We did make some changes to our house plan, but they were mostly on paper. It's much easier and cheaper to change things on paper. A neighbor mentioned the lack of windows on our kitchen wall--and we were the ones who wanted cross ventilation--so we added a window and subtracted a cabinet. Then we made a last minute change in a bathroom. (Sometimes, however, the changes don't make it to the sub-contractors' copies, but when it's not your fault, you don't have to pay for it. And a house inspection can end up changing your house plan and catch mistakes. Inspectors caught a mistake with the framing of mother's back door and made us move electrical outlets to an outside wall in her back porch room.) Speaking of bathrooms, we learned about resale value when building, but we decided we only needed three bathrooms. I did not need a bathroom off my bedroom; I use the guest one off the Great Hall; it's right across from my bedroom. That decision gave us a big closet off the Great Hall. Resale value is why we put in the dishwasher. We weren't going to. Disposals, we found out, require a larger septic tank and maintenance. We compost anyway. So, if buyers want one, they'll have to put it in. It's always a matter of choices.
