Building Additional Stuff

[Tyhm]

Bakery - several hundred planks, iron, coal, maybe some stone and clay if that's added in later, lots of time
Lumbermill - wood and a lot of iron, lots of time
Mine Entrance - wood and a lot of excavating
Blacksmith - planks, lots of iron, lots of coal, lots of timeWoodshop - lots of wood, lots of time
Dojo/Training Center/Schoolhouse - not so much wood, time
House/Bar - cheapest and fastest building, fairly easy to destroy.
Bridge - 10 planks per part (2 tiles wide), can be destroyed by repeatedly whacking the supports with an axe 100 times or so
Mine Support - 5 planks, holds up the surrounding 20 tiles of mine, rots fairly regularly and must be repaired or replaced or else there's a cave in.
Irrigation - 50 planks, 100 water, as long as it stands (and it only takes 20 or so axe-hits to take down), all corn within 20 or so tiles won't need to be watered.Forest - buy special seeds - just like regular trees, but take 50 hits and provide excellent cover - for both sides.
Wood Fence - 5 planks per part (2x2 tiles) - takes 10 hits, can be chained together to make defences
Stone Wall - 5 stone per part (2x2 tiles) - takes 50 hits with a pickaxe, can be chained together to make defences

Of course, little of this will work without a Masonry skill/shop to make walls out of rock and stuff...^___^
Maybe one store on the main island sells Plans, which you can use as a weapon in a certain place on your kingdom's island to build things...
