We're looking to build a two storey extension to our house, we are pretty confident that it falls within the PD rights, however we would like to double check this and ensure it's all legal. This is the first time we're doing such a thing and need a little guidance.
Who can advice us whether it falls under PD rights.
Do we need an architect/structual egineer to create plans.
Do we need a Lawful development certificate? Do we need a Building Control Surveyor?
I would much appreciate any help/guidance. I can see all the rules keep changing too so I want to make sure if in the future we were to sell the house we will not have any issues.
