Handmade Flint and Pebble Blocks
Easy and Cost Effective Flint Work
South Downs Flint, a Sussex based company makes the traditional labour intensive methods of creating flint walls, easier and more cost effective with flint blocks. We produce a concrete block with pieces of flint inserted, which can be laid as quickly as block walling, with only pointing required to ensure the finished construction looks completely authentic.
Materials are carefully selected to ensure the appearance of a traditional hand-laid finish. This means that a traditional building look can be achieved for new flint builds or to meet a conservational requirement.

We can match existing flint work, or recycle existing flint from old properties and walls and re-use these for new flint blocks.
