I'd like to seal my front door by building a front porch with a sealed door. Now the house already has a sort of "opened" entrance porch or canopy before getting to the front door. Other houses in the estate have just enclosed this opening with a pvc framed door etc to the outer most edge. Though as things currently stand one would still have to step up into this newly enclosed porch by more than 15mm (id say 80mm). This is the current rise of the step. Would this break any regulations?
Secondly, the depth of this porch area isnt sufficient to allow for an inward opening door, which would be idea, so I guess the only other options would be an outward or a sliding door?
I know it would be more costly but could one extend the area with what I'll call a u shape shell and then to rebuild the roof accordingly?
Thanks
