An interesting challenge for students would be to give them the task of creating an idea or proposal on what they would build on a greenfield site. Students should present a proposal for a development on an identified greenfield site near school. Points for consideration would include - planning issues, target buyers and finally how the development will benefit the local economy and environment.
