I'm not in Cork so can't help with that side of things! We've changed door before on a house, then renovated a few years ago on another house we bought, both times we went with an Apeer composite door & were delighted. I did not like the Palladio doors, looked cheap & seen a few reviews I didnt like. I'm a front door person if thats a thing & think the front door should be extremely decent, look good if not better than windows, & I live by the Atlantic so need something solid & that can take a beating from the storms we get!
I think we paid something in the area of 2500 maybe for the first door, door & 1 side panel of glass. The next door was about 3k but it was door and 2 full side panels of glass. The Apeer website has a bunch of Cork suppliers, so best to ask them about sizes and worth getting a quote anyway!
