Both can prepare and manage a planning application. For single homes, dual occupancies and smaller developments of up to about eight dwellings, the Building Designer who designed the project is usually the better choice. They know every design decision, the design has been prepared to respond to the planning policy, and they can negotiate with the council planner or redesign quickly when changes are needed.
For larger and more complex developments, typically ten or more dwellings, an experienced town planner is better placed to lead the application. On these projects we work alongside a town planner, who prepares the planning report and leads the negotiations, while we look after the design and drawings.
