Thanks for all the suggestions, quite a lot to think about! I think as it's quite a low arch I may have to go for an arched door rather than the square UPVC door set in to a frame.
Carpenter it is.
I have a porch area recessed in the front of the house with a brick archway. I want a glazed door to enclose the porch so we can keep shoes etc in the porch.
As this would be secondary to the existing front door I do not want to have external grade locks and glazing etc but I don't know if...
