BUILDING PILLARS

PILLARS WITH TANDEM 90 AND 180 UNITS

Note that it is possible to build a pillar using a mix of 90 and 180 units, but no pattern has been defined .  

We recommend only using 90 mm structural units to build the inside of this type of pillar and by using  

the 180 mm Lafitt veneer units E and F .
