Yara your house is very elegant and very upscale. It is simple, yet warm and comforting. A perfect family house. If you plan on a child, I'd make a child area to go with it. The child's room is very small so you'll need some sort of play area so it can develop skills. Also, do you have and plans for a nursery? A nursery can be tiny with just room for a cot/crib for the baby/toddler with a potty chair in a bathroom and a high chair in the kitchen or dining area. However, you need a spot for child skilling, (xylophone, peg board, bookshelf, toy box) from toddler on. These can be external from the house or in a separate "play room" where children's clutter won't mess up the elegant style of the house.
My castle was designed with a combination of the Tower of London and Windsor Castle in mind, though I didn't really look at pictures of either of them. Just from what I remembered from a trip when I was a teen. It took me almost two weeks and I still don't consider it quite done. Yes, it will be available for everyone soon.
