The knowledge and experience of the members here varies greatly and that is what makes it so useful to those who ask questions. The use of multiple posts, casual jargon, incomplete/cryptic descriptions, and URL's without Links tends to limit the kinds of responses you will get to casual "chatroom" anecdotal discussions. If you want more specific, detailed and/or professional advice it is best to ask your question in one post in a more specific and thorough manner. Even if I had understood the meaning of 3/3 the program you have outlined is too incomplete for me to be of much help. For me the design of a house starts with assembling the relevant needs, wishes, restrictions, and limitations instead of searching for designs published by others. If 3/3 hadn't been so puzzling I probably wouldn't have bothered to comment. If you took all of your needs and site features and sketched a rough bubble diagram of how your house might work that would be something I would find find worth discussing.

Thanks for your plan cottagewithroses! I had originally thought that I didn't want to put the washer/dryer there because the windows are low and I thought that changing the windows would look weird on the outside. But if I want to move the hall back to it's original position it really makes sense do what you did. If you look at the picture of the outside, the mudroom doesn't really look like that much of an extension of the sunroom as I originally thought. I think that since the roof lines are different it can work. I looked at my measurements and the mudroom is 103" deep (front of house to back) and the total width from the exterior door to the center hall is around 210". The width of the sunroom minus the hall door space is 112" (whole sunroom width is 152"). We would like to fit the bathroom in a space 57" (deep) by "whatever" since there is an existing exterior wall that would divide the bathroom from the hall. So, in the same space that cottagewith roses put it but with a shower if possible. I would like to open the kitchen or dining room up to the sun room more but am not sure if it will be french doors or just a big opening trimmed out. I can picture the kitchen being really open to the sunroom and putting a banquet in the back corner of the sunroom. We'll probably keep the kitchen/dining room separate because of the fireplace between the two rooms. FYI the front left room will be our living room, the front right room will be our library/music room, and the middle room will be the dining room.

If you are planning to have children someday, will you stay here or move? I can see, with just two adults, why you would use the great room most of the time for your general living space. But with kids, you might want an adult living room and a child-friendly great room/kitchen combination. But if you are planning to move to a different house when you have kids, it would make sense to remodel this house to better fit your needs. Here are some questions for thought: What activities do you do in the great room? TV watching, gaming, reading, surfing the net, board games, entertaining friends, hobbies, crafts, yoga, something else? Are all the activities that you do easy to do in the great room? All supplies ready to hand, electric outlets where you need them, good lighting, table-top space if you need it, etc.? And what activities would you like to do in the great room that you can't, due to lack of resources--space, storage, electrical, table-top space, etc.? If you do have a child while living here, and the child gets your home office, where will all those activities move to? Are they compatible with the activities you currently do in that space? Then think of which of these activities could be moved to the living room or dining room, if you only had the proper support and set-up there. Are you not using the living room because of inherent flaws in the room--poor flow with the rest of the house, bad lighting, etc., or are you not using it because you haven't put in the correct furniture to let you use it the way you want? Clearly, the setup you have now isn't working for you. I think the space can be reconfigured to work better for you, but I'm doubtful that making it one big room is the best way to go. I'd look at plans that still allow you to have one room, however small, in that space where you can close the door and have privacy/quiet. That room can be your home office/computer room, or a library, or a craft space, or anything else you choose. Consider it a "swing" room that can change identities as your family's needs change.

I think you really need to look at the costs associated with moving walls and the kitchen and bath to get an office and curved stairs. The easiest and cheapest solution is to put your office in either bedroom and leave the floor plan the same. Take the money and time you save to update the kitchen and bath fixtures if needed but You still have not shown us what you are starting with except the stairs. Please post pictures of your current space! I think this is a waste of time and money unless you've found that money tree I've heard of. Good luck though. We really DO need more info from you to give you better solutions.
