[DAVES]

We bought a new completed home. Plus to me. I would blame wife but probably true of me to. I need to see it. Choosing say a color of granite. Oops it does not look as I thought.
Our home is stretched. The same model was built with and without columns in the living room. We wanted and bought one without columns. We've been here going on eight years. I think your real question should be not what people add on average but what you want and what it will cost.
Storage space is limited. I don't think any homes around here have a basement. I expect if you can get one it would be an indoor swimming pool due to the amount of rain and the type of soil. I saw a post with prices for a golf cart garage. We have one and a two car garage. So much for plans. The golf cart garage has my table saw etc.
The golf cart is in the second garage. That price is for the golf cart garage. You need a bigger lot to be able to put it on.
The cabinetry. We do not have the baseline but the quality is not what I would want.
I had to reinforce the cabinets as you/we put more in them than we should. A neighbor had them collapse.
