How a longer First World War might produce Admirals, G3s, and N3s

How long would the war and treaty negotiations need to last for Britain to build four Admirals, four G3s, and four N3s?

War to about 1920 could yield the Admirals, while a settlement delayed to roughly 1924 could permit G3s and perhaps initial N3s.

If the First World War continued toward 1920, Britain could probably complete the four Admiral-class battlecruisers. G3 and N3 would follow later. Delaying the treaty settlement until about 1924 could allow the G3s to proceed and perhaps one or two N3s as well. Completion of all four N3s requested in the question remains beyond that estimate.
