The shop area is 25 per cent bigger, with new flooring, more tills, and a new Customer Information Desk.
The Café Bar has also increased in size by 30 per cent, with a new food hall area, more seating, plus a new menu.
Low energy LED lighting has been installed throughout, and this will roll out to all other Squire’s Garden Centres later in the year.
The plant area has a new and improved layout.
Deputy chairman Sarah Squire said: "We are absolutely thrilled with all the changes at our Long Ditton centre. It is so much bigger now which means that we are able to offer our customers much more choice, in a very stylish shopping environment."
