Dorema Onyx 270 Deluxe XL Annexe – Spacious Extension for the Onyx Awning
Effortless Expansion of Your Living Space
You can extend your Onyx 270 awning’s usable area with the Dorema Onyx 270 Deluxe XL Annexe. Designed to zip securely onto either side of your existing awning, this annexe gives ample room for storage, sleeping, or relaxation. It adds flexibility without altering your main awning. Whether you need extra gear space or a private retreat, this annexe makes it possible.
Generous Size & Practical Design
With a footprint of 250 × 150 cm, the Deluxe XL Annexe gives you sizeable space. It features a rear door, plus end windows for daylight and ventilation. The curved roof design complements the Onyx 270’s style, maintaining clean lines and effective water flow. You can attach it to the left, right, or both sides using Dorema’s double-zip system. Because of this versatility, you adapt your setup based on needs.
Materials & Compatibility
This annexe uses the same high-quality TenCate All-Season materials as the Onyx 270 awning. It shares durable coated polyester fabric, robust zippers, and strong framing to match weather performance. Also, the colour option (Charcoal / Grey) harmonises with your awning for a unified look. It fits Onyx 270 awnings and works with existing pole or steel frame sizes.
Comfort & Ventilation Features
You’ll appreciate the end windows which bring in natural light and fresh air. The rear door allows easy access and helps with airflow. Also, optional features like a curved roof help with drainage and reduce water pooling. Because the structure uses high-quality materials and thoughtful ventilation, it keeps the internal environment comfortable and dry—even during longer use.
