Overall it's not a bad plan. There will be lots of natural light which is the main thing I always look for. I like that there are lots of windows. Bravo.

Regarding the notch-o, if it were me, I'd make the pantry a bit narrower (5' wide total) and longer. I'd get rid of the notch-o completely as all that does is add cost to the build. This would make your dining room longer which is never a bad thing.

I would also flip the washer and dryer to the opposite wall so if you run a load at night you're not hearing it in your master bedroom.

Speaking of your master bedroom, where will the bed go?

The master closet will have lots of space that can't be used because clothes don't do well in corners as mentioned already.

Just an FYI, in your master bath, your width is actually 6'8" wide. Assuming both your makeup table and your vanity are both 21" deep, that will leave you with 3'2" between the two. Not a problem if you use the vanity closer to the tub but it might be an issue if your better half uses that side for the vanity.

The kitchen needs work. The last thing you want is a fridge breaking up counter space. What are you planning for in front of the window? Will that just be cabinets or is that supposed to be a window seat or a breakfast sitting area with a banquet?

Bravo on having really nice aisles in the kitchen. In fact, for me they'd be too wide but that's a personal decision whether to have them 4 or 5' wide.

I noticed you tried to line up the fireplace with the sink and with the cooktop. First no one can possibly look at the fireplace and the sink and cooktop at the same time since they're on opposite ends. Secondly, symmetry in a kitchen is highly overrated since the only time you'd ever might notice they're symmetrical is when you're standing dead center in front of the island. How often do you think you'll be doing that?

To give you an example, my sink isn't even centered on my island but my pendants are. Not one person has noticed the discrepancy. Not even me, and normally I'm very um...precise.

I would highly recommend you post your kitchen in the Kitchen Forum for them to really help you with layout of the kitchen. It's almost there.

Agree with Doc about the landing in the garage.

Also looking at Gavin's room, his closet will have lots of wasted space. It appears he will have about 18"-2' on either side of the door in a reach in closet. How will he get to those things back there?

Also one other thing to consider with the kid's bath is that the toilet is right up against McKenzie's room so if Gavin has to use the toilet in the middle of the night, it might wake her. Believe it or not, my DH can hear our toilet from our master bathroom and I have a hallway and my master closet between our bedroom and the toilet.

I wouldn't do a pocket door on a child's closet. They don't hold up quite as well as a regular door. If it were me and my child, I think I'd rather make the space a reach in closet with the niche for the seating opposite like shown. Since the doors would be closed the majority of the time, it won't interfere with her being at the desk. Next to it could be a bookcase. Or if it were me when I was growing up, I would have loved a sitting bench with a bookshelf.

Lastly, with young children I absolutely would not put in a ventless fireplace. Please do yourself a huge favor and read up on them. If you can't put in a vented gas fireplace, put in an electric one. Dimplex makes one that is so real looking I had done a double take when I saw it. I didn't put it in because the only shape they had was a linear one and I wanted one that was more old fashioned looking, but if they had the shape I was looking for, I would have given up the vented gas one I put in in a heartbeat.

What is upstairs?
