There's nothing like a old house for character. Why not add on to the house you bought using decorative elements from the 1920's to keep the house within the same look. I'd strongly suggest you take a look at some of the old house boards and read up on old house restoration. IF you do decide to restore rather than destroy leave the windows alone. Despite what the sales folks are going to tell you you aren't loosing heat thru those old windows if they are properly maintained. Riping them out you will loose much of the houses character and charm. Replacement windows are just that something you will be replacing over time again and again.

What about color on the exterior side? Were they priced out with standard sized Andersen windows? What brand of vinyl windows does your builder or you have access to? Sometimes the recommended brands can be hard to get even though they are available in your area. I would see what's available, price them out then make a decision off of that. Fiberglass tend to run more than both of these but you may be able to get a good price on the Marvin Integrity especially in standard sizes, be aware there are 2 lines available, one is all ultrex and the other is wood interior/Ultrex..

Take a look at something with all the spaces you're considering in a more consolidated, better laid out design with a proportional roof: https://www.thehousedesigners.com/plan/southborough-cottage-house-plan-5558/ Make a couple changes -- note image below: - Pull the (green) great room out so it receives natural light ... put in a single French door between the great room and the covered porch (purple), which is now more square /less rectangle ... better for setting up an outdoor seating area, and it doesn't block your light. With this in mind, I would add windows to the SIDE of the kids' rooms. I'd then add a patio, which could be accessed from the screen porch, the great room, or the master bedroom. - Re-do the master bath (red) and master closet (blue) so that the bath receives natural light. You could also have a door connecting the closet and the laundry -- so convenient. I'd probably make the laundry /closet a bit deeper to allow for a folding cabinet opposite the machines. - Add your second garage (yellow) to the side ... the yellow garage would be slightly larger than the existing one. (I actually wouldn't do this, but you say it's a must.) - The breakfast area isn't 'specially spacious, but you could easily stretch your table out into the great room when you have a big group. - With the hall bath available for guests, I'd make the half-bath into a lovely little desk spot ... so convenient off the kitchen. Or a pantry. - It's not perfect, but it still gives you your craft space in the area that's now a dining room ... or you could use one of the kids' bedrooms as your craft space and put the other kid in the upstairs bonus room. Note that the flow works better: the hallways aren't long and twisty-turny.

well of course install would be bit more if you're comparing it to a click and lock type of vinyl. But are you aware they also have floating click/lock wood floors?? doesn't have to be a glue or nail down. this wouldn't be any more to install and you'd prob find exactly what you want, color-wise. https://jenwoodhouse.com/how-to-install-engineered-hardwood-flooring/ you could always install it yourselves. malibu wide plank click/lock french oak- home depot https://homedepot.sjv.io/kv990 BuildDirect And I'll bet you dollars to donuts the average homeowner would like this much better than vinyl. (but I guess it would depend where you live. somewhere in podunk NE prob wouldn't care as much as a metropolitan city area. Same issue w/home prices. places like MS where you can buy a home for 80K isn't going to be the same in a city where similar homes go for 600-800K. The latter will expect wood as opposed to vinyl) So if you live in a city where homes are super inexpensive, then I guess vinyl wouldn't be an issue. I mentioned this type of engineered flooring because you're the one who has said they've looked for over a month and couldn't find what's in that picture. this one is the finished flooring from HD from JenWoodhouse.
