We are removing the roofs from the original pre war house (Hip roof and tile), the masterpiece that is the 1970's extension double roof at the rear (two gable roofs - cathedral ceiling - colourbond) and the less than optimum add on to the verandah and pretend it is an ensuite roof (skillion - very low - colorbond).
We want to put one gable roof over the whole house. Ideally all load bearing to be on external walls. Will be steep enough pitch to allow for an attic room.
The problem - it is 12 metres wide (and we need to allow for overhand) and 20 metres long - and is going to be fully tiled (so heavy). Span tables as I am reading them seem to suggest that we cannot have this span.
We will go to drafting asap but are trying to be as precise with our brief as possible to ensure that we can keep professional fees down, and to enable a quick design process.
Based in Perth - our local planning policy allows building up to 10.5 metres and no limitation on pitch. Current wall is 3.2 metres high - so not going to be anywhere near maximum height!

We would be incredibly grateful to know if anyone has experience designing or building a Gable roof with a of span 12 metres by 20 metres. Just want to know if it is posisble really?
