you are aware you are asking for what is a paid service for the folks who inhabit this forum, right?

Yep, that's a floorplan. 

Some of the people on this forum won't be so kind, so brace yourself.

I on the other hand enjoy looking at this sort of thing, but all further comments will end with "Hire an Architect". 

I absolutely hate a living room that is used for passage. Everyone that enters the front door makes a diagonal path to get to the bedrooms. Throw some furniture in there and it gets awkward. 

Square homes can be beautiful, but this plan doesn't work well. The dining room has no natural light and a guest shouldn't have to walk through the living room to get to the guest bathroom, nor should there be a clean line of sight from the toilet into a living space.

Talk to an architect about what you need and let them come up with a flow that's less awkward. 

You're going to get comments like "I'm an architect and not a software developer, will you review my code?"

pro-tip no1: just because you think you can design does not mean you should.  

pro-tip no2: design is not just organizing space like it was a spreadsheet.  That's the engineering mind that needs to make and label boxes so that everything has a place.  Spatial quality needs to be considered as well or else you just have another boring box

pro-tip no3: hire, and pay for, an architect if you want design advice.

pro-tip no4: your plan is unimaginative, boring, and very wasteful in terms of spatial organization.  

pro-tip no.5: hire a architect

Anyone else having trouble loading the image? 

Oh damn, looks like the op just vanished... must have realized their error and tried to hide their ignorance/nativité. Fear not, I still had the OG image in a (accidentally opened) 2nd browser window.  Here it is in all it's glory:

It's not a total dumpster fire like we often get... but it's not good either.  I particularly like that the attention was given to 3 tiny sliding glass pocket doors instead of making any sort of sense of the living/dining/sleeping spaces.

I'll take OP at his word that he intends to hire an architect so there's really no reason to argue for the value of that.

OP what you're doing is basically a programming concept, basically laying out what kind of spaces you want and what requirements you have for the connections between them.  That's a helpful starting point once you work with an architect, and you don't need to get it all figured out yourself.

You've given no information about the building itself, your own needs and preferences, or the scope of work to be done so it's totally impossible to evaluate any of this. I have no idea if this is a new build or interior renovation, nor does there seem to be any consideration of how this all looks. Obviously you will have a budget which will impact whether this is all feasible. So regarding the design, no comment. Again, your architect will guide you through this.

Right. Thanks for the suggestion

I think we should keep in mind that some other professions share ideas and ask for advice very often on forums such as stackoverflow. Parametric software users in the architecture business head to forums too for help with Grasshopper. This habit could have lead to some folks outside the design profession to seek advice on forums like this. Of course, there will be some who are looking for free design services and those should be shunned (As someone who is looking to get free custom written code on a programmer forum wil be). A quick first take (akin to simple debugging help in the software business) should be fine. 

Assuming this is an imaginary dream house scenario, and we don't know where this house will be located, I say that these rooms are awfully small on the whole. That may be your intention; I'm not sure.  Also please get rid of the dead-end corridor! 

Typically architects (at least good ones) work in plan, elevation, and section at the same time in order to understand how relationships change as design decisions are made. Space has 3 dimension, but no ceiling heights have been indicated. There is a big difference in a room with an 8 foot ceiling vs. a 12 foot ceiling. Create a basic elevation and section if you intend to keep developing this idea on your own.  If the intent is to develop this idea into a real building, others are right to suggest hiring a professional.   On the whole, I applaud your efforts. This is truly a lot better than the majority of what is posted on this forum.

1st of all, in residential design, you can do whatever you want with the layout, people have preferences, a home design is absolutely personal. The only concern you should have, is how deep of a pocket you got. Anyone can have the layout of their dream home, what other people say about your layout is just their opinion of your design. Much like table reversed, you are the designer and they are the client, they don't like your design and wants change. And remember, if you are looking for custom, you do not want efficient. If you want efficient, just grab some premade floor plan schemes done by hundreds of architects off a residential house plan book.

Honestly you need to hire someone who knows what they're doing. That plan is problematic at best.

I like to think of the hijinks that will ensue when someone enters the kitchen from the dining room at the same time as someone from the corridor. 

There can never be too many toilets.

As one software engineer to another, good luck with your project!!  

I spent years sketching my dream homes, but when I was ready to talk to my architect I left my pencil at home to see what he would draw from a conversation about my program and aesthetic tastes- and I'm really happy with the result.  I do think it is useful to play with your own designs to get a feel for what spaces you want and how you want them to relate, gain some familiarity with standard dimensions of common elements, and to have a better appreciation for the tradeoffs in any floorplan.  The clearer you can be about how you occupy space, the more your architect can optimize the plans to fit your lifestyle- like the difference in code quality when you grok the big picture from the start vs build with piecemeal inconsistent late-breaking requirements.  

As for my amateur feedback, I'm wondering if you're constrained by a small lot and yet a requirement for single-floor living?  If not I'd try to keep to one or two rooms deep and elongate / add L wings / build up as needed- it helps with the natural light and keeps the scale of the roof in check (assuming some sort of pitched roof- important to consider as you design so the exterior isn't hideous).  Also consider the orientation to the sun and relation to outdoor elements- like, most dream homes have some sort of porch or patio and a driveway if not garage?  And trees are nice... :)

Starting from your current plan I'd pull the master bedroom forward to be even with the office and put the gym / playroom in the newly created space (closer to the shower, keeps kid noise away from a nice dinner party, adds more buffer between master and other bedrooms...).  Then run the front porch full length between the symmetrical wings, center the main front door (and really a foyer would be nice) and put a second exterior door off the left side of the porch directly into your office space.  

Then shift the dining room outward to have the exterior wall and swap the pantry/ utility space to the interior, connecting the kitchen to the dining area like a butler pantry.  With the kitchen across the back of the house you could open up that hallway to the back door (maybe an open countertop rather than a wall?) and maybe have space for a sunny breakfast nook along the back wall? 

Just my amateur opinion, hope it gives you something to think about :)

Is it for a door showroom? So many doors!

claustrophobic.

How is the roof plan of this plan? Can anyone help me

Hey, if you'd like send me a PM and I can see if I can be of help to you!
