Isabella Coast 250 Annexe incl. Frame

Add to wishlist

• Adds a proper extra room to your awning – The Coast 250 gives you a fully enclosed extension that can be used for storage, sleeping or even a separate living space.

• Tall design makes it genuinely usable – Unlike smaller annexes, this has full standing height, so you’re not crouching when getting changed or moving around.

• Breathable acrylic walls improve comfort – The Isacryl fabric allows airflow while still protecting from weather, helping reduce condensation inside.

• Flexible frame options for touring or seasonal use – Choose lightweight CarbonX for easier touring or stronger Zinox steel for longer stays and stability.

• Can be divided into two spaces – The built-in zip allows your awning side panel to act as a partition wall, which is useful for privacy or separating storage from sleeping space.

• Frame options:

  • CarbonX fibreglass (lighter)

  • Zinox steel (stronger)

• Weight (approx.):

  • CarbonX: 14.5 kg

  • Zinox: 19.2 kg

• Colour: Ocean

• Includes zip system for internal partition use

• Optional extra: Inner tent

If you’re deciding between using this as storage or sleeping space, it’s worth factoring in the optional inner tent — it transforms the annex into a proper bedroom. For touring, the CarbonX frame makes life much easier when packing and pitching. If you’re seasonal or pitching for longer periods, the Zinox steel frame is the better choice for strength and stability.

If you’re unsure how this (annexe) will fit, especially combined with other gear, don’t guess. Give us a quick call on 01452 730100 and we’ll help you check your van’s layout against the awning’s rail height and depth. We’d rather you get it right first time.
