Kitchen worktop / base unit (Eardington WV16)

I'm looking for a 400mm or 500mm base unit to go with one I already have in my shed so that I can make a bench. I also need a length of kitchen worktop, please. I'm hoping to build a bench about 2.4 metres long. (8ft) If you have anything suitable that you want to clear out, I can arrange collection, thank you.
