Is it possible to get a set of plans showing how to build this kitchen wine bar?
A question first, do you have a woodshop and the ability to use the tools in it? If your answer is yes, then you don't need plans to build what you need. If your answer is no, then no amount of direction will get you there.
Assuming that you do have woodworking tools and the ability to use them, then it is quite easy to measure out the space you have for such an item and build it to suit your needs. The only additional information that would be handy would be the G-olden Ratio (no hyphen), so as to get the proportions correct.
More specifically on not needing plans, from that picture you can deduce that you have a standard base cabinet and a standard upper cabinet. You can infer dimensions by the wine bottles and glasses, as well as measuring cabinets within your own home. In addition, when it comes to the gingerbread on the unit, I'd recommend taking cues from the furnishings in the area that it will live in, rather than just identically replicating the image.
It looks like that can be built with three stops, all in one day, in my case all over a 5 mile span(and the same case where I used to live as well)
1 - Ikea - two cabinets and maybe the counters and appropriate cabinet doors
2 - Costco/Sams Club - The wine fridge
3 - Orange or Blue big box hardware store - mouldings, beadboard and paint
Add a lot a patience and you can have it done by year's end even if you are not hugely experienced
Great post of helping me. You helped me so much.
