I used to sell and rebuild Fire Ruins, Shrine of light etc as they cost the most to level up again. Stonehenge was also a good one as it used up a few resources. Maybe, depending on how much storage you need for your gems, a gem storehouse would also work well as they take a lot of resources to level up.
