The restoration of the large area of its grounds is designed to be in keeping with Sir Christopher Wren’s original vision for the site.
Carter developed the plans for the Royal Hospital’s South Terrace to once again ‘act as a plinth’ on which the Grade I listings buildings are set, opening up views of the 300-year-old heritage site.
The work involves redeveloping the South Terrace and an area of the gardens to allow the buildings to have clear and open views both to and from the banks of the River Thames, as Wren originally intended.
Unsympathetic landscaping during the 19th Century caused views of the Royal Hospital to be obstructed for several decades, and its redesign forms just one part of a renovation programme of the Royal Hospital’s estate that has included the refurbishment of the Long Wards housing the Chelsea Pensioners, which were completed in October 2015.
Titchmarsh said: "Having presented the Chelsea Flower Show for 30 years against the stunning backdrop of Sir Christopher Wren’s Royal Hospital, I am delighted and excited that the Hospital has had the vision to appoint award winning garden designer George Carter to restore the South Terrace.
"I can’t wait to see how fabulous it will be, opening up views of these magnificent buildings, set off by sweeping lawns with clipped pyramids of yew and a row of boxed lime trees peeking above a new yew hedge."
Paul Hatt, secretary and acting chief executive officer of the Royal Hospital, said: "We are very pleased with the support our application has received from many eminent UK conservation bodies and of course RBK&C planning and conservation officers and councillors and our most knowledgeable Commissioner on this topic, Alan Titchmarsh.
"We are required to protect and preserve the historic nature and fabric of the site, and we are convinced that this scheme will restore the setting of this important heritage site for future generations."
In addition to the landscaping alterations, the Royal Hospital will change the paths on the South Terrace to sealed gravel to ensure that all areas of the grounds are accessible to Chelsea Pensioners (including those using mobility scooters or wheelchairs).
Meanwhile, show garden designers for Chelsea 2015 now include Charlie Albone with Husqvarna and Sam Ovens who replaced the Rich Brothers at Cloudy Bay. Rosy Hardy will design for Brewin Dolphin.
Anne Marie Powell and Philip Johnson are designing show features.
Other designers involved include Andy Sturgeon, Cleve West, Hugo Bugg and Jo Thompson.
