Highfield Garden World in Gloucestershire is close to finalising plans for the next stage in its development.

The project is likely to include expanding the centre's catering capacity by almost 40% to around 500 covers. The current restaurant accounts for 27% of Highfield's £7.4 million turnover.

Chris Primett of Malcolm Scott Consultants, who helped to design  the centre’s £2.5m restaurant and retail development completed in 2014, is working with the independent to draw up the plans.

Tim Greenway, director of Highfield, said: “Our 2014 development has proved an unmitigated success for us. We've always got our sights set on what’s next for the business, and now is a good time for us to take the next big step and make the business not just bigger, but even better for our customers.”

Opened in 1992, Highfield welcomes around 15,000 customers a week. The founding Greenway family still owns the business and three generations work within it.

Including concessions, overall site turnover is £11 million.
