It took an estimated 5 years to build the Neuschwanstein Castle. Work started on the castle in 1868 and finished in 1872.
From what I can gather, there are no records of Goodrich Castle being built. It is dated as late 11th or early 12th century, but we cannot know how long it took to build.
The first round of construction at Kilkenny Castle was begun in 1192 and completed in 1195. Three towers from that original structure remain. It was added to over time.
It took 14 years to build Alcazar Castle.
Chepstow Castle was built in fits and starts over the period of 1067 to 1300. I did not find any record that indicate how much of this time was actually spent on construction, but the impression I get is that it was not much more than 20 or 25 years.
