Moving or "centering" windows for the exterior may or may not have a positive effect on the interior. You are not playing Tetris.

If you don't have the quoins, centering the window on the brick will also center it on the door, is that right?

Why is the builder deciding and not your architect?

When you said the builder moved the window I thought it had already been installed. Is that the case or is the builder also the designer?

Builder is also the designer. Should have clarified that. We are thinking to focus on centering the window to the interior wall of that bedroom, and whatever it is on the exterior that’s what it will be. Which we believe is option 2 there, but will confirm with designer.

Since this is in the design phase, redesign that whole area to eliminate all those cascading roofs with designed in water damage. Get a better architect than a builder who only halfway knows CAD. Or building.

I was just thinking what Celadon wrote. Why does that elevation show 4 rooflines? Not only are they giving a “welcome mat” to freeze-thaw cycles with all those crevices, but also each one adds unnecessary cost, and can create interior design problems in the rooms with all those ceiling changes.

You might want to post your full floor plan but if you do, be ready for honest advice of what is not good.

WARNING: Posting your entire floor plan opens you up to facts you may not want to know, but should. Be prepared for suggestions that will make for a better design. Keep a thick skin, open mind, sense of humor, and a glass of wine within arms reach. You may not enjoy it, but everyone else will and you will be better off in the long run if you heed well the advice.

The problem is trying to design with a computer construction drawing. An architectural design drawing should show the correct materials, colors and shadows. A 3d model would allow you to add colors and shadows and rotate the house to see what it might really look like and test different ideas. Its cheap insurance.

Rethink the quoins too. That detail creates a vertical emphasis not needed. Or just do same brick just for variation. Agree with other inputs above. I think the upper right window is also too high. Should have some 3-4 rows of brick above that window or change shape of window completely.

I think the OP said at the top that the quoins are the same brick.

I would center the window above the door. The asymmetry of the window inside the room can be addressed with decor. The lack of symmetry from the street would be disturbing to the eye.

do you have a side elevation? I am very confused by the roof. It looks like cascading hipped roofs?

since I can’t figure out the roof I’m not sure. But I’d take off one layer of roof and then the aligned window looks good. Forgive the ridiculous edit

I agree; from the elevation drawing the front facade makes no sense at all as if the pieces came from elsewhere and were just stuck on. Or perhaps the front portico was simply added last with no consideration for the rest of the design.

The important thing to learn from this discussion is that the location of the window is the least of the problems with this design. Find a professional who understands Neo-French Eclectic architecture and can provide a 3D computer model in color that can be rotated and edited.
