Every child deserves a chance to a better life!


UNHabitat estimates that 1 Billion people live in slums and informal settlements today. This number will double over the next 8 years, requiring 75 000 houses to be added EVERY DAY to house just the new inhabitants and not taking into account upgrading living conditions for current inhabitants. No conventional building methods can achieve this goal.

Looking at what was offered as possible options today, it soon became clear that most designs and products only addressed some of the most basic requirements with little or no attention given to the more important aspects to turn these low-cost temporary ideas into real livable long term solutions. Most designs and ideas focus on the two critical elements, cost and mobility with little or no regard for any more than keeping the rain of the inhabitants backs. Items most often overlooked are safety and security as well as one of the most crucial elements to curb the spread of diseases and provide the most basic resource to sustain life, access to  and storage of clean water.

Born and raised in Africa, Hein had the unique opportunity to experience first-hand the real needs and requirements of people in third world countries. Upon seeing a young girl outside a dilapidated shack on a cold and smokey morning, he realized that her options were severely limited by the environment she was born into and that she will most likely never achieve the possible greatness she might have been capable of. She could have been the doctor that found the cure to cancer or the first human to set foot on Mars, but her skills and talents will be wasted by having to spend hours upon hours collecting drinking water for her family and carving out a meager existence in a cruel and unforgiving world. Instead of having the opportunity to study and excel, she will be doomed to a life of survival and uncertainty.

He witnessed the daily struggle to keep families safe and secure in these low incomes, remote and sometimes war ravaged communities. It ignited a drive and a desire to find a practical workable solution to one of the biggest humanitarian crisis's facing the world today.

Makazi’s Sand Puzzle House incorporates features to address critical items like:

Ease of construction. 
      Parts are manufactured and panels assembled in a controlled environment and shipped to the erections site.
      Due to the simplicity of the design, panels can be constructed extremely fast and efficiently. It is estimated that 20 workers will        be able to assembly components for more than 1000 houses per month, making this building method ideal for supplying in the          ever-growing demand.

• Fire Safety
        Most informal settlements consist of structures built out of flammable materials like plastic and wood.
        Most the structures are built in close proximity to each other with limited access and escape possibilities.
        No fire fighting resources are available and access to fire fighting equipment is usually non-existent.
       Open flame is the still most common means for cooking, heat and light and every year, thousands are killed in fire related 
• Security & bullet/shrapnel resistance
        Our panels have been subjected to the most common ammunition's like AK47, 9mm and .45 Caliber projectiles with no 
         penetration recorded. In high crime areas or locations that has recently seen armed conflict, this is important to ensure safety
        and protection from stray fire and shrapnel. 

No infrastructure, tools or skilled labor required
         Experience has taught us that anything of value like hardware and tools, WILL disappear from job sites because of their resale 
         So our next challenge was to design a way of connecting all panels without the use of tools or hardware.
         As a result, no infrastructure like access to electricity or water is needed for erection of the structure.
        Panels are secured using dovetails which also eliminates localized stress points in the structure, therefore making it extremely          suitable for application in heavy seismic areas.
        No skilled labor is needed and simple instructions will provide enough information for assembly by locals, creating jobs in the
        process. Items are color coded to make assembly a breeze and instructions understandable to the most unskilled person.
Use of local and/or recycled materials.
       Once all walls have been erected, local inorganic materials can be used as filler materials to secure the panels. 
       This filler material will also render the panels fire and bullet resistant and act as insulation.
        Internal components will be extruded from recycled materials and will be recyclable, making the structure environmentally                friendly.

Ease of transportation and erection.
       Panels are small and lightweight enough to be handled my hand without the use of lifting equipment.
       Several houses can be packed and shipped in a single shipping container for deployment.
       Erection of a single room structure by 3 unskilled laborers can be done in less than 3 hours.

Ease of expansion and changing configurations
      Due the the unique design for installing and securing panels, adding onto an existing structure will be quick and easy.
      Different configurations allow for several different applications to include but not limited to: 
                 Clinics and hospitals
                 Offices and Businesses
                 Recreational and Off-Grid housing in remote areas.
                 and many more.

We are looking to raise funds to have the production line set up, extrusion dies made for internal components and the first batch of demo units manufactured and erected.
