By the 60's, both H. Stanier & Co and New House Fashions had grown considerably. They had diversified too, as the companies manufactured knitwear and underwear for customers such as Marks & Spencer and British Home Stores too.

When Harold Stanier died in 1969, the two Companies combined under the New House Fashions name, and concentrated on the manufacture of knitted fabrics and textile machinery. By the 1980’s, the Company had also added roller blind fabrics to its portfolio. To reflect these changes, the company name was altered from New House Fashions to New House Textiles.
