The Acadian Orogeny
Cumbria’s landscape has always told a story — not in words, but through the materials that lie beneath its surface. Cumbrian slate, formed over 450 million years ago, is a product of ancient volcanic activity. Layers of fine ash and debris, deposited by eruptions during the Devonian period, were folded under immense pressure during the Acadian Orogeny (circa 450–420 million years ago). The result is a durable, fine-grained stone that has shaped the region’s built environment for generations.
From raw material to contemporary mosaic art
Today, this same material plays a very different role — as the foundation for contemporary stone mosaic work by Maggy Howarth Studios. Founded by the late Maggy Howarth and now led by her son George, the studio has become known for its incredibly intricate pebble mosaics, which appear in public spaces, private gardens, and civic projects across the UK. The work reflects a strong connection to place, both through the use of local materials and through designs that often reference natural and folkloric forms.

Where geology meets design
The connection between geology and design is central to the studio’s work. Where natural processes created the material — slate, sandstone, and pebble — the studio applies human skill to shape and arrange it. The randomness of geological formation meets the precision of hand-laid composition. What begins as raw stone becomes the wing of a dragon, the legs of a stork, the swirl of a fish, or a geometric spiral set seamlessly into a public plaza.
Why Cumbrian slate excels in mosaic work
Cumbrian slate lends itself especially well to this type of work. Its fine grain, structural integrity, and rich colour range — from Kirkby blue-grey to Westmorland green — provide both functional performance and aesthetic versatility. It’s no accident that these mosaics remain as durable as they are beautiful: they are built to withstand decades of weather and footfall, making them ideal for high-traffic landscapes and architectural schemes.
A studio evolving under George Howarth
Under the joint leadership of Mark Currie and George Howarth, Maggy Howarth Studios continues to evolve. While maintaining the distinctive style pioneered by his mother, George has expanded the design vocabulary with new motifs and techniques, always responding to the particular needs of site-specific commissions. Whether working with heritage restoration teams, local authorities, or private garden designers, the studio balances creative expression with practical application.
A fusion of natural processes and human craftsmanship
The result is work that quietly integrates into its setting while elevating it. Each mosaic carries with it the memory of its materials – its geological history, made by fire, water and extreme pressure, through compression, folding and the building of mountains – and the hand of the artist who set each stone. It’s a rare fusion of natural process and human creativity, offering both visual interest and long-term value in the built environment.

Connecting design to landscape and place
For designers, architects and clients seeking truly distinctive artworks using the finest hand crafted materials, Maggy Howarth Studios continues to push creative boundaries and build on the legacy of its Founder.
