We're looking at replacing the 3-ply 2x12 beam with LVLs to eliminate the post.

That was just a quick iPad sketch by my builder to get the idea across to me. Definitely not a construction drawing.

Unfortunately getting rid of the post is not so easy if I retain the beam. The beam is two sections of three 2x12's laminated together. The mid-span of the beam rests on the post, with the ends resting on studs in the walls. Yes, trusses would solve the problem but I'm interested in reusing as...

The post is actually useful because I use it to run power down to the middle of the shop. The beam is a complete pain in the @ss however.

Uh, why?

After talking with my contractor we've stepped away from the pre-built truss idea. Preliminary plan is to re-use the existing roof joists as the bottom chord, raise the beam so that the top of it is level with the top of the joists and then stick frame in the rafters with collar ties. Currently...

The interior height will be 3 feet high by eight feet wide x 23 feet long according to the drawings supply the truss manufacturer. Granted that’s not walking around height but it’s a a heck of a lot more storage than I have now which is absolutely zero. I’m not a truss designer so I leave that...

That’s possible I suppose but has a couple of disadvantages. I wouldn’t gain any storage space in the attic nor would I be able to remove the interior beam that runs the length of the building. It would also add visual height to an already thick roof assembly.

Totally agree with the limited space in a 5/12 pitch. The challenge I have is that if I go higher then I will run into the overhead power service into the house. Moving the electrical service would require much more work and expense as it would have to run to the garage first, then to the house...

Got a quote from a local truss company for 5/12 pitch trusses with attic space. Total of 13 trusses, 2x6 construction with 2x4 webs. Delivered with tax: $3552

Yes, the beam is lower then the joists by the width of a 2x12. The joists sit on top of them beam. And you raise an excellent point that I had not considered. The joists are not connected to each other where they meet. The ends overlap but they are only connected to the ridge beam. This raises...

Thanks, appreciate the photo.

Interesting approach. Do you have pictures of the final result?

Some loft storage would be ideal!

That’s a good point actually. I was operating from the perspective of reusing as much of the existing structure as possible. The centre beam is a major pain in the neck to be honest.

I have a 19'x23' double garage with a 2x68 framed flat roof. There is zero insulation in the ceiling so it's brutal in the summer. I live on Southern Vancouver Island so the winter is not too cold. I'd like to add a peaked roof with the 2x6's as the bottom chord of the rafter. The garage has a...

I'd just use regular concrete. With care and attention paid to leveling the forms and screeding it should be plenty good for a greenhouse.

Thanks so much I like that those pubs have sound transmission ratings.

Wow, that's a fantastic resource. Thank you!

Thanks, this is an interesting idea. I've seen it done for walls but not for ceilings/floors. I'll mention it to my contractor.
