Extra Wide Baby Gate Help

Andrea • Tommy arrived 12-5-16 ❤️
Hey Ladies! I am beginning to Baby proof my home. I have an "open concept" home and I need a 13'5" (161") baby gate. I want something that will secure to the wall and has a gate door. I can't find anything that is the right size.
I really don't want the "accordian" style because my place isn't big enough for it. 
I am open to buying a custom made one but I haven't found a vendor, have any of you had this problem and found a solution? 
I have attached a photo of my home and drawn on where I want the gate. 
I would like the gate to seperate the family room area from the dining/ kitchen area. 
Thank you so much for your help!
