Oak frame is a jigsaw

The guys from Welsh Oak Frame spent the morning covering the brickwork below the damp with polythene to protect it from staining by the tannin in the wood, they then fixed the sole plate on the damp proof coarse to stand the Oak frame on.

After a decent sunny morning the rain has returned but the WOF guys are working in it as they have to get ready for the crane in the morning. Each piece of oak  has a letter and number allowing the framers to know which  part of the frame each piece belongs to so they are spending the afternoon identifying the Oak they need to get started.

Away from the frame I have been looking in to which rainwater harvesting system I am going to use, I spoke to WPL who market a home package which comes in at just over 3k for a 6500 Lt tank which seems a bit expensive but as I have only just started looking I have no idea really. I would be interested to hear anyone elses recommendations or experiences with harvesting systems.
