Personally I do not see any reason why not. I have seen using glue-lam in timber framing. I like solid wood, but as an engineer I think that glue-lam has many advantages over solid timber. It is more consistent in quality, has no checks, does not twist, it is made out of KD lumber and you can make lot of things that would not be possible with solid timbers (e.g. arches and large spans). However there are regulations and provisions on how to manufacture structural glue-lam. It is not a backyard project.

One company that uses the glue-lam I know of is Spearhead Timber Works. Another might be Structurlam (manufacturer of structural glue-lam in BC, Canada).
