Bill and Christian have just finished installing a 4" X 6" X 12' pine beam which was first fitted into the original old oak house beams, by notching them for a level fit. This will make the new floor going in above them very solid and without movement up or down.
One other 4" X 4" post was added to a corner to reinforce the old beams there (below left).
This is a lovely sight for us. Coming home though, it is very lovely to see my Petunias still blooming this late.
