Some building but more demolition too...

They have now knocked through from the original house into what will be our bedroom. Bren is standing on the balcony outside what will be the sliding doors that will lead from the bedroom. That bit of balcony will be covered by the new roof that will come out as far as the concrete pillar that can be seen on the second photo, below.

The view from outside shows the pillar just left of centre, the gap behind being the one that Bren is standing in, in the picture above. (Some of you may wish to rearrange the previous sentence into a representation of good English.)
The roof will be the same pitch as the original and both the new and the old will all be done in slate, so the join will be less obvious.
