My house, a semi, originally had an open porch.
When I moved in, the porch was enclosed with a pair of glazed doors opening in, with a fixed glazed panel on each side. The doors are a tight fit when using one, but fine for normal pedestrian, both open for moving boxes.
Several houses had identical porches, so either it was an add on by the original builders or someone hit the estate soon after it was built.
My next door neighbour replaced his with a patio door. - could that be an option?
He could lock his, but didn’t often as he retained his front door. Is this a porch or extension?
