I am looking at a colleagues plans for renovating his house and suggested that he might consider an outward opening external door. The idea is that it will help with the internal layout.
These things don't seem to be in very common use except on conservatories perhaps. Is there a practical reason for this, or are they more expensive than inward opening ones?
The door will be inside an open porch, so protected to some extent from the elements.
Thanks
Phil
