Beautifully simple and elegant, the square hole design has been used for centuries from castles, keeps and manor houses to modern extensions and art galleries. Indeed many of the grilles we make are for a wonderful array of clients and their properties including the delightful Wiltons Music hall in London and shop fronts along the stunning period high street in Chester, England. We even ship these made to measure grilles out, supplying the architectural practice, Tendenze design in New Jersey USA with a substantial order of bespoke grilles, a property owner in Florence, Italy with just one grille and even a pair of grates all the way to a house in Auckland, New Zealand!
