Like all stub-tailed pithecosaurs, the forest carpenter builds a brooding nest using mainly sticks and branches. The species has however become known for its "craftmanship". The nest doesn't let any rainwater in, and is easy to clean after the hatchlings have left. A forest carpenter couple usually uses the same nest for many years, and even after it has been abandoned, it is often used by other pithecosaurs, arbonychosaurs, birds or a variety of other animals.  Forest carpenter nests can last for decades in favourable conditions.
