This was my first self-designed piece of furniture, it was a part of our living room in different apartments for more than 5 years.
This is what it can look like in the end.
The basic structure of the bar is easy: a large (purple) and a small (green) piece of plywood form an L-shape. A tabletop (yellow) is on top, table legs (orange) add stability in the back of the bar.
You can build a bar like this in any size you want, wider, shorter, higher. Whatever fits in your apartment.
First of all: Material needed. Lots of veneered plywood & some table legs
We got the plywood directly from the hardware store. They cut it for you to the dimensions you need!
You'll need lots of screws & L-brackets.
Assemble the plywood...
...add the table legs...
...and you'll end up with a base like this.
From the back it'll look like this.
Build two of these, put one on top of the other and attach it to the bottom section using L-brackets.
In the end you'll have a nice bar...
...with a lot of space for glasses and bottles behind it.
We used bottle holders from IKEA ...
... and glass holders from IKEA as well.
Cost: 3€ per table leg + 35€ for plywood + 10€ for screws & L-brackets + 12€ for interior. Total: 75€
