I would like to claim both towers and make these my first large-ish claim. If similar outposts haven't already been made for me to model floor plans off of, then I would make both towers 4x4 3 story buildings. This building I will make food and equipment storage on first floor sleeping room for 4 guards on the second story and on the third will be room for active duty / dining / daily activities area. I would like to connect these towers via trap door leading to tunnel or sewer.
Claiming. I will make it a 3x3, 3 story guard tower. It will have a storage area on the first floor, a small armory/ equipment room on the second, and living quarters on the third. The furniture will be RM.
May I suggest going with a 2x2, 3 story guardhouse? While it may not seem so small from the outside, it is much smaller in comparison to the other guard posts in Almalexia.
