At the behest of The Prince of Wales, the artist Felix Kelly created an artist's impression of a remodeled Highgrove with neo-classical additions. Kelly had previously painted a vision of Henbury Hall in Henbury, Cheshire based on Andrea Palladio's Villa Rotonda. Kelly's artwork had formed the basis for the construction of Henbury Hall, and a similar painting of Highgrove subsequently formed the basis for a remodelling of the house in December 1987, undertaken by architect Peter Falconer. The remodeling saw the exterior embellished with a new balustrade, pediment, and classical pilasters. A new single-storey staff annexe was also added. The additions were praised by the Georgian Group.
