I'm fed up with my limited livingspace so I decided that somtime in the spring I'll get bankloan and build myself house.
One thing that also saves money is that there are plenty of builders in my close family.
Under the house I'm gonna build basement and as building that won't be that expensive, I'll probably go big.
Maybe something like this

Each room is 7 by 4 meters, staircase being 3 by 3 meters. Height 2.5 - 3 meters
Little explanation about the gameroom:
Green parts are 40-60cm deep shelves
Purple parts are 15-20cm gameshelves that are also doors.
I might alter the layout bit and add indoor pool.
