Transforming a Studio Roof in Just One Day with Wallbarn’s M-Tray® Modular Green Roof System

When London-based designer Charlie Barker wanted to soften the look of his newly built studio, he was searching for a simple and sustainable way to hide the exposed black waterproofing and bring life to the space. Measuring just 10m², the flat roof was the perfect size for Wallbarn’s M-Tray® modular green roof system — a quick, low-maintenance solution that can completely transform a small roof area in a single day.

A Quick and Effortless Transformation

Charlie wanted something that looked professional but didn’t require a specialist team or extensive maintenance. Wallbarn’s M-Tray® modular green roof system ticked every box. Each pre-grown sedum tray arrives ready to install, meaning there’s no need for tools, soil handling, or planting.

Within just one day, Charlie was able to self-install the entire system, instantly transforming his studio roof from a dull, functional surface into a vibrant, living garden.

The Benefits of the M-Tray® System

The M-Tray® system is designed for speed, sustainability, and simplicity. Each tray locks neatly into place, creating a seamless and fully established green roof that starts benefiting the environment from day one. It’s an ideal choice for smaller projects or urban homes where access can be limited, as every component is lightweight and easy to handle.

In addition to improving the visual appeal, the new roof also brings clear environmental advantages:

• Encouraging local biodiversity by providing habitat for pollinators such as bees and butterflies

• Helping to manage rainwater runoff and reducing pressure on local drainage systems

• Offering a natural layer of insulation, supporting more stable internal temperatures year-round

A Studio Garden That Inspires

The finished result is a modern, natural-looking studio roof that adds charm to the garden space while reflecting Charlie’s creative style. The lush sedum planting changes colour with the seasons, adding year-round interest without the need for regular upkeep.

Charlie was so pleased with the outcome that he created a short video showcasing his installation and the final look — a perfect example of how quickly and easily M-Tray® can elevate even the smallest of spaces.

Greening Urban Spaces One Roof at a Time

This project highlights how Wallbarn’s M-Tray® modular green roof system makes sustainable design achievable for everyone — not just large commercial developments. With its straightforward installation, long-term durability, and instant visual impact, M-Tray® is proving to be the go-to solution for homeowners and designers looking to create greener, more beautiful spaces in cities across the UK.
