The Dorema Horizon Air Annex is a practical and spacious add-on designed to increase the usable living space of your Dorema Horizon Air awning. Developed by Dorema, this annex is ideal for caravanners who want extra room without upgrading to a larger awning. It attaches seamlessly to the side of the Horizon Air awning, creating a versatile extension that can be used for sleeping, storage, changing, or keeping bulky equipment neatly out of the main living area.
Constructed from high-quality awning materials to match the main awning, the Dorema Horizon Air Annex maintains a consistent look while delivering reliable durability. It is designed specifically for air awning systems, meaning stability depends on correct inflation. As with all air awnings, regular monitoring is recommended, and occasional air top-ups may be required to maintain optimal shape and tension, particularly with changes in temperature.
Easy to attach and practical in use, the Dorema Horizon Air Annex offers a smart way to adapt your awning setup to suit longer stays, family trips, or touring holidays where extra flexibility and space make all the difference.
We know buying an awning online and getting the right fit can be a bit nerve-wracking.
That's why we've created our Perfect Fit Promise.
