In the two places I've lived with such an arrangement, some investigation into the original floorplan has revealed that there's been either an addition or some remodeling going on. And people just took the easy way out and slapped a new room on right next to an existing room, without bothering to add a hallway or the like. In my grandparents' house, you had to go through their bedroom to get to the upstairs bathroom, which was, for a time, the only bathroom in the house, other than a toilet in the basement. The house was built in 1865 and the bathroom was originally a closet. It was the only space for a bathroom. That is, until my grandparents had 7 kids and took the smallest bedroom and made it into a bathroom. They also made a pantry off the kitchen into a powder room, to get a downstairs bathroom. My brother and SIL have a child with disabilities. They needed to either buy a wheelchair accessible house or modify the one they owned. They looked at many houses that had been remodeled for handicap access--SIL was appalled, really, at some of the remodeling. She said it was clear they just added a ramp where it was easiest and threw on extra rooms where it was easiest to expand the house, without any consideration of the flow of traffic through the house or how the rooms would open up to each other, or even trying to match the style/ finishes of the original home with what was going on in the addition. She mentioned bedrooms opening directly off the kitchen, or off the master bedroom, or just a section of the family room walled off to create a room. In one house, they punched through the dining room wall and added a bedroom/bath right off the dining room. And another where they enclosed a porch off the kitchen to make the accessible bedroom, so everyone entering the house walked through the accessible room into the kitchen, unless they used the front door. Which no one does in farm country. They ended up hiring an architect to add on a wing to their house--you can't tell where the old house ends and the new wing begins. They did end up with a dining room with no windows, but it has two sets of french doors opening into rooms with tons of windows and sunlight and you really don't notice. They paid extra to get the addition done right, but I think in the long run they have a house that doesn't *look* handicapped accessible and hasn't lost any resale value.

When we build, there won't be any rooms above our Master Bedroom. At the moment, my almost 13-year-old son and 3-year-old's room is over our Master Bedroom. My 8- and 10-year old's room is above the living room. Their bathroom is between their two rooms. When sleeping in, I can hear every single movement that my 13-year-old and 3-year do. There was carpet in the room which helps with the noise, but I hate carpet and put in wood flooring. If he drops something, I hear it. When he goes to the bathroom, I hear it. When all 4 of them are in one room, I can hear them. Just as this, I can hear every movement in my other boys' room when in the living room. They are very rambunctious and like to jump around. Another problem I have is that the pipe from their toilet/tub goes down the wall which is located between our living and kitchen/dining room. When they flush the toilet or let out their bath water, the pipe rattles in that wall. I know every time they use the bathroom and so do my guests. Most times it is rather embarrassing.

Any suggestion to avoid having the bathroom and living room open straight to the living space. I think you mean having the bathroom and bedroom open to the living space? One of those rooms will have to open to the living space. You can close off the bathroom and have access from the bedroom.

So center the bed on the large wall and flank it with horizontal filing cabinets whose surface can work for printer, lamps, etc. With a sofa at the window I would put TV on the west wall, desk on the south wall. South wall will be less glare from the window though, so you may prefer desk on the west wall and TV on the south wall. In that case, you might prefer a pair of swivel chairs at the window that can turn to view the TV.
