An old problem with trees

I have recently had to do a repair on a farm near home. A couple of hundred years ago a line of trees were planted, close to, but at the time seemingly far enough away from the wall not to do any damage. Nowadays that estates do not want to chop down beautiful mature trees I often have to deal with the long term result. This involves bridging large roots and sometimes putting in a lintel to give the tree freedom to grow for another fifty years or so.
The entry on 17th March will be another example from the work of Danny Woodward.
