What is BlockBuild?

BlockBuild is a masonry block construction system, not a cladding system. 


The one block makes up the entire wall of a house - no timber, gib, batts, or weatherboard. 


There’s no additional insulation, either - the ONE wall does it all. 


It is then rendered with lime-based plaster for an amazing finish, and to create a serene indoor environment. 

The end result is a home that delivers an unparalleled quality of indoor comfort & wellbeing on multiple fronts  - quietness, air freshness, temperature regulation, and humidity regulation.
