Natural Spanish slate contributes to revival of 19th Century architectural spectacle, Heworth House.

In keeping with Victorian Gothic architecture, Cupa Pizarras' CUPA R12 Excellence slate was selected by Brierley Groom Architects for the striking redevelopment of Heworth House in York.

The 19th Century rectory was originally constructed in 1865, expertly envisioned by the York-based architect, George Fowler Jones. Over the years, Heworth House has had several changes of use, including a day nursery, offices and a health clinic. However, it is now being converted back into a residence, featuring six premium apartments.

Although the Victorian Gothic rectory isn’t a listed building, it does sit within the Heworth conservation area, which is designed to protect the special architectural or historic interest of the buildings.

This obligation to preserve the unique and distinctive environment Heworth House is surrounded by was central to the brief. Brierley Groom Architects’ sympathetic design optimises the use of the existing building, without having a detrimental impact on the build or historical environment.

Cupa Pizarras’ natural slate has been the go-to material choice of architect, Matthew Groom for his projects since visiting the Cupa Pizarras quarry in the North West of Spain: “We consulted with the team at Cupa Pizarras who provided us with samples of a suitable slate. It was important to respect the character of the building, and with CUPA R12 Excellence, we were able to achieve this.”

A high-quality dark grey slate with a smooth surface, CUPA R12 Excellence helps to maintain the building’s original architecture.

With a guaranteed lifespan of more than one hundred years and minimal maintenance, the slate provides a smooth, uniform and visually stunning finish that will last. CUPA R12 has also been approved for use in Eryri, Snowdonia National Park - tested and approved as an equal to local Welsh slate in terms of its characteristics.

In addition to its durability, natural slate is considered a sustainable choice for roofs, as it goes through a simple production process that requires no chemicals and less water and energy than alternative roofing products. This approach to manufacture has resulted in CUPA 12 gaining BRE Global Certification.
