OPAL helps community-led housing groups vision, plan and build sustainable and affordable homes

What we do

OPAL works with community-led housing groups during four stages of activity
Go to Vision


What do you want your housing scheme to achieve? Using the One Planet Living framework, we help you shape an ambitious but achievable vision for your project and equip you with the skills and tools you need to get it off the ground.

Go to Plan


We help you prepare a development brief for your project and identify sites for your community. We help you to prioritise your decision-making, support you to work with professionals and guide you through the planning process.

Go to Build


We support you as your homes are being built to ensure that the objectives of your project are delivered during the construction phase.

Go to Live


We help you to develop management and governance systems, so you can live together as a successful community-led housing group.
