We are doing a similar design. For us it's all about natural light. Our windows face East and we want as much morning sun as possible. The windows will look onto a deck/courtyard which is across from the master bedroom (u-shaped house). So it's not out looking at the back yard greenery but we will make the courtyard area colorful with potted plants and such. The windows are 36"x3= 108" This other picture is my inspiration picture. Those windows face East as well and look out to the side yard - essentially a fence. But it's about the natural light that comes in. Those windows are 32"x4 = 128".

I'd like to see them wider and sitting on top of the lentil. This would be expensive due the brick and header sizing. Coud make them the same width as the ones below it . Sometimes it is better to do the siding and window together.

I recommend matching panels over shades for both windows, such as below. Note the rod placement and length as it relates to the window.

You should be asking more questions than just windows. Such as why you'd put the pantry on an outside wall and on a corner. Corners are best for public rooms and bedrooms so those rooms can get windows on two walls. Also why you're placing the laundry room so far from the bedrooms considering bedrooms are where the majority of the laundry is generated. Also why do you have such a small enclosed kitchen? I'm not saying you need an open kitchen but this one is not even laid out well when you consider where the sink is in relation to the dining room. The sink and the fridge should be closer to the dining room and the cooktop should be the furthest away and out of anyone possibly walking by. If you plan to have a seating grouping around a tv in the living room, where will it go considering you have entrances on two sides of what is just a 5'-6' wall. And it means you'll be walking through the seating area to get to the master bedroom because NO ONE walks around. Everyone takes the shortest route. Why do you need an 18' long dining room? That's lots of wasted space for what? What is the wasted space next to the tub in the master? Where will the bed go in the master with all those doors? The mudroom will be tight for more than one person when you consider the bench/shelves are 18" deep. That only gives you 4.5' of walking space. Lastly the laundry room is 6' wide. Machines stick out a minimum of 30" and usually a few inches more. So that means you have a grand total of 4' to maneuver in the laundry room. If you have side loaders, that means if you open the doors you can't even maneuver around the machines in the room. Like I said, windows are the least of your problems right now. The best houses do not have fat roofs like your house. The best houses are designed in an L, I, U, T or H shape. The best houses have windows on at least two walls in all public rooms and all bedrooms. The best houses do not have utility rooms, pantries, etc taking up prime real estate on corners. The best houses are only 1-2 rooms deep and that does include porches, garages, etc. The best houses have a central "spine" so it's easy to figure out how to go from room to room.
