Good point. Where I live now has a similar setup, but the doors to the equipment can swing out into the doorway a bit for slightly more than 90'. I'll have to consider some spacing with this laundry layout.

You may (will) benefit in investing in an architect to assist you in planning out your home. From what little I can see of the plan, I suspect there are other areas that could use some help. You may not notice the problems until the time when you go to sell.

It looks like the staircase you designed is not to code. Winder stairs need to have a minimum tread at the winder part. The experts can tell you how wide minimum is.

Have you thought about nixing the laundry room sink and going for a side by side washer and dryer? We were initially going to do the same as you, stackable against a wall and a wash sink. After much discussion with our builder and architect we decided against it - my thought being I could use my kids sink if I really needed one. and I am so glad I did. Our laundry room is right next to my kids bathroom. I haven't used their sink once in 16 months since we have lived in our house.

The master bath looks perfectly adequate and well laid out.

I would love a real laundry room and the powder rooms looks big enough.

I think the laundry room is big enough for side by sides - which I like a lot better than stackables. You can still have the sink by putting it on the short wall. Or, like Blueberry says, you have a sink in the bathroom right next door.

Mark, you're quite right. Though my father has been a low volume builder
for a few decades and is confident in what we have come up with, I said
early on that it sounded like we could use an architect. The lot is challenging and has dictated the layout.
We started with Mascords 2106C plan, but only a simplified exterior shape remains. It's now mostly a typical ranch.

cpartist, this is a result of me not modeling them properly in the software at this stage. We've figured out the proper, to-code design with our stair maker.

Blueberry, I have! I actually originally planned to do side-by-side with a sink & toilet in that room. Then I nixed the toilet but left the sink, then I stacked the W&D for more cabinets. Frankly I prefer the side by side look too. I was concerned with clearance in front of the W&D (about 3'). Maybe side by side and no sink is the best of both worlds.

Put a side by side set on the wall that backs up to the plumbing in the bathroom. You will have plenty of cabinets on the side wall plus lots of upper wall cabinet storage. It will be a shorter run under the floor to the exterior wall for the dryer vent. You can hang the ironing board on the wall by the door. I would change that pocket door to a swinging door. You should have enough room for it to swing inwards. I don't think there will be a conflict if your washer is a top loader.

"The lot . . . has dictated the layout."

A home design should ALWAYS be dictated by the site.

Which makes tract housing all the more depressing, to me.
I said challenging like it was a bad thing, but really it's made the design decisions simple.
This is my first foray into home building with the hopes to eventually carry on my fathers company. He generally prefers our clients work with an architect. However, I'm able to spend most of my week working on this myself and learning "everything". I often wish I could snap my fingers and know everything an architect does. Some things just can't be googled.

Perhaps if you worked on this project with a good local architect it would be beneficial for you both personally and professionally.

"...I often wish I could snap my fingers and know everything an architect does. .."

Not a problem. Snap your fingers and wait 25 years...:-)

There are of course other things you will have to do over those 25 years . . .
