Tall residential complexes often share very little common space, leading to a relatively solitary living experience despite the density of dwellings – this design aims to change that paradigm dramatically.

Indeed, helping people get to know their neighbors the driving concept behind this building in Antwerp, Belgium, where similar units are clustered around shared balconies and gardens.

Communal dining, rooftop deck, bike repair and indoor green spaces also encourage further interaction, increasing opportunities for chance encounters. As Black Swan author Nassim Nicholas Taleb writes, “This makes living in big cities invaluable because you increase the odds of serendipitous encounters — you gain exposure to the envelope of serendipity”

Designed by C.F. Møller Architects and Brut Architecture and Urban Design, the idea is to increase interactions both within smaller sets of apartments and throughout the complex.

All of this is meant to help residents form bonds more quickly, beyond the one-off greetings in elevators and periodic meetings in one-per-building community rooms.

The conceptual intent is also cleverly legible on the exterior of the building, with a facade that is broken down into different sections to create a series of scales showing small individual units and collections thereof within the framework of the larger structure.

With over $200 million from more than 3,500 supporters, the world’s largest crowdfunding campaign has generated the means to create the highest skyscraper in Colombia (and the first new one in 40 years).

The communal nature of the stake puts both the property and power in the hands of the contributors, who in turn receive stake in the finished structure being built in downtown Bogotá. This approach, facilitated by the Prodigy Network, also distributes the risk of this bold venture between those with the motivation to see it made a reality – primarily locals and others with a vested interest in the city’s future.

The structure will address a lack of dense vertical growth in a city that has suffered from sprawl, on the one hand, and too-busy streets on the other. It aims to create a residential, commercial and institutional focal point in a location “where tourism, culture, education and shopping are all together, but also where traffic and congestion demand different means of development.”

Green strategies include advanced water collection systems with graywater reuse, green roof elements, advanced natural lighting optimization and supplemental passive heating and cooling systems.

More statistics on the finished project: “When complete the BD Bacatá will be 66-stories high and 1.2 million square feet. Development will include office and retail space, apartments and a hotel. The 364-room hotel, located in the tallest tower of the complex will be operated by Eurostars, and feature such amenities as a business center, restaurant, cafeteria, and full-service gym providing hotel guests with above-and-beyond service to ensure their experience will be worth remembering.”
