To cut a long story short..self build extension, family helping.
"Architectural designer" designs 2 storey extension roof as traditional for planning.
Planning granted with conditions one of which is calcs for roof timbers.
In the meantime builder (relative) sways me towards trusses as they are "easier and quicker to 'throw' up"
So structural engineer didn't include calcs for traditional roof as we had chosen trusses.
Truss designers involved & site visit to measure up.
Then advised we need special adapted raised tie trusses due to existing roof design.
Now builder has changed his mind...they will be too big to 'throw' up.
Doesn't want to wait for trusses, reckons we can't get a crane due to overhead phone lines (although this is debateable in my view, as only our line looks to be in the way telegraph pole at other side of road and neighbours' phone lines don't look that close to me).
Also banging on about a crane permit and road closure but it's a quiet street with an alternate route opposite.
So what are my options? Truss designers reckon ball park figure for weight of trusses is approx 70kg (6" timbers 6 metre span).
No access to rear apart from 1 metre pathway down side.
If I go back to traditional I will now end up paying an extra fee to structural engineer.
