How to make a beautiful house

Start off by picking your spot, make sure it's rather big that's why mine is in the water

Make your floor 22 (front) by 17 (sides)

Make your bottom floor 5 blocks with three high windows that are 2 blocks wide and 1 block apart, the top floor should only be half because we want it to be a lookout

Start the second floor, it's the same as the first but keep the half

Make a step down on the second floor

There

Roof

Make rooms

There, even the rooms get windows

Second floor

Only one room

Tada

Decorate including stairs and enjoy
