Get quotes for either.
If need be, put cedar on the plans and you can alter it later no problem.
I definitely need some quotes.
This is one of the issues, if I need to alter the plan it will have to go back to planning for approval...
Would you put cedar on top of render later on? Or clad a huge wall that is just facing the neighbour?
I was wondering if this will affect the overall permissible depth of the extension if it includes the battens and cedar thickness...
