Lazarian Insulated Concrete Forms e(ICFs) are interlocking blocks produced from either expanded polystyrene (EPS) or expanded polyurethane (EPU).
Lazarian Insulated Concrete Forms (ICFs) are blocks made of expanded polystyrene (EPS) or expanded polyurethane (EPU) that interlock for construction purposes.
Lazarian World Homes has targeted projects on all continents.

Goal 11: Sustainable cities and communities
Small communities looking to build small public infrastructure projects, such as schools and community centers.
Lazarian World Homes brings the machine, chemicals, and molds to the site that are necessary to produce the polyurethane blocks. The cement and gravel for the concrete and the rebar are obtained locally and brought to the site.
Individuals and organizations can reach out to Lazarian World Homes with a project proposal. Lazarian World Homes works as a product manufacturer, installing contractor, and donor/fundraising organization. Their services come together and cannot be obtained separately.
104 projects have been completed and 3 are in progress.

The assembling of walls requires four styrofoam pieces, which include the Standard and Lintel Block, a Plug, and the End Cap. The Standard Wall Block and Lintel/Header Block comprise the main pieces. These blocks are 121.9 x 30.5 x 20.3 cm3 and weigh about 1.4 kg. The blocks interlock for assembly. It uses 3/8 rebar and concrete into holes/studs every 40.6 cm on-center throughout the wall and the same is done through the lintel block every 120 cm from the ground to structurally tie the building vertically and horizontally.
Lazarian World Homes has the building designs available for download.
Lazarian World Homes does not provide ongoing technical support. The user would need to contact a general building contractor.
Since Lazarian World Homes builds homes and does not sell the blocks as a separate product, a user would likely have to obtain additional blocks from elsewhere.
Lazarian World Homes projects an economic life of 40-50 years. They also suggest that the blocks can be recycled by grinding up the foam and mixing it into gardens for easier watering, or mixing as an additive into concrete blocks.
Lazarian World Homes claims that their homes are durable, affordable, and eco-friendly (because they are high insulating).
Workers are subject to the general dangers of a construction site that include working from heights and with machinery and sharp tools. EPS and EPU are combustible and therefore many codes require a thermal barrier such as drywall or plaster as a finish on the ICF.
