Have a look at your older posts - I usually come on here (to whine, usually, but sometimes to gloat)...and past posts have been a handy sort of journal - because any more formal method requires non-existent skills such as competence, consistence and a general togetherness which I do not possess (memory is sh*t too). I definitely recall you going on about various purchases...but otoh, you do seem to visit a LOT of nurseries.

Even if you could find a cover that doesn't need to screw in, the plug will be recessed too much to due to the tabs being behind the tile. All you need is a Dremel tool to notch out around the flanges. Then put spacers behind the flanges to bring the plugs out where they belong. You should be able to do this without damaging the tile if you use the right cutting tip and have a steady hand. https://www.youtube.com/watch?v=KXiS4yl3bYY

-All the random jigs, jogs and bump outs on the exterior walls will add to cost and create a complicated roofline. -The secondary bedrooms, bathrooms, closets are too small to accommodate five children total and their storage needs. -The pathway from the mud room to these secondary bedrooms forces the kids to navigate around a lot of furniture in both the family room and game room to get to their own rooms. The constant in and out of kids going to and from their rooms will also be disruptive to those in the family room. -The kids have to walk through the game room/study room to go to another part of the house, which leaves them little privacy and is disruptive to the people using the game room/study room. -The exterior door through the powder room and so near the kids' rooms causes concern for security (and you may not like it when the kids' are teenagers too...trust me). -The sitting room is very small once you accommodate the clearance for the French doors. -The mud room is very small for such a large family. There is no closed closet space that I think you will want for overflow storage, especially considering how small the closets are in the kids' rooms. In the custom homes I design, we try to always include a walk-in closet in the mud room. This is important especially if you live in a climate with a change of seasons. -The master bedroom and bathroom and so large they are inefficient with a ton of wasted space. -All of the built-ins shown on the plan will create a lot of extra expense and are not the most efficient use of the space. There are enough negative issues with the plan, mainly as it relates to flow, privacy and storage, that I think you should scrap it all together. Do you have a builder yet? If so, ask them for architect referrals. Instead of telling the architect how you want to lay out your home, or showing them a stock plan you like, tell them all of your requirements...give them a list of wants and needs. All of the new build homes I work on (I'm currently designing seven) are from custom-designed architectural plans. Given the size and grandeur of the home you want to build, I think it's a necessary investment.

Since it's across from the front door it's kind of an orphan space. You could put two chairs and a side table there, but I don't know whether people would ever want to sit there. A decorated console might not be enough for that space, however. But that's what is usually put in an entryway. So - a chair and a console? I don't have any pictures saved that illustrate this well as this is an unusually large space for a foyer. I suggest you use pieces of furniture you already own to test the concept before buying anything for this space. If you've just moved, stack some boxes to represent the massing of a console or chair to help visualize the options. If you provide measurements of the area it would help the pros here make some concrete suggestions.
