When we remodelled the kitchen at our old house, the designer made a measurement mistake that made it impossible for us to reuse the old island top on top of the new island base. We put the countertop in the garage and every once in a while, I would call up our favorite contractor (whose heart is in carpentry) and ask him to build us a base of some sort. A few years later, we now have a repurposed quartz countertop coffee table!
He built the base from maple scraps he found at our local Habitat store, and I think it goes beautifully with the dark table top.
We found the auditorium chairs at Wool Hat; the store owners got them from an elementary school somewhere on the eastern plains. I recovered the seats with fabric from old curtains, and to prevent the chairs from tipping, our contractor gave us some teak slats (saved from a remodelling job at a 1970s house) that we screwed to the base. The chairs are remarkably comfortable if you are the right size, say a child or a small adult 🙂
And now, the basement really is finished!
