Stevensons of Norwich

What Stevensons of Norwich does

Stevensons of Norwich is a specialist decorative plasterwork manufacturer and installer founded in 1982, headquartered in Norwich, United Kingdom. The company designs, manufactures, restores, and installs finely detailed fibrous plaster, GRG (glass-reinforced gypsum), lime/lath plaster, and a proprietary Jesmonite-based material called Stevensons-Stone® used as a lightweight alternative to natural stone. Its portfolio spans standard catalog products (cornices, ceiling roses, columns, arches, fire surrounds, panel mouldings) sold through an e-commerce storefront, and a National Trust licensed sub-brand offering 48 cornice profiles reproduced from 15 heritage properties. The firm also delivers bespoke design, manufacture, and installation for heritage restoration, theatres, churches, public buildings, and high-end private residences, alongside ABTT-certified plaster surveys and reports for public buildings.

Revenue is generated through four primary streams: standard catalog product sales (unit pricing typically £41-£420 per item), quote-based bespoke plasterwork projects (multi-year contracts for complex installations), worldwide delivery and installation services spanning 40+ countries, and surveying/certification professional services. The go-to-market combines direct-to-consumer e-commerce (with free Click & Collect from the Norwich showroom) for standard products, and enterprise field sales targeting heritage property owners, architects, and specifiers for bespoke projects. Pricing is unit-based for catalog items and quote-based for bespoke work, with no disclosed subscription or recurring revenue component.

The company serves five primary customer segments: heritage properties (listed buildings, National Trust sites), theatres/hotels/public buildings, high-end private residences, churches and historic religious buildings, and Stevensons-Stone® projects requiring lightweight stone alternatives. Its enterprise customer base includes Theatre Royal Drury Lane, Royal Exchange Theatre, Queen Mary University of London, Royal College of Music, Stoke Rochford Hall, Goring Hotel, and international private residences in the Middle East, Hong Kong, and Mustique. The business is privately held with no disclosed parent company, funding rounds, or external investment, operating as an independent craft firm with 11-50 employees.
