         10 . A method for applying a veneer exterior wall, comprising:
 building a sheathing layer, wherein a lower edge of the sheathing layer is formed on a top surface of a foundation and an upper edge of the sheeting layer contacts a ceiling structure;   attaching a first multi-purpose screed device along the lower edge of the sheathing layer, wherein the first multi-purpose screed device comprises:
 a wall cladding section; 
 a plaster support section connected to the wall cladding section at a first edge, wherein a plurality of first openings and a plurality of second openings are formed through the plaster support section, the plurality of first openings are closer to the first edge than the plurality of second openings, and the plaster support section is substantially planar; and 
   an end ventilation section connected to the plaster support section at a second edge, wherein a plurality of third openings are formed through the end ventilation section;   attaching a weather-resist barrier (WBR) layer over the sheathing layer and the wall cladding section of the first multi-purpose screed device layer;   attaching a rain screen layer over the WBR layer, wherein the rain screen layer aligns with the plurality of first openings in the first multi-purpose screed device; and   applying a veneer layer over the rain screen layer, wherein an exterior surface of the veneer layer aligns with the third edge of the first multi-purpose screed device.   
     
     
         11 . The method of  claim 10 , wherein attaching the first multi-purpose screed device along the lower edge of the sheathing layer comprises:
 securing the wall cladding section of the first multi-purpose screed device to an exterior surface of the sheathing layer, wherein the first edge of the first multi-purpose screed device is positioned below the top surface of the foundation layer.   
     
     
         12 . The method of  claim 11 , wherein the WRB layer terminates at a distance above the first edge of the first multi-purpose screed device, and the rain screen layer extends to the first edge of the first multi-purpose screed device. 
     
     
         13 . The method of  claim 12 , wherein the veneer layer is a stucco layer and a portion of stucco layer through the plurality of second openings. 
     
     
         14 . The method of  claim 10 , further comprising attaching a second multi-purpose screed device along the upper edge of the sheath, wherein the first and second multi-purpose screed devices are identical, wherein the WRB layer covers a portion of the wall cladding section of the second multi-purpose screed device, and the rain screen extends to the first end of the second multi-purpose screed device. 
     
     
         15 . The method of  claim 14 , wherein attaching the second multi-purpose screed device comprising securing the wall cladding section of the second multi-purpose screed device to the exterior surface of the sheathing layer, wherein the end ventilation section of the second multi-purpose screed device faces the ceiling structure. 
     
     
         16 . The method of  claim 15 , further comprising inserting a cover structure in a gap between the end ventilation section of the second multi-purpose screed device faces the ceiling structure.
