My first house was made with bricks and it was big and had a roof (my dad helped me make it)

Honestly I just make rectangular wooden boxes as houses

nice, my first looks exactly like the image.

My first house was actually just me joining my friend's hardcore server,him putting us into Creative mode,me going into his house while he was building it and digging a space underground where I put all my stuff I wanted
I had a mini pond of Salmon
And a tunnel leading to a shed made out of wood where I kept my dogs,I carved the tunnel out myself while looking for my dog's name tags
