What is your question?

It looks like the house is at grade so it isn't a cantilever, you just extend the foundation out. And put in a steel beam to support the second floor. That 2' will cost as much as the balance of the remodel.

You just spend 50K+.

@M Miller, can we tie into the existing 2' X 10' cantilever and extend it an additional 10' along the back of the home? And are we able to do a cantilever bump-out for a total of 2' X 20'? Would we have a header that went across the entire span that was in the home or could we do something else so we didn't have a large steel header/etc. in the kitchen?

@HALLET & Co., the house is not at grade (has a full basement) and there are two cantilevers that were built when the house was constructed. They sit about 12-18" off-grade, one is off the kitchen and one off the home office/library (see the photo with outlines in red). I'd like to extend the cantilever off the kitchen across the entire back wall of the home (the kitchen). I just don't know how we support the second floor when the open ceiling will span 20'? A steel beam might work, but I don't want it below the ceiling. I'm thinking this isn't possible? Thanks for a reply that was actually helpful!

@DeWayne, we're budgeting $150K for an entire first floor renovation. I'm wondering how much this 20 square foot bump-out adds to that budget. I'm just wondering if cost-wise it makes more sense to go even bigger and if it saves us any money to stick with a 2' cantilever bump-out. The village makes poured foundation additions a real nightmare.

Tim, people hire architects for this purpose. An architect will have the answers to your questions. A top notch licenced contractor, should also have the expertise to help.

A bump out on grade is not a cantilever. It's a fully foundationed section of a home. If you want the upper to overhang the lower by 2', with no visible means of support, then that is a cantilever, as the support for that will be back in the main house, and extends into the bump.

Live with what you have.

@darbuka totally understand, but there are hundreds of architects and engineers who are on Houzz. I was hoping to just get a response stating if it was even possible to extend the existing cantilever bump-out before contacting a local contractor.

If your budget is 150K for a mid grade kitchen and the bump out, that might be feasible. But, that's it. You aren't getting anything else.

This is not a financially sound option.

@Love Your Nest, what would be a financially sound option? We purchased our home in 2018 and do not want to move from our current neighborhood, mortgage balance, or mortgage rate. This will be our forever home and homes are currently selling $200-$250K more than when we purchased.

Design a galley kitchen with peninsula. As is probably the current design. Normal home appreciation only puts money in your pocket when you sell. Remodels take money out of your pocket. You will get no additional bump from a bump. It would actually lose you money, because it is not very appealing inside or out.

That’s a terrible kitchen design that doesn't need $1 spent on it.

Buy a different house.
