Unreinforced masonry dressed stone#
General description#
Dressed stone GEM taxonomy: MUR+STDRE/LWAL+DNO/H1:5 Description: Unreinforced masonry buildings usually have solid irregular or tailored bricks made of limestone and granite, and in most cases with lime-sand mortar irregular bed joints. Although dry-joined masonry walls can also be found, these represent a small portion of the building stock and are frequently associated with monuments or cultural heritage. The most common type of foundation consists of a wider extension of the masonry walls in the soil, usually constructed with poorer quality materials. The roofs are usually composed of a wooden structure covered by clay tiles.
