Earlier in this topic you asked if anyone had suggestions on what to make next. I have some ideas.
Great Hall- Bigger building, twice the size of a regular module.
Princess Tower- 4 stories: Harry-Potter-style stairs on the bottom, a beauty-station ( ) on the second floor, a bed on the third floor, and a telescope on the fourth.
Barracks- Very Important! Four small beds.
Chapel-?
Wainwright: Some hammers and a wheel.
Segment of collapsible wall- Because playability
Trebuchet Placement- Corner segment, a short, squat tower.A small library on the lower floor, a weapons rack and ammo on the second floor, and the trebuchet on the roof.
Harbor Entrance: Similar to the FE set, but with arrow slits on either side of the gate and crossed axes overhead. Wooden roof to break up the monotone gray.
Treasure Tower: Nothing on the first floor (maybe a rat or two), a trapdoor on the second floor, and the treasure is on the third floor.
I know you're running out of bricks, but I wrote this up for ya' just in case.
