I'm building a house & need drawings on how to wire two lights to be controlled by three separate light switches (or four switches).

Need a little more here. Explain exactly what you want. Which light switches will switch which lights? Do you want both lights on and off together? etc.

 

Three way or N way switches are the same as two way. You wire one as intermediate between the other two.

 

You will find this 4-way switch tutorial very helpful.

Note that you will need Javascript installed to view the animations.

 

For three switches, you'll need one "four-way" switch and two "three-way" switches.

Put your two lights in parallel.
