You asked for advice and here is mine: Modern building codes (and most old ones) require "emergency escape and rescue" openings from ALL sleeping rooms and habitable basements. All window manufacturers have a mark in their catalogs next to the windows that meet the most common requirement. Ground floor openings are allowed to be slightly smaller but it doesn't always translate into a smaller window size. The internet can be highly unreliable for code information because most codes are copyrighted and they also change every three years so you need to buy a copy of the version of the code used in your area and get any modifications from the local building department. As the property owner you will be responsible for meeting the building code and because you will not be using a licensed design professional to assure you of code compliance, you should not rely on any code information from anyone that you haven't personally verified in your copy of the code book. Please take this advice seriously. The next step is to find the window inside sash size from the rough opening size by subtracting about 3" from the RO height and 2" from the RO width. Obviously, you will not be able to use your narrow window concept for at least one window in each bedroom. Your designer will be able to help you modify the house design to accommodate this fact. I strongly recommend giving up the idea of aligning door and window heads unless, of course, they align by chance. Windows should be as high as possible in a wall to bring light deeper into a room. Never let standard door heights dictate where windows are placed; they serve entirely different purposes. Get the windows as high as you can. If a 4" head misalignment bothers you then use 7 ft doors. In old homes both grand and humble this was never an issue. I would recommend a 3-0 x 5-1 RO window with a sash opening of 2-10 x 4-10. The interior stool trim would be 2-2 high with 1-0 of wall above the window. The head opening would be 7-0 high (an excellent height IMHO) and enough above a 6-8 door head to look fine or you could use 7-0 doors. The only other choice would be a 2" wider window that is 4" shorter. I would raise the stool 4" to 2-6 (table height) for increased privacy and keep the window head the same for maximum light. Of course, you could align the doors and windows and keep the stool height at 2-2. Frankly, I would consider a window with a 30 glass width normal rather than "gargantuan". You might find a code compliant casement with a RO width of 2-4 wide. The hardware on some casement windows does not meet the building code emergency escape requirement so you sometimes have to specify the appropriate hardware option. I would take a look at it before ordering it. If you prefer the appearance of narrow windows I suspect you should be using casements anyway.

Thanks for your input. Upon further investigation, I have discovered that a more accurate description of the style of my house may be Tudor Revival?? I am not very informed about different architectural styles, and in fact, I wouldn't be surprised if my house were more of a mishmash of styles. Anyway, here is a photo of the current front of house. I really like the style of door I drew to your attention in the above link. Are you still convinced it would not work? Should I just go for plain sandblasted glass with a clear thin beveled edge in the window of the door?

Sophie - I disagree. I did not design this. I have no pretensions to being a designer and for many other aspects of the renovation we have indeed had formal plans drawn up. [I also know from experience that having an architect involved is far from a panacea .... but that's another story or stories]. For this room we knew we needed to replace the large leaky picture window and instead of replacing in kind we asked whether it would be possible and reasonable to build a window seat and what would be involved. We showed the contractor many pictures of window seats and shared the required dimension ranges (not exact dimensions) from various articles. He said a bay window would take care of it and no separate plans were required. I include the manufacturer's literature excerpt that says their Bay and Bow windows can be used as window seats. It seemed (and actually still seems) a reasonable solution. Projection Window Bay and Bow windows are like a piece of fine furniture for the façade of your home. These unique windows project from your home, creating additional space that can be used for a variety of purposes, such as a window seat or displaying meaningful trinkets. Our vinyl windows (typically double-hung or casement windows) are inserted into a solid frame to create this unique look that adds style to any home. Bay windows typically have three lites (one central fixed lite and two flanking operational lites) at 20-25-degree angles. Bow windows most commonly consist of four lites, all of which can be fixed or operational, set at 10-15 degree angles. The contractor asked us to describe what we wanted to the window vendor as well and we did. We never used the term bay window. We only talked in terms of window seat. The window vendor also did not dissuade us or suggest we needed an addition instead of a window. The window vendor spec'd the window we needed. Given that we have 8 foot ceilings - this would have been a really good place to catch that a 52" bay window wouldn't be long enough to provide a seat at a reasonable height off the floor. I think that's the key flaw here - plus someone's telling us that (unless I'm wrong) we weren't going to get the wood backing. Tomorrow should be interesting ...

I agreed with you mike. I’ve killed my humidifier and seen improvements but it’s still an issue at 48RH at 22c. My first attempt to fixing this issue will be changing the surface tension if the Buck, first by painting it as its pitted with rust from this issue, and secondly by applying a wax (RainX or something similar). I use this trick in the field on pipes using cold water in the summers. It stops the cold pipes gathering condensation by “repelling“ the moisture in the air. I’ll let you know If how it goes.
