The initial selection of clay product  &  creation of mock-ups to show product colors, textures, joint mortar finishes and sizes

CT001VB – Corso Terra Dragwire – Vintage Bianco

  • Corso Terra Dragwire – Vintage Bianco
  • Thickness of joint = 2cm (note that thickness of brick is 4cm)
  • Joint mortar flush both vertically and horizontally
  • Joint mortar color = tone on tone with bricks


This was a joint effort between the S.Anselmo Engineering Team, architects and designers in order to define Open Bonds Design. This design was to be a façade system that stood out 42cm from an existing back load bearing wall and took into account the following:

  • The local seismic regulations require the use of horizontal L-shaped anchoring to the back load bearing wall to support bricks for each story.
  • In order to create Open Bonds bricks must be interconnected with vertical steel rods and satisfy local seismic regulations
  • Steel rods would not be seen through the Open Bonds.

The design of open bonds is the result of careful analysis and comprehensive structural study on seismic requirements and impact of vertical and horizontal anchoring for the final look of the building.


The structural analysis combined with the design of the building created the final project which then had to be developed for bricks production.

  • 3 different lengths of bricks needed
    • 50, 36 and 22cm
  • 13 different types of bricks developed in order to create holes for vertical rods to go through
    • with 4, 3, 2 holes and without holes for the 50 and 36cm-long bricks
    • with 2 holes (in different positions) and without holes for the 22cm-long brick
  • Each brick produced with a specific code printed on the bed to identify the type


Given the complex design and the wide variety of brick types involved in the project, a “Brick Façade Construction Manual” was provided to local bricklayers. Every morning, each bricklayer was given a page with specific instructions describing which brick went where. S.Anselmo supervised in the initial phase of the installation.


The vertical rods were welded to the L-shaped horizontal supports. Each vertical rod was 1.5m long and they were threaded so they could be joined by a long bolt. Given the thick joint (2cm) compared to the thickness of the bricks (4cm) there was a limit on the number of courses that could be laid with fresh undried mortar. To help this process and to speed it up a neoprene spacer was used between bricks in order to support the weight. The first story was hung on L-shaped horizontal anchors of the second story such that by looking upwards from below no anchoring system would be seen.
