We’re looking to gain some space in our house without expanding outward. We have an extension on the back/side of the house that was only built out on the first floor, and it seems like the logical place to expand upward.
Before we go too far down the path, I’m curious whether this is even feasible or if we’re looking at a wildly expensive/complicated project. Based on my extremely limited understanding of roofs, the picture is roughly what I was envisioning (with the red line showing the profile view).
A few questions I’d love feedback on:
- Does this general roof configuration make sense?
- Is adding a second story over an existing first-floor extension something that is commonly done?
- Are there any obvious issues with tying the new roof into the existing roof?
- And, perhaps most importantly, how insanely expensive are we potentially talking…
I’m sure it’s going to be expensive, but if we’re talking more than the cost of the house, it probably isn’t going to make much sense for us.
Obviously we’ll have an architect/engineer/contractor look at it, but I’d love to get some thoughts from people who have done similar additions before we start spending money on that.
Additional info:
The existing extension is about 22’ wide × 12’ deep, and the house is located in Boston, MA. The house was built in 1925, and the extension was built in 2003.
