How do I create a renovation?

[idrivea911]

I have a loose idea for a renovation. I've modelled my as-built house. It is full of artifacts of my amateur user status (small gaps in walls, random bits of railing around my staircase) but that's sort of in the noise that I don't need to fix at the moment. What I'd like to do is hide a handful of interior walls and doors, and put in new walls and doors. I was expecting to be able to assign some walls and doors to a layer (like "as-built remove") and add a layer with "renovation add" and sort of be able to switch between them. Does that functionality exist? Do I need to create a full copy of my layout? I was hoping to avoid that so that as I learn, and fix the random mistakes, I wouldn't have to track those changes across 2 different layouts. I come from SolidWorks product design, where I would switch between configurations of similar designs. I may be looking for a feature that isn't there.

 

I don't want to derail this narrow topic too much, but if someone would like to clean this project up a bit, I am interested to know your rates. I'm looking for dozens of dollars not thousands. For thousands, I'll just keep it looking amateur. High on the list: roof planes are all manual, and funky. Can't get 2nd floor to snap to reference 1st floor. Random holes in walls, probably because I don't know how to build the walls/roof correctly?
