As a cheap person
I have items that can be moved instead of built-ins. I guess if I had the cash I would spend big money but I don't. Also with built-ins if things change you might be limited on want you can put into the space as a replacement.
So in my humble opinion.
A dishwasher in a perfect world would be great but I use restaurant bin that can be used to wash dishes outside with water from my sink & hot water from by grill burner but in truth I bring the dishes inside to use that dishwasher. Using paper plates & forks etc in the summer helps.
Sink: This I like it lets me clean the cooking tools & my hands & gives me water if I need it . It does not have hot water but I get that from the grill side burner if needed.
Outside built-in or separates...again I am cheap besides there are times I like to move my cookers out of the Cooking patio. I also like the pizza oven in the dinning area so that we can make it from the table if we want.
My grill has a pull up table so I have plenty of room for a staging area.
I like keeping some of my stuff in the garage that I don't use all the time like the big easy. I keep my Weber charcoal & sears gas grill in the cooing area 95% of the time. I also have a garbage can out there.
Fridge: At a time I wanted one but I have a six day cooler & a fridge in my garage so I am all set in that area. I get free ice from the club so the cost is not much.
Fryer: I use the portable one for fries & wings but I guess if I had the money I would buy a larger one.
I have a shed or two lol that allow me to store things outside near my grill area.
We have a sunroom that lets me store cooking tools etc inside that I can just grab as I go out.
I have a small bar inside & another portable one outside that I can use for drinks or serving food etc.
Seating a glass table for six, Eight more in the sunroom, four more in a portable table outside, Two to four by the pool & two more at the bar & many on the lawn.
For me I am really happy with what I have...No it won't make a fashion magazine but it is very functional. I plan what I am doing like most on here & I live by a budget. I would give my setup five stars except for the roof....It really works for me>
OK what one thing would I really want?
A roof over my grill area so when it rains or in the winter I could cook undercover. Because everything can move I could cook with my body in the garage & my grill outside but I don't. I can also use the big easy out front in the winter & bring the food inside. I think Don has a cover & Tommy has that great setup with the cooking palace
or shed
We all have needs so everyone has a different grill area.
