A twiggy home.

Why this works

The riddle "A twiggy home" cleverly plays with the idea of what materials are commonly used to build a specific type of home. The word "twiggy" suggests something made from small branches or twigs, which directly leads us to think of a "nest," as birds often use twigs to construct their nests. Thus, the answer works because it combines the imagery of twigs with the concept of a home, creating a vivid picture of a nest in nature.
