At the front of the house, there’s a gang of switches, and the electricians had to demo the plaster in this area to run the new wires. All of the casing around the doors and windows has been removed, as well . . .

Our powder room wall is more infrastructure pipes and wires than it is framing . . .

To the south of the powder room, the pantry walls house plumbing and electrical, including bundles of electrical wires running up the end of the new wall from the electrical panel below to supply the second floor.

Rough-ins for the south end of the kitchen:

And electrical, gas, and the hood vent to support elements on the west wall of the kitchen:

The kitchen walls also house hydronic infrastructure elements. Here, the red, radiator supply and return lines for the master bedroom travel up the kitchen bump-out wall:
