This building, which is located at 11 rue du Lion-Ferré, is known as the Chancellerie du Présidial, a name it acquired late in its history. Built in the second half of the 16th century, it consists of a single corps, de plan massé, giving onto a small courtyard. The framework seems to be all from the same period, and is numbered from south to north in Roman numerals. Dendrochronology allows us to date the wood to 1566. It uses the principle of assembly frameworks as set out by Philibert De l'Orme in his Nouvelles inventions pour bien bâtir à petits frais, which appeared for the first time in 1561. This involves laying the various wooden pieces out in situ and assembling them into curved rafters, which are held together by pegged crown plates. According to De l'Orme, these individual frameworks consisting of short pieces of wood allow the carpenter to bypass the problem of finding sufficient quantities of longer sections of wood. These assembly frameworks, also known as "Philibert De l'Orme frameworks" were only mildly successful in the 16th and 17th centuries, no doubt because carpenters were reluctant to have a foreign technique forced upon them, and Philibert's theories faded from view. On the other hand, the process was much more successful in the 19th century, after it had been discovered and circulated via Colonel Emy's Traité de l'art de charpenterie, which was published in Liège between 1841 and 1847. assembly frameworks allowed carpenters to cover particularly large spaces.
