Planning committee wants new rules for a 鈥楧esign for Manufacture and Assembly鈥 approach to London housing

The Mayor of London should set up a kitemark scheme for offsite manufactured housing, according to a report by the planning committee of the Greater London Assembly (GLA).

The 鈥楳anufactured Housing Design Code鈥 should be 鈥渄eveloped in conjunction with designers, manufacturers and housing providers and specify the key rules for a 鈥楧esign for Manufacture and Assembly鈥 approach to London housing鈥, the committee recommended.

The term 鈥楧esign for Manufacture and Assembly鈥 is used by Laing O鈥橰ourke, which contributed to the report, to describe its factory-based construction methods. Other contributors included housebuilders Barratt and Berkeley, architect Rogers Stirk Harbour + Partners and consultant Arcadis, 

The GLA report, entitled Designed, Sealed, Delivered, said the code 鈥渟hould be branded as a Mayoral 鈥榢ite mark鈥 supported by suitable warranty providers鈥 and 鈥渨ould drive a more standardised demand profile which can be delivered by a range of technologies and systems鈥.

The five-strong GLA planning committee, chaired by Labour鈥檚 Nicky Gavron, made five other recommendations to the Mayor in its offsite report:

  • Set up a framework for offsite manufacturing specialists, to attract 鈥渁 sufficient number of developers and contractors capable of delivering housing using offsite-led solutions which are suitable for the variety of sites and specific challenges that exist in London鈥.
  • Look at the potential of using GLA and especially Transport for London (TfL)-owned land to stimulate the offsite sector.
  • Announce a further round of the Mayor鈥檚 Innovation Fund specifically focussed on offsite.
  • Provide a 鈥渃lear and strong leadership role鈥 in the development of awareness of offsite鈥檚 potential.
  • Look for ways to encourage the use of offsite to achieve wider strategic objectives and examine if there are any policy barriers to wider adoption.

Gavron said: 鈥淭oday鈥檚 offsite manufactured homes are characterised by their high quality, precision engineering, digital design and eco-efficient performance, truly twenty-first century homes. It is clear with strong political leadership, the offsite sector is poised to achieve a step-change in delivery, but it needs coordinated continuity of demand, along with land, policy and funding. The Mayor is ideally placed to respond to this call to action.鈥

And Mark Farmer, chief executive of Cast Consultancy and author of last year鈥檚 Farmer Review, said: 鈥淣ow is the time to show strong political leadership to establish a mainstream precision manufactured housing market in the capital. There is also a great opportunity for the Mayor to align this into his separate 鈥楽kills for Londoners鈥 manifesto commitment and the Construction Academy Scheme initiative.鈥

There has recently been a surge in offsite manufacturing housing schemes in the capital, and plans have gone in this month for the world鈥檚 tallest modular building in Croydon. This will be 44 storeys with a planning consultation due to start in October.
