Minecraft base Update 1

So watching grain in build school past midnight. My laptop is dead from a dead battery and a dead power jack plugin. So what better to do then design a faction base? My friends Agreed that in my minecraft server we should have a village. heres the thing though Everyone has a different design style in mind. My friend who has a family server who cant go online for who knows how long because of a new rule, she lives with her parents and they said she isnt allowed online at all, So she wants a tree house. Faction memebers want it underground. My friend the faction leader sort of likes the house idea on the surface. So Here is what i was think. Build a giant tree house with a hollow trunk that has a cave system. The Tree house is going to be big. Its going to have a big stair case going up to the top where my friend ashley`s house will be. Now back to the bottom. I want the trunk to be huge and a small yet kinda big Giant rock out of no where like cave, I want the trunk to be as big as pat and jen`s challenge games stadium . Now there is only one entrance. On one side is a minecraft system to ride up the tree from the inside and be able to see the outside. I`ll continue on in the next base update. Anyway in the underground everyone is going to have a house. We are starting with roof designs from Grain(<Link to Click). I want a big roof for everyone using the viking style roofing on house 3 but include that little window/room in house number one but remove the roughness. While i like the overhang of the mushroom house i kinda would prefer to use Cobble slabs for the style. Loving the 5th house`s style with the overhang. Now onto the walls, I like using crafting bench Supports with furnances filling in small gaps. Love the stair case in Wall #1 Plus the doors look great for the entrance, Entrance wise, I suggest adding a hopper and some signs as a mailbox lest you use a mod, which i plan on doing but also keeping it to vanilla as close as possible. While i like the angles for the roof, Drop the right angle down abit till its a few blocks maybe 4 or 6 blocks from the ground up,  then curve that up with slanted viking styled roofing including a window thing into it as well but on the curved side. which will make it look wierd. The 2nd floor on the tip that is the over hang and is not curved down, hang it over a bit, make it lean towards the way its hanging on wall #2, Whiles its really cool i like the arch ways and the way the windows are but not quite there. The house itself is empty. The back of the house is actually connected to the wall. Every house has a basement, House and yard is 16 by 16 blocks. Thats all i got.
