We had thoughts of tearing down the entire west side brick wall and add insulation and siding, but it didn't fit within the budget. Instead the mason was there for two days fixing the new hole in the wall and the messy edge towards the the new wall. The old window had already been replaced and the framing had been done from the inside.
Nicely done! Even the odd 3D pattern was recreated. The brick guy had never seen that before. It is also quite unusual to have brick on the side of the house and siding front and back. Now, we only need another window installed and some siding.
