As with any building, Difra’s process starts with the architectural design. Difra, however, offers architects complete freedom of design, which allows for increased design complexity and personalization.

The architectural plans must be converted to 3D models, easily done with pre-existing software.

Difra’s proprietary software converts the digital 3-D structure into 2-D components, which fit together to form the framing of the home. Difra’s software automates an otherwise time consuming process, allowing Difra homes to be constructed faster than traditionally-built homes. Also, Difra’s software optimizes the amount of each piece of lumber used, reducing the overall material consumption and waste. Overall, Difra’s process requires 1/8th the framing materials of a typical construction site, by volume.

Once the 2-D components are generated, they are sent to a factory of computer-controlled laser cutters. These cutters mill the physical components from environmentally-friendly engineered lumber. The use of laser cutting creates precise cuts allowing for secure friction joints, which eliminate the need for nails during frame construction. Also, the computer-controlled lasers lessen the human error in the construction process.

Once the 2D-component pieces are milled, they are automatically labeled and packed with assembly instructions. Then, they are shipped to the construction site, allowing the possibility of Difra projects throughout the world.

On-site construction is efficient because the 2-D component pieces interlock via friction joints. This essentially turns the construction process into a large-scale 3D puzzle, where the precision-cut components are fit together according to a pre-determined construction plan. The assembly construction can be carried out in a fraction of the time required by traditional construction methods.
Difra is able to offer year-round union jobs on-site for supervision and assembly positions. Opening a global, year round, opportunity for union grade positions will be a boon for the construction trades in Massachusetts.
