LONDON — House of Fraser has created two new roles, naming Maria Hollis executive director of buying and design, and Dorothy Maxwell head of sustainability.

Hollis will manage the buying and design functions across the store, and will work with the teams on buying, design and sourcing. She will also concentrate on working with brand partnerships.

She joins the company from Asos where she was global product and training director. Hollis has held positions previously at Arcadia Group and Whistles.

She will report directly to Nigel Oddy, chief executive officer, and will begin her new position on May 9.

“This newly created role will bring together, for the first time, buying and design functions across the business, allowing a more unified and strategic approach to key trading areas of our business,” said Oddy.

“Maria’s expertise and guidance will be invaluable to us as we continue to work to enhance our leading multichannel proposition and to grow our business.”

The retailer has named Maxwell to the newly created position of head of sustainability. She will oversee the retailer’s corporate sustainability commitments.

Maxwell has worked with brands and retailers including Nike and John Smedley on environmental and sustainability initiatives. She has served as a special advisor to The Prince’s Charities, governments and NGOs.

She reports to Peter Gross, chief operations officer.

Executive chairman Frank Slevin said: “As we develop and position House of Fraser for the future both in the U.K. and internationally, we recognize that we must be at the forefront of the retail industry in key areas such as our approach to the environment and wider sustainability. With this new role within the company, we look forward to realizing our sustainability ambitions.”
