A bit of expert guidance would be much appreciated as it's a while since I've gone through the process...
I have Planning sorted for a single-storey rear extension. I now need the building regs drawing and party wall process to be all sorted by February, which is when my builder will be available.
I know which builder I want to use so that saves time with the tender etc.
How else can I shave a few weeks off the timeline?
Can I brief the structural engineer to start today (he's taking 3-4 weeks at the moment), or is there anything else I need to consider?
Can I start the party wall process before the detailed drawings are ready, or do I need to wait? And should I ask my neighbour today which surveyor he wants to go with, if I already know that he wants to use one?
