Event summary

The first in a series of online events, held in conjunction with our Build Net Zero NOW campaign. During this session, we will explore the role of modern methods of construction in delivering high quality, net zero new homes.

About the campaign

The campaign was formally launched at a Good Homes 2020 conference session on 3rd November 2020 and will run throughout 2021. The aim is to showcase how new homes can be built at scale to net zero standards now, rather than by 2025 or 2030. This ambition is shared by many GHA members, including members of our local authority Vanguard Network and housing association Pathfinder Network, that are set to build 100,000+ new homes over the next 10 years.
