Pop-up housing built in Amsterdam

Offsite built housing – can it solve London’s housing crisis?

Start date: 25 October 2016
End date: 16 January 2017

Please note that the submission deadline for this investigation has been extended to 16 Janaury 2017.

Nicky Gavron AM, Deputy Chair of the London Assembly Planning Committee has launched a new investigation.  The review will assess the potential of offsite-produced housing to bridge the gap between London’s housing need and supply.

Nicky is particularly interested in views from the following sectors: offsite housebuilders, contractors and those involved in the supply chain, housing associations, local authorities, PRS specialists, the retirement housing sector and investors.[1] 

 Views from residents living in modular homes are also welcome.

Key Facts

London needs another 49,000-80,000 homes per year to cope with the projected population growth of a million in the next ten years. Yet, London is delivering less than half, and maybe only a quarter, of the new homes is needs annually.

In 2012 the Mayor’s Barriers to Housing Delivery Report suggested that a range of factors were potentially impeding housing completions:

  • There are a number of approved sites owned by firms that do not actually build houses.
  • Developers face challenges in obtaining development finance following the recession.
  • The capacity of the housebuilding industry and the speed and consistency of public sector involvement.

In 2015 the Outer London Commission noted that developers tend to ration the delivery of private sale units in order to maintain sales values and prices. As a result of the failure of ‘traditional’ construction to deliver enough housing, momentum is growing for offsite built modular housing using Modern Methods of Construction.

Our investigation


The review is asking the following key questions:

  1. What is the potential for modular and offsite housing to help solve London's housing crisis?
  2. What are the factors that have prevented, and are still preventing, the adoption of this type of housing more widely?
  3. What role can the Mayor play in removing barriers and accelerating the use of modular housing for London’s new homes?
