When interior designer Stephanie Dunning of Dunning & Everard was asked to work on all the interior architecture and design for two new floors at Hampshire vineyard Exton Park, the brief was pretty extensive. It included the creation of a dining room to seat 20, a bar for a chef’s dining table, a kitchen to cater for 50, a club room, boardroom, mezzanine bar and office. The great hall also had to be big on wow factor.
