What do you think of these plans for my house?

I'm having twins and I have a six bedroom house. Right now I'm planning how the house will b decorated. I plan on using the master bedroom for my fiance and me. Then, my twins( a boy and a girl) will share a room until they are about 5 months old. Then, I will have a toy room, an office,and a guest room. Those will be the six bedrooms. Then of course, I will have a kitchen, living room, dining room, all the normal stuff. But a lot of things would be wood like the floors. I do not like having a bunch of white on the walls with bright colors. I like the more sophisticated darker look. Then, I will remodel the basement and add on to the first floor. I will add on a huge huge huge room which will be a library. It will have chars in corners and a window seat and tons of bookshelves FULL with books. Then, since my house has 2 acres of land I will have a maze type f backyard except there are signs that lead you to different places. LIke when you first step ot the back door there is an open area with stone pavement and 4 chairs around a table then there will be a fork with three different choices. One way will have a sign that reads: pool, cottage, garden. So you keep walking (and you're surrounded by flowers and then there is the pool(iin ground with some tables and chairs. THen, you keep walking and there is a little cottage with gardening tools but also a small kitchen. After you pass that you turn right and there is my vegetable gard. If you go all the way back to where you start at the open space. there are more signs leading to the stables, towards the woods behind our house, and other things. So, what do you think. I have finished all of this except I still need to by more books and chairs for my library.
