Hi again nancy!
There's a little description about what you would get if you upgraded from lite to the full version:
If you like Virtual Families Lite, try the full version, which supports a larger family, more shopping and home improvement choices, and more options for medical care! Have families of up to 8 people living, working, and building a legacy of many generations, all in your iPhone!
This shows that you do have home improvement choices, but not as many as you would from the full version.
Is your store restocking items properly? As in, do the items in the shop change every 4 hours or so?
You need the floor repair kits from the store to repair the holes in the floor.
