How to tackle growing urbanisation

By Johan Andersson, May 05 2015

Living on top of the world. Houses on rooftops.According to the 2014 revision of the UN report World Urbanization Prospects, the amount of people living in urban areas will increase from 54 per cent today to 66 per cent by 2050. By 2045 the world’s urban population is  expected to exceed six billion. This will no doubt create new challenges on housing, infrastructure, public transportation, energy and many other areas.

A part of the solution is often to increase vertical density. In other words building higher buildings where more people and businesses can fit in on the same area. That way the cities’ total area don’t have to grow to make room for the people moving in.

New built high-rises and skyscrapers are usually what comes to mind when you think of increased vertical density, but there are ways to get the same effect without demolishing present buildings or occupying public space to build new higher buildings. Why not build on top of what we already have?

The World Urbanization Prospects report points out that “sustainable urbanization is key to successful development”. A growing urbanisation is said to have positive environmental effects due to the fact that it is typically cheaper and more environmentally friendly to provide public services such as electricity, water and sanitation to an urban population compared to a rural population.

By using steel in the construction of buildings you get even more sustainability advantages. Thanks to it's high grade of recyclability and low carbon footprint it's one of the most eco friendly building materials in the world. So, is there a way to combine steel construction, urbanisation and increased vertical density? 

Recently we have been involved in a project creating 12 new apartments on the roof of a shopping center in the Moravian town Luhače in the Czech Republic. Looking at the header image you wouldn’t think it’s actually on top of another building, but it is. All the houses are built with a light weight steel frame and steel roofing and guttering.

This is one way that we can help tackle a part of the challenges of growing urbanisation. There are many challenges within many fields but there are solutions to be found.

The lightweight steel constuction is very favourable when it comes to increasing vertical density.The lightweight steel constuction is very favourable when it comes to increasing vertical density.

Benefits of rooftop lightweight steel construction

  • You can build on spaces not accessible for heavy machinery
  • Increase population without any needs for new expensive land
  • You’ll get a unique and exclusive property
  • Steel is nearly one hundred percent recyclable which means it has a low carbon footprint
