I would not. I hate food smells in my bedroom. I would not like going to bed with the smell of dinner's awesome juicy steak lingering on my pillow. Ay chance you can put it off the living room instead?

Makes no sense to me why not off the DR where the solarium is.

Our initial thought was to expand the solarium as this is the natural flow and it can double as a carport maybe. But then we started running into restrictions due to setbacks necessary for the front yard, we face a semi-busy intersection, the back of the neighboring house on the living room side is about 20 feet away, and we were thinking that our backyard is underutilized because you either need to go downstairs, out the front and around the side yard to the back or downstairs and wind your way out to the back. This is a direct route to the back. We were wondering if these are sufficient reasons.

I would put the BBQ off the kitchen or dining room. A balcony off the master might obscure your view?

Absolutely not. Figure out another way.

extend the solarium to the left so it overlaps the kitchen put a door there for your outdoor kitchen. Would be helpful to show the relationship of other buildings, streets and setbacks to your floorplan

I’m with everyone else. I think you might hate it or not use it for its purpose if you did it. Think of all the traffic and shoes going in and out of your master bedroom (especially if you have carpet), not to mention carting food back and forth through it. Also, if you or your spouse isnt feeling well, or has to head to bed early while the party continues, its right outside your bedroom, and everyone gets to tromp right through your bedroom on the way out. And, they’ll all be using your master bath. Out front off the kitchen or dining would be a much better location. You can add higher rails for privacy, cover with lattice or plants or both. Tons of options/ideas.

hmmm. if we bbq off the front balcony and make the back deck more of a private oasis, would that be a better sell?

A private oasis seems like the kind of thing my husband and I would install thinking that we'd definitely use it. Then we really would not use it after the first month. Adding and maintains a deck is not cheap. If it were me, I would think hard about how much I would really use it.

IP, I'm a Realtor and it is a serious objection by buyers to access a deck or patio thru any bedroom. As pointed out above, it is not considered desirable to have a public deck for entertaining that can't be accessed through the public areas.

Is this house existing or are you in the planning stage? If you are in the planning stage, I would rethink your floorplan entirely.

How much space do you have on the side of the house between your house and the property line/setback? Enough room behind the fireplace for the whole deck? Possible to put in a door to the left of the fireplace and run a walkway/porch down the side of the house and connect up with a deck in the back?
