The importance of infrastructure in stimulating economic growth in a city and attracting inward investment is well understood by city planners. Transport is generally seen as a key area to address. But what is less well recognised is the importance of housing as part of your infrastructure and the role that housing can play in helping your city retain talent.
Grant Thornton UK highlighted the role that housing plays in a city's future when it interviewed thousands of Londoners about their relationship with the city. It commissioned the research to inform Vibrant Capital, a new conversation bringing together academics, business leaders, creatives and policymakers to discuss how London can sustain its position as a capital of enterprise and Europe's best performing city.
Affordable housing can help cities retain young professionals
The research showed that although Londoners love the city's energy, creative buzz and diversity, many plan to leave the city in the future. Worryingly for London, 32% of these would-be leavers are young professionals aged 25 to 34 – the very people the city needs to retain.
When would-be leavers were asked why they wanted to move away from the capital, almost half said housing affordability was the biggest factor influencing their decision. This finding did not come as a particular surprise. The shortage of affordable housing in London is well-known and now being actively addressed – the city's Mayor has set a target of building 66,000 new homes a year.
But Grant Thornton UK was curious to know how many of these planned new homes were actually being built. So, when we discovered that there were no figures on this, we decided to do the analysis ourselves.
"What our analysis showed is that there's a big gap between the number of planning applications being approved and the number of properties subsequently being built within three years," says Will McWilliams, partner and practice leader in Grant Thornton UK's Government & Infrastructure Advisory team.
"In 2015, for example, London's planning authorities approved applications to build 55,000 new properties. But three years later, only 25,000 of these homes had been built – a 46% attrition rate across the city.”
"We then went a step further and looked at the impact of a new London railway on this attrition rate. And that's where the figures get really interesting."
New London railway and the massive boost to housing
The so-called 'Elizabeth line' is a new 118 km railway that runs across London from west to east. Grant Thornton UK looked at the housebuilding attrition rate within 1 km of the new railway's 41 stations and found that it was almost zero.
"I don't think I've ever seen quite such stunning proof of the power of transport infrastructure to act as a catalyst and attract investment to other areas of infrastructure," says Will.
"The impact on London will be significant. Talent that might otherwise have left the city is now more likely to stay. This will help the capital retain the bright young minds it needs to ensure its continued success as a global city."
Benefits of joined-up infrastructure investment: a global perspective
London is not the only city to experience the knock-on benefits of investment in transport infrastructure. In Qatar, as part of the national 2030 vision, the Qatar authorities embarked on a major road and rail infrastructure programme. A key element of the programme was the construction of a new three-line metro, alleviating congestion in the long term and also supporting Qatar's bid to hold the World Cup in 2022. Grant Thornton advised Qatar Railway Company on this development and this included work on the commercial development opportunities in and around the major stations.
Grant Thornton is also currently working with state authorities in the US and India to improve the impact of investment in infrastructure. In India, for example, we are working with the Government on the 'smart cities' programme, where the ambition is to enable 100 cities to develop 'smart cities' projects. We are currently helping seven cities to develop, co-ordinate and implement their investment plans. Typical investment programmes are in the order of $300-500m. This funding is then matched at the state level and deployed on a range of projects across technology, information and data to improve city infrastructure and services.
"The debate has moved on from 'Should we invest in city infrastructure?'. Today this is a given. Now the conversation is about how you join up investment across housing, technology and transport to enable safe, vibrant, and growing places to live," says Will.
Maximise the potential of your city
Meanwhile, back in the UK, further major improvements to London's transport infrastructure are planned. The Crossrail 2 project will liberate significant areas of land for housing development. So, as you would expect, Grant Thornton UK and others who are keen to ensure that the high cost of housing does not price young professionals out of London, are in talks with the city's transport authorities to ensure that the opportunity is maximised.
Davide Savian, Partner and Head of Real Estate & Construction, states: “In a hyper-connected and increasingly fast-growing world, infrastructures are often thought as the ‘networks’ where ‘big data’ - that are becoming more and more valuable in any field of our society - are exchanged.
However, digital infrastructures are not the only infrastructures that citizens and businesses need. Transport networks are essential to ensure the city life and the development of business operators’ activity. Whether it is urban or extra-urban transport, transport of passengers or freight, or whether it is road, rail, sea or air transport, the possibility to count on modern, efficient, reliable and safe infrastructures represents a primary driver to support the industrial and economic growth of our society.
For a city – but also for a country as a whole – this can represent an essential factor to attract (or retain) talents, especially those between 25 and 34 years old, who can help support the city life and growth, but who could be otherwise stimulated or forced to leave in pursuit of a more suitable place for their professional and human growth.
The presence of adequate infrastructures that can ensure a good mobility and commuting, therefore, it is more a necessity rather than an added value as concerns sustainable work purposes, and housing, i.e. the availability of houses at affordable prices, is as much important in order to retain and incentivize young talents.
Certain of these needs, Grant Thornton professionals all over the world can support the entrepreneurial initiatives, either public or private, aimed at realising the infrastructures needed to improve the life of citizens, the growth potential of businesses and the well-being of the city and the entire society.
