions for workers and better service quality are frequently reported following remunicipalisation.  Meanwhile transparency and accountability have also improved.

Where remunicipalisation succeeds, it also tends to inspire other local authorities to make similar moves. Examples are plentiful. Municipalities have joined forces to push for renewable, climate-friendly energy initiatives in countries like Germany. Public water operators in France and Catalonia are sharing resources and expertise, and working together to overcome the challenges they meet.

Outside Europe, experiments in public services are gaining ground too. Delhi set up 1,000 Mohalla (community) clinics across the city in 2015 as a first step to delivering affordable primary health care. Some 110 clinics were working in some of the poorest areas of Delhi as of February 2017. The Delhi government claims that more than 2.6m of its poorest residents have received free quality health care since the clinics were set up.


Local authorities and the public are benefiting from savings too. When the Nottingham City Council found out that many low-income families in the city were struggling to pay their energy bills, they set up a new supply company. The company, Robin Hood Energy, which offers the lowest prices in the UK, has the motto: “No private shareholders. No director bonuses. Just clear transparent pricing.”

Robin Hood Energy has also formed partnerships with other major cities. In 2016, the city of Leeds set up the White Rose Energy municipal company to promote simple no-profit tariffs throughout the Yorkshire and Humberside regions. In 2017, the cities of Bradford and Doncaster agreed to join the White Rose/Robin Hood partnership.

Meanwhile, campaigners with Switched on London are pushing their city to set up a not-for-profit energy company with genuine citizen participation. The motivations in these diverse cities are similar: young municipal companies can simultaneously beat energy poverty and play a key role in achieving a just and renewable energy transition.

Remunicipalised public services often involve new forms of participation for workers and citizens. Remunicipalisation is often a first step towards creating the public services of the future: sustainable and grounded in the local economy. Inspiration can be found in the European towns and villages aiming for 'zero waste' with their remunicipalised waste service, or providing 100 per cent locally-sourced organic food in their remunicipalised school restaurants.

Public services are not good simply because they are not private. Public services must also continuously renew themselves, grow, innovate and recommit to the public they serve.

The push for remunicipalisation in Catalonia, for example, has come from a movement of citizen platforms. For them, a return to public management is not just an end in itself, but a first step towards the democratic management of public services based on ongoing civil participation.

Evidence is building that people are able to reclaim public services and usher in a new generation of public ownership. The momentum is building, as diverse movements and actors join forces to bring positive change in communities around the world.
