Cost details
Bumping the wall out to build this required the following steps (materials costs)
Total so far is $475. To just do a window (no bump out) would have cost about $230 to this point, so I think its well worth it.
I anticipate the following additional costs:
Estimated total cost: $750 – and well worth it. I think it adds quite a lot of character to the house.
I am planning on re-siding the entire house this summer (lap; board & batten; stone), and I am going to include a rain-screen / drainage plane while I am at it. I will do the first little bit of that when I side the bump-out.
