Research challenges NIMBY concern about new homes

Having new homes built next door to you may not damage the value of your own home after all. The popular NIMBY concern has been challenged in new research commissioned by Barratt and the NHBC Foundation and written by the London School of Economics (LSE).

The report, Understanding the local impact of new residential development, addressed the question of whether a new development will always reduce prices or reduce the rate of increase in prices in the immediately surrounding area. Examining the impacts of eight recent residential Barratt developments on their local areas, the research concluded that prices did not decline as a result of development, although sometimes there may be some limited impact during construction. Once the developments were completed, the local areas generally moved with the market.

The selected sites all involved fewer than 300 units and were substantially completed within the last five years. Spread across the South and Midlands these sites are typical of housing development outside city centres or wholly rural areas. The aim was to exemplify ‘ordinary’ developments mainly on sites where there had been objections – some significant – at planning permission stage prior to development. Five sites were built on land with previously higher amenity value, and three were built on land that previously had lower amenity value including derelict industrial land.

The research found:

  • House price changes in the surrounding streets and the broader three/four-digit postcode districts suggest that new developments may stabilise or even increase prices in the immediate areas once development is complete where the market is generally stable and rising. They also suggest that there is almost no evidence of longer-term negative impacts
  • For sites where a high level of opposition was experienced throughout the planning and construction processes, this opposition tended to decrease once the development is completed. In one case where there were high levels of opposition, at least half of all eventual purchasers of the new homes previously lived within 5 miles of the development.

Neil Smith, head of research and innovation at NHBC said: “It is understandable that homeowners will be anxious to protect their investment in their homes, and concerns about the negative effects of new developments have compounded the issue. While there are clearly a number of factors affecting property values in specific areas, this research challenges the assumption that new build developments will adversely affect local house prices.”

Philip Barnes, group land and planning director at Barratt Developments said: “Whilst this is a small sample it is reassuring that new housing developments appear to have little discernible impact on local house price patterns, indeed in some areas can boost local market confidence.”
