The blocks in this playhouse wall interlock on placement..
Watch this very brief demo and see how easy our interlocking blocks are to put together. Every component in system truly interlocks with every other component. Our blocks do not rely on gravity, glue, or mortar. Our blocks simply interlock upon placement. Once interlocked, our block will not shift up, down, left, right, or sideways. You can pick up projects assembled with our block and they will not come apart. Post assembly of block, optional reinforcements can be added to increase stability.
Basic blocks with sideways facing lugs.
There are two types of Basic Zipblock, those with lugs facing sideways like the ones shown in this picture and those with them facing straight down the length of block. Lugs are the mechanism, which mechanically interlock components together. Upon placing two blocks together, the lugs within the two components will interlock. Watch this movie and discover how the lugs function. Discover how lugs provide hollow passageways that can be used to pass optional reinforcements thru.

Basic blocks with forward facing lugs.
There are two types of basic Zipblock, those with lugs facing forward like the ones shown in this picture and those with them facing sideways. Lugs are the mechanism, which mechanically interlock components together. Upon placing two blocks together, the lugs within the two components will interlock. Watch this movie and discover how they work.
Different block sizes can interlock together.
Watch this movie and learn how different sizes of Zipblock interconnect. You'll be amazed at the simple and innovative methods used.
Enlarging blocks with forward facing lugs.
The red, white, and blue block illustrated above is an enlarging-block. Enlarging-blocks allow you to transition to larger blocks.
The enlarging block in this movie was made from several different colors so that as the layers are removed you can see how simple it is and how it functions.
Reduction-blocks also exist. They allow you to transition from larger to smaller size block.
Reduction and enlarging-blocks allow you to transition block sizes with ease.
