What happend to the home- Builder and the do it yourself contruction of Your own home? Due to higher demands in the regulations is it today in the western world almost impossible for an amatuer home- Builder to set up their own home. Insulation value, fire risk, energy documentation and so forth has removed the possibility for the home- Builder to save Money and do it themself.

EggCube tries to give a sollution to this challange. By seeing the building as a Product based upon several bigger parts you can create yourself (or buy from a producer) you can put togheter Your own dream home to a lower cost, and still fulfill the regulatory demands.

By presenting a test project, within the spirit of open Source, will you here be guided through a process you yourself can reproduce. You can also choose to get manufacturer to produce the parts for you, and manage the process to get Your own house.

After finishing my master thesis "the EggCube Project" from the scool of Engineering & Architecture at Aalborg University in Denmark, I started my Professional career at one of Norways biggest module producers. There I soon realized the concept driven in this part of the construction business. While architects and engineers traditionally make their business by selling their knowledge, the module and housing container industry is solely focused on selling their end Product, "the module".

All the drawing I made as an architect/engineer, while beeing an emplyee at Hedalm was given free of charge to potensial customers. Incredible ammount of time might have been spent, even if there at the end was no sale made. Sometimes even compediting producers might have been given the order, based upon the drawings I made.

The module and housing container industry has unformally followed the code and principle of open Source and creative commons. This is done with free development of drawings, made by producers to their customers in the process of creating a sale og the module/ container product.

This drawings has then naturally been shared with other customers, and recivers of these drawings has used one producers drawings as fundation to get a product produced at a competing factory for a lower cost. This unwritten agreement among module and housing containar to not compete on imaterial rights, and instead compete purly on the basis of price and possibility to deliver the final physical product follows indirectrly the norm established among todays open Source producers for the "internet of Things".

To create a community for architects, engineers, students, contractors and others with a common interest to collect and share knowledge about modules and container buildings for an improved industrial building process.

With a constant growing world population is it in all our interest to realize a sollution where everyone can have an acceptable living standard.

Open Source Housing and Buildings by using the sharing model from open Source and Creative Commons on the digital data about houses and building

- Modular building process CC/GPL
- Large scale 3D printing
- Data driven Production CNC etc


While the internet of Things is developing in a rapid speed, will the Construction business be affected by it? Some 3D printers can in theory print concrete in large scale. Imagine a huge Construction crane Connected With cables to the putsmeister pump and the concrete- truck, printing the concrete and slowly building up the bearing structure of your building.

The day this printing Crane exist, this will remove some of the steps in the creation of the baring structure of a building, but it will not revolutionize the whole building process. To do this many small steps must be improved, for every material and every layer that creates a building. With a higher ammount of automatisation, robots and smart machines, this can replace man Labour, but will only be implemented if it is more cost efficient. To follow up to this, it is nessesary to ask the question: is really the answer for future Construction business to create an impoved factory line on site, and what is then the difference from todays methods?

- Low cost Production With manual Labour or Automatic machines and robots, anywhere in the world, transported and delivered on the bulding site for Assembly. Quality Control, will the parts fit, etc

- Standarisaton

This is why the revolution given by internet of Things is not changing the Construction business the way People seem to hope. The problem or challange is scale and the multitude of different materials needed.

While small Products in size will be manufactured anywhere in the future, will the bigger Production of Construction follow the more established system of Contractors With Production on site, or With half- finished elements and parts (such as modules), all suited to fit the transport on roads. This means that anything that fits on a truck can and will be produced by anyone With the meens to start a modern 3D Production facility.

For Objects larger than what would normally fit on a truck, will Assembly on site be necessary. This includes many of the known elements already known on Construction sites, With Cranes and big machinery to handle the parts.

EggCube belive the revolution for the Construction business first will come With a smarter planning With short way to Production of the parts needed. Easy to assemble and easy instruction to where the parts are going. Managment the building process like how a kid would build lego kit following its instructions.

and a university Project i uk shows how a 3D printer can "weld/print" steel in a larger structure. Moving a 3D printer to site will in many ways just be the same as is done today With on site Production. Man labour is drastically cut, but the idea with creation and value- making on site stay the same.

Step by step:

1.1 Frame

 Standard Steel frame following the standard ISO size and joints for containers
- Special Steel frame With sizes outside the ISO system, but With the same joints

- Alternatively can you use an shipping container (high cube model) as the starting point. This might be a cheeper option, if you do most of the work yoursel. It will furthermore demnad more steel work like cutting and welding compared with an ISO frame made for housing / building purpose
