Hi All,

I am after some advice. I have a transportable holiday house which has a trussed roof over bathooms and bedrooms and cathedral ceiling over living area, kitchen and dining area. The ceiling has exposed beams. As per the attahced sketchup models i want to raise an existing opening closer to the peak of the cathedral ceiling and open it up by a little shy of 5 meters. the central wall (which incidentally runs from one end of the house to the other and supports trusses in th back half of the house) is a little over 200mm thick and it would appear (from visible timber in the roof) that the house is constructed of 70 x 45 framing. The house is supported on besser blocks and tied down with one row of stumps immediately under the central wall.

I'm not too bad on the tools having built a few pergolas, decks and renovated a couple of houses but not sure I'm up to this one. I understand that cathedral ceillings are often self supporting but not sure if mine would be or not.

I was thinking a decent LVL placed high in the wall woud be the go but I'm after any advice regarding feasibility of this project including how you would go about it and what materials you would use.

I will endeavour to post real pictures shortly

Thanks in advance
