Your application to participate in the Phase Sustainability initiative

We are pleased that you wish to support our Phase Sustainability initiative. Please note that submission of the application is in itself not a guarantee that participation will be approved. The initiative is addressed explicitly to architects and planners who are involved from the outset with the builders in the planning process and address the sustainability goals set out in the Declaration of Sustainability and are able to transpose them where possible into planning agreements. We would ask you to fill in the motivation field in order to facilitate our review of your application.
