Category Information

At Howarth Timber & Building Supplies, we offer a wide range of Decorative Aggregates products, including Scottish Cobbles.

What are Cobbles?

Traditionally, Cobbles have been renowned for forming the main feature of cobblestone roads and walls. Whilst still used to build roads, Scottish Cobbles are now a more commonplace feature in gardens, particularly around ponds and creating focal points.

Our range includes Scottish Cobbles that are 50-80mm in size which is a popular size to use for ponds and in rock gardens. We also have Black and White Cobble that are 40-90mm in size. They are available in standard bag sizes which is suitable for basic applications including small rockeries. 

Scottish Cobbles are a round stone with a smooth surface and come in a variety of pale and subtle tones of colour.


Our range of products is of a high-quality and supplied by some of the UK’s leading suppliers.
