First of I would like to make it clear, that I am not the rightful owner of this video, nor the creator of the blueprint for this house.
The house is simply good looking, and a great starter house.

The layout for this guide is simple, step by step text guide and then a video. Recorded by "G Gamer" who is the guy, which made the layout for this house.

This is how the house is going to look like

Start off by building the floor, which can be built with any kind of wood. But I recommend the basic "Wood"
The floor is measured by 30 blocks length. When done with the floor, start building the walls. Walk out to one of the floor ends, and count one block in. Now place 6 wooden blocks standing upright ( on both sides ). And build the roof by continuing building from the top block, to the other end of the Wooden blocks ( which are standing upright ).

Then destroy the 3 lowest blocks of the walls, on both side of the walls, and build a door. Walking through the door, you'll build a fringe, 3 blocks height. Just like shown in the picture.

So far you'll end up with a structure looking like this ( if you have done it correctly )

Now add another layer of wooden floor on top of the roof
Then walk into the house and place a block on each top corner.
Now make a hole in the roof, with a measurement of 4 blocks ( width ). You can make the whole anywhere you desire, but I recommend making the hole on the right side of the roof. When you have done that, you shall place platforms which are allowing you, to jump up through the hole.

Now you shall jump up onto the roof, and build a two block thick wall ( on each side of the house )
After that build a two block thick roof, and place a top block in each corner.
If you have done it correctly, you have got a room which has a height of four blocks.

This is the result so far

Start off by making another platform, which I recommend building "over" the other platforms.
Then walk out to the end of the house, and place two extra blocks to add length, and place two blocks. Now place an extra block on each end of the house, to make it look "pointy"

After that place down blocks with the width of three, on each side of the "roof". Then place two blocks on top of it, ( make sure the blocks are placed inward to the house ). Keep doing that, till both ends hit each other forming a spiral. ( see the picture for further information )

The house so far

Now for the finishing touches, use a hammer to polish the corners like shown on the picture. And place walls "Background"

Congratulations you are now done with the house, this is the end result.

"I would recommend slime banners as they can work as curtains and give you a damage increase against slimes, which is good for early pre- hardmode. Sunflowers help too, as they give you the "Happy" buff which increases movement speed and lowers monster spawn rates."
