Kitchen Windows & Bump Out

The windows were installed a few weeks ago, and I need to catch up on the logging the costs.

Here is the bump out we finally decided on, which still needs to be trimmed out and painted. This adds an additional 2.5" depth, giving 7" for the final sill. This will accommodate the pots for the garden window. I will also add a shelf half way up.

Comparing this option with a pre-fab unit

Pre-fab estimates:

• Unit cost $800 from HD
• Window trim $20
• Total Cost: $820

Bump-out:

• Window cost $156 from HD
• Window trim $20
• Framing lumber $30 (it's really cheap right now)
• Piece of T-1-11 ply $35
• Final trim $40
• I already needed to paint, since I added other siding - a quart would be $20
• Total Cost: $300

The total cost of windows was this one, plus the other west-facing one that was a simple install. It was another $156 plus $20 for trim, giving a grand total of $480.

So which looks better? It's on the back of the house, so its really not that big of a deal. For me, I prefer the bump-out. I think it fits better into the overall style of the house. We are going to add an exterior window box as well, which would not be possible with the pre-fab unit.

Having the cost at $500 less is another factor. In this case the window fit up under an existing roof overhang. If we would have added another one on the west side, I would add another $100 for cost of putting in a little roof and flashing.
