Conservatory Build under PD - can we knock new external door?

[craynerd]

Evening,
Our home has a nice sized garden which wraps around the side of our house. I would like to put up a conservatory on the side of our house which in terms of size and structure should comply under permitted development. However, this would require a new door being knocked through to gain access. I would appreciate advice as to where I stand with this?

I seem to recall that an external door should be erected as entry to a conservatory but I can't find reference to this. I would certainly much prefer a good internal door if it was allowed to make it more part of the house, but is an external door my only option? Would building regs or planning permission now be needed based on this new door?

Thanks for any help you can provide

Chris

Under b/regs you need separation from the house via an external grade door, or else the whole conservatory will need building regulation approval - which would be difficult to achieve.

Its in the many guides to building regulations and conservatories, and from Part L1
