We turned to the AD archives to see how the pros handle strange spaces (think tiny staircase landings and the gap above your kitchen cabinets). The space midway up your stairs is a great place to catch your breath, so why not make it even easier to do so with some seating? The elmwood comb-back Windsor chair dates to the 1780s, and the candlestick table is from the late 19th century; the carpet and runner are sisal.
