Totally. I can't imagine what wood elves would do without wood. Dear me, how will they build?
I'm thinking bosmer work as teams, chewing a native leaf, until it has the property of cement. Then they spit the cement out and pack it into the form of their dwelling.
They can't chew leaves as it would violate the Green Pact. One assumes they could use wasps or other insects that chew leaves for this purpose, however.
So add insect nests to the chitinous remains of giant insects, trees (as in Falinesti and others) bones of giant animals, coral, seashells, stone, metal, amber (as in Silvenar), giant oak-apples, underground tunnels, etc etc
I have a fairly detailed version of Valenwood culture/law/religion/etc in my head and hard drive (because my brain has dork problems), and in it I have their society dominated largely by sort of corporations/socal clubs/political parties called lodges. I didn't realize until now how similar they were to the idea of a cyberpunk megacorp as mentioned above. I note this because I had one of the major lodges as the Spinner Lodge (every lodge has a totem, usually animal). The Spinners train and ride giant spiders which puts them in high demand. Spider silk, if you're not aware, is stronger and more flexible than steel. It can also be woven onto a tree without damaging it, which is why I imagine it as the backbone of all Bosmer tree-based cities.
