Back in December I bought an Ikea storage cabinet and put it together in my 2nd floor office - where my current in progress Chateau is.
While in a big box store last month, as I was purchasing my soldering iron, I came across a butcher block top that was exactly the right size for this cabinet. I brought it home and fitted it - its perfect!
It is packaged as a counter top that you can hinge, to save space. It comes with brackets to support this type of installation, but obviously I wasn't interested in that. Sometimes you happen upon things when you aren't looking. And, I shopped around online and found it at another big box store for less...bonus!
