Gardens need structure. They also need structures, says AD100 landscape designer Madison Cox , “a reason to experience a garden as opposed to just walking through it.” Case in point is the never-before-published pavilion at his Marrakech home, Villa Oasis—the legendary house renovated by his late spouse, Pierre Bergé , and Yves Saint Laurent in the 1980s.

Eight years ago, Cox added an octagonal structure of painted cedar, with French doors, a marble table, and chairs for which artist Lawrence Mynott devised needlework upholstery. Executed by a charity for lepers, the fetching stitchery mixes Marrakech scenes and botanical studies, plus a monogram or two. Now the one spot of the garden, Cox says, that was “pretty much never seen” has become an enticing destination for l’art de vivre.
