Timber Framers Guild Forums General General Forum Questions Gambrel Roof - Is Clear Span Posible? (36'x48')

Will there be a loft? If not then a Truss system could be constructed. If so then as long as you can get some 36 ft
beams then a Double keyed beam set up may work. 36ft is a huge span. I have seen this spanned once in a barn that had a tapered 12x27x36ft beam. It would be hard to find such a log for this today.
