Design & Usability

With generous dimensions and a tall profile, the Isabella Annexe 250 Etna offers more than just storage — it functions as a fully usable extension of your awning. The integrated mesh windows provide excellent airflow, while external covers protect against the elements.

The addition of a second zip allows you to create a partition between the annexe and the main awning area, giving you flexibility to use the space as a private sleeping area or separate storage zone. The rear access door also means guests can enter and exit without disturbing the main living space.
