Level Up (A5E) Stronghold rules incomplete?

[Lord_Stormy]

Did I miss something or does it seem the stronghold rules skipped some stuff?

Namely it doesn't really discuss upgrading an existing structure or mixing urban and rural strongholds? I really want to make my wizard tower surrounded by a vineyard in the mountains. I know it says sub-holds have to be half the size or smaller, but mixing acres and square feet isn't discussed.

Biggest thing I noticed is there nothing about build and upgrade time.
Also no specific upgrades above and beyond general furnishings?

An acre is 43,560 square feet.

An acre is 43,560 square feet.

Since they make a distinction between the two categories, my thought was that are on different scales and shouldn't be 1:1.

One thing that got me was no time given for building new, or at least I couldn’t find discussion of time
