My house is undergoing a renovation of the kitchen & main bathroom, as well as a small addition! 

Upstairs -- kitchen & mud room -- blue tarp covers opening to dining room...note arched doorway to hallway (this is now gone)...triple window in mud room and box out window (over sink) at the front of the house, inside kitchen wall with short wall where wall oven will go.

Downstairs -- music room -- white-ish fabric is attached to ceiling to hold up the blown insulation.  Normal insulation on walls & black vinyl which is to help with sound proofing.

Stairs to basement (that's just a miscellaneous board across the opening).
