Good day Everyone

i am trying to model a house using polygons. currently I am just creating polygon cubes and attaching them to give the outer body of my house. I am battling when it comes to extrude and cut a surfaces to create a window or door frame. I have search for tutorials on how to crate a house in maya but no luck.

Can someone please assist and point me in a direction where i can find good tuturiols on how to extrude and deform surfaces. I found a picture(i have attached the picture) of someone creating a house but I am really dumbstruck on he did it
