Are there any building materials considered non-vegan, especially in the context of constructing apartment buildings?

1Well, there's a patent for the "Use of blood in the cement, mortar and concrete industry for obtaining a lightened material". Above that, it is conceivable that there is non-vegan insulation, paint, glue...– celluCommented Apr 20, 2017 at 18:50

I believe wooden beams used to be painted in ox blood for fire protection. Animal glue, wouldn't be used these days anymore, except maybe for a historic restauration.– TurionCommented Apr 20, 2017 at 20:03

Rammed Earth may be non-vegan as it has traditionally used blood as a binding material.
But now we come to a thorny question for vegans. Since concrete is made from cement which is made from limestone which often comes from caves where bats lose their home, will you use concrete? Animals may have suffered in its production.

2It's not thorny if you don't require vegans do go further down the rabbit hole than anyone else. Commented Apr 22, 2017 at 12:25
