Instant Green: A 180 m² Roll-Out Sedum Roof in Wiltshire

In April 2025, Wallbarn helped transform a garden outhouse in Ramsbury, Wiltshire, by installing a 180 m² roll-out sedum green roof. The homeowner, Ian Mills, chose a simple and effective green roofing solution that could blend naturally into the surroundings, support biodiversity, and require minimal upkeep. 

Project Overview

• Location: Ramsbury, Wiltshire 

• Date: April 2025 

• Project Size: 180 m² Wallbarn

• Installer / Client: Ian Mills Wallbarn

Why a Roll-Out Green Roof?

Ian wished for a green, living finish that would integrate seamlessly with his garden. The roll-out sedum system was chosen for its speed, simplicity, and natural appearance. The aim was a mature-looking green roof from day one, rather than a slow build-up over time. 

Installation & Performance

The roll-out sedum system is delivered pre-grown and installed across the roof surface. Because the trays are ready to go, the installation process is straightforward and fast — ideal for residential settings where disruption must be kept low. Wallbarn

Once in place, the green roof delivers several benefits:

• Enhances visual appeal and softens the building envelope

• Provides habitat for pollinators and local wildlife

• Helps manage rainwater runoff

• Offers long-term, low-maintenance performance Wallbarn

Conclusion

This Wiltshire project demonstrates the value of a roll-out sedum roof system for residential buildings. With minimal complexity in installation and maximum visual and ecological payoff, it’s a great example of how green roofs can elevate modest structures into garden-integrated assets — immediately and sustainably.
