1 - Dormer


I hope its mostly self-explaining.
Note that a little part of the main roof is still visible and was not removed. The dormer shouldn't be higher than the main roof.
In case the blueprint of the dormer roof only appears in the same direction as the main roof, click on custom roofs and then push C. Now you can change the direction.

2 - Bungalow Roof (1)

IMPORTANT:
Both bungalow rooftops mentioned in this guide are very beautiful BUT you should build them only, if you do NOT need the attic- /garret space.
Just click at custom roofs and then push C . Now place the points in the direction in the drawing.
Im sure you can understad how to finish the next steps by yourself.
By the way, place all blueprints and then finnish them with logs. Completing (with logs) any part before all blueprints are placed will make it very hard to build this roof.

Special thanks to -/Naka/- for mentioning, that i did a mistake at the drawing

3 - Circle Tower


Just choose the stonewall in the buildingmenu and push C. And now build little wall pieces of the same lenth and turn you mouse in one direction (left or right) and carry on building the same size wall pieces.
You will get a perfect circle.
Important:
DO NOT PUSH ANY W-A-S-D BUTTONS WHILE DOING IT
You have to build the tower on a custom foundation

BUT I WANT A WOODEN TOWER !
No problem, just place one layer of the stonewall under the wooden tower (it has to do with the length of the elements) and hide the layer with custom foundations later.

4 - Conical Roof

Click on custom roofs and then push C
Now build as little stirpes of roofs til the roof is finished.

It really needs some time to get it working.

5 - Dormer for a door


Very similar to the usual dormer.

6 - Gangway

You can build a gangway with custom stairs.
It's really useful to overlook the terrain around your base - to spot enemies and to attack them with fire arrows.

7 - Terrace

Mostly self-explaining.
Just don't build the complete story and click on custom roofs.
Now the roof is "hovering in the air. Just place two "defensive walls" pieces under it.

8 - Bungalow Roof (2)

IMPORTANT:
Both bungalow rooftops mentioned in this guide are very beautiful BUT you should build them only, if you do NOT need the attic- /garret space.
When having finished the custom foundations and starting to build the walls, choose custom wallsand try to split the wall into 3 elements at the long side of the building. This will help building the 3 same size custom floors later.

When you have done building the floors, choose the custom roof and push C.
Now you place the points in the direction like in the drawing.

It is helpful to start with the red one first: Not only as a blueprint, also by completing it with logs.
Now you can choose which step you want to do next (green/blue). It doesnt really matter, just build both of them first as a blueprint (without adding logs).
When all blueprints for green and blue are placed, add the logs.

9 - Stonewall Gable

To fill the gable you just have to fill as much as possible with the stonewall and then place the blueprints like in the following picture:

It takes some time to make the blueprints fit perfectly, but the result is really nice
Thanks to BRT Cobra

10 - Mediterranean Style Roof


Note that the roof(s) have a flat angle, which is common in the mediterranean area.

12 - Wooden Gable三角木墙

To be honest, it's not the most beautiful way BUT at least much better than an empty/gap gable.
老实说，这不是最漂亮的方法，但墙上至少不会有空的地方

My first try. Defensive walls placed in the middle:
我第一次是让防御尖刺墙放在中间
To bad that the wooden gable will be destroyed too when trying to get rid off the defensive walls after you have finished the gable.
但是木墙会在拆除防御墙时候也同时消失
Placing a wall or other object that looks good and have to stay there is the best way to make one.
Note that with this method, there will be no windows at the gable.
做三角木墙的最好方法是放一条柱（木柱）或者其他看起来差不多的建筑就好。
注意，用这个方法，木墙上不会有窗

This one is with windows. But seriously, it doenst look as good as the first (without windows) example and you have to build the roof that high to make it possible.
这个有窗口的。但说真的，还没第一个没窗口的好看，你还得造更高的屋顶才行

14 - Monopitch Roof单边斜屋顶


And this is how to build it - with eaves only at the front side
下面就是我怎么建的示意图，只在前面有屋檐

建好之后用开口（就是开洞那个，我忘了叫什么名字了）删掉黄色部分

自定义地基：要比实际建筑面积大2.1到2.2倍，如果只有2倍大就不会有屋檐-
a you can imagine, you only have to build enough wallparts to make the custom roof working.
So if you think enough about it before building, you dont have to chop off that much trees.
就如你所知，你必须建好足够的墙壁部分来支撑屋顶，所以，如果建筑之前好好规划，就不需要砍那么多树了

And this is, how it's inside
这就是内景

As you can see, i already build this one with 360 dagree eaves. This isn't nessesary and will make it harder for you to build (mistakes may occur)
The front eaves are pretty easy to make and are really a must-have in my opinion.
如你所见，我已经造好了这个带有360度屋檐的房子了，这不一定是必要，并且可能对你来说有点难（因为有可能出现悲剧），屋前面的屋檐很容易造，我觉得这对我来说是必须要有哒

15 - Arch拱门


If you want an arch for your backyard as a decoration, built it like in the 2nd picture from the top.
If you want the arch for a building (with walls above the arch), make sure you first complete the red marked stripes in the picture above. and then connect the pillars/piers with a straight stonewall blueprint.
Then you can complete it.
如果你想造一个拱门作为你后花园的装饰，按照第二张图那样造
如果你想为你的建筑增加一个拱门（就是墙壁上的拱门），首先你要确保你先完成第二张图中红色标记部分，然后用石头蓝图链接2根石柱，然后就OK啦。

just place defensive walls under the middle and complete them with logs.Now you can set the blueprints for the arch.
就把防御尖刺墙放在中间，然后用石头围墙蓝图搞定
Unrelated:

If you have a large, boring stonewall with no decorations nor windows, try this one.
Self-explaining, i think...
如果你的石墙又大又单调，无装饰无窗口，试试这个

16 - Ridge of the roof屋脊


here are some improvised attempts, to fill the ugly gaps in the ridge of the roof.
这是一些不成熟的建议，用来遮盖略丑的屋脊

this one is literally a table ridge :-)
这简直是桌子屋脊

here you see the blueprints of stickholders as a ridge - senseless to fill the gap, but it will be beautiful - especially at bigger rooftops.
I also got very good results with benches, but a steeply angle roof is required.
这是放在屋脊上一个棍子架，意义不在于遮盖，但是会很好看，特别是大屋顶
用长凳也是不错的，但必须要有一个陡倾角（我也不懂这个）的屋顶
