Architects Directory Alumni: MacKay-Lyons Sweetapple The Wallpaper* Architects Directory has turned 20. Conceived in 2000 as our index of emerging architectural talent, this annual listing of promising practices, has, over the years, spanned styles and continents; while always championing the best and most exciting young studios and showcasing inspiring work with an emphasis on the residential realm. To mark the occasion, in the next months, we will be looking back at some of our over-500 alumni, to catch up about life and work since their participation and exclusively launch some of their latest completions. One of the first Wallpaper* Architects Directory alumni, featured in 2002, Brian MacKay-Lyons gives us a tour of his firm's latest residential project, Mountainside, a ski retreat on the slopes of Utah.
