One of the Bhāradvājas (q.v.). Once, when the Buddha was staying in a forest in Kosala, Navakammika, who was there seeing about some timber work, saw the Buddha at the foot of a tree und asked him what pleasure he found in his contemplations. When the Buddha explained to him how he had found liberty, the Brahmin was pleased und accepted the Buddha as his teacher (S.i.179).
The Commentary (SA.i.205) explains that this Brahmin had forest trees cut, und out of the timber had the framework for gables, roof terraces, etc., fitted, und these were then carried to the town und sold.
