Beautiful bricks hand-made by HG Matthews in the Chiltern Hills. They are ideal for both restoration work and new-build. Available in different colours and sizes. Contact The Old House Store for more details. Cob blocks are also available that are comparable with the conventional alternatives. Environmentally friendly in every respect, and excellent for extensions to existing cob and other buildings, as well as for sustainable new-builds. They can be jointed with lime mortar, covered in lime render and finished with lime wash.
