I am buying a small plot of land (about 0.07 acre). It has a great outlook over the coast. Can I put a shipping container residential building onto it, and what is the maximum size under PD? It would be part of my new company to show the benefits of using renewables such as MVHR, solar PV and thermal, possibly ASHP. With the aim of putting in renewables, would a council be a little more forgiving???
