You want to lose storage space and have to buy all new floors?

yes,,I will lose storage..but thinking I could use this piece to make an island? After the wall is opened up

No, you can't. You will have to redo everything. And taking down a wall is not a "just" project. Figure 5-15K per wall, just for the wall taking down if it's not structural or simple structural. Then, there are the associated costs that go with the wall going down. All new floors for the now one single room space. All of the electrical in that wall has to be completely rerouted, including the switches. All of the HVAC too. And the plumbing.

Then you have a nice open blank space where all of the new cabinets, countertops, lighting, sink, faucet, and painting can happen. Add all of that to the cost of "just" taking down the wall. HGTV is fake. Fake project, fake people, and fake numbers. Construction costs real money, and needs skilled, licensed people involved that pull permits.
