I love, love, love breeze blocks! They act as a separating wall while still allowing the light in. These hollow cement blocks, sometimes called ventilation blocks, have been commonly used as essential building materials for the load-bearing walls of structures since the 1930’s. It wasn’t until the 50’s and 60’s that they became more decorative and used most often as ornamental screens. Using the breeze blocks indoors adds an interesting architectural element and using them in the garden adds an updated cool vibe.
