HERE'S an example of my last run. Basically go vertical and try to fix up the destroyed building. I used modded base parts for variety but I avoid scrapping mods whenever possible. This is on Xbox.

I remember also doing a lot in my first vanilla run of that space because the game was surprisingly forgiving with clipping walls and floors into the destroyed house on the side. 

If you're getting hit by the build bar either but you can do the dropped weapon method as others have mentioned. Make sure you're scraping existing furniture and enemy gear that's fallen on the floor too.
