Production begins at the starting point defined during the preparation phase. The first raw slab is selected according to its size, shape, surface and intended position within the project. It is moved into place using vacuum lifting equipment and positioned within the full-scale outline marked on the production floor. The first stone establishes the starting point for the stones that follow

Each stone is individually shaped using traditional slate shears. The craftsman reads the natural structure of the slate and determines where and how the stone should be cut. The edge is shaped gradually, preserving the natural character of the material while adapting it to the surrounding stones. This is skilled manual work. No two stones are identical, and every adjustment is based on the stone itself and its position within the complete surface.

After the first stone has been positioned, the next stone is selected and shaped to fit it. The third stone is adapted to the first two, and the process continues across the full surface. Each new stone becomes part of a growing composition. The craftsmen continuously consider the size and shape of the stones, the direction of the joints and the balance between larger and smaller pieces. The aim is not to repeat a fixed pattern, but to create a coherent surface that makes the best possible use of the natural slate.

Quality is assessed continuously as the surface is created. Each individual stone must work together with the stones around it, but it must also contribute to the overall composition. Forms, proportions, joint widths and joint directions are reviewed throughout production. Reference lines and measurement points are used to ensure that the surface remains consistent with the production drawing. Adjustments are made while the stones are still laid out and accessible.

When the final stone is in place, the complete surface is reviewed before numbering begins. The project is checked against the production drawing, reference lines and full-scale markings on the floor. The craftsmen then step back and assess the overall composition. Any stone or detail that does not contribute to the intended result can still be adjusted at this stage.

After final approval, every stone is given a unique number.

The numbering follows the planned production, installation and packing sequence. Arrows are added where necessary to identify outer edges or the correct orientation of individual stones.

Alignment marks are drawn across neighbouring stones. These marks help the installer position the stones correctly and reconstruct the original joint pattern on site.

The stone numbering is connected to the project drawing. Reference numbers are added at corners, section boundaries and other important positions. This creates a clear link between the completed production layout, the packing sequence and the installation drawing. The documentation allows the installer to identify the correct starting point, locate each section and understand how the numbered stones relate to the complete project.

The complete surface has been created at full scale. Every stone has been individually selected, shaped and fitted.
Forms, joints, lines and the overall composition have been reviewed. Each stone has been numbered and marked, and the project drawing has been updated with the necessary references. The project is now ready to be packed in the correct sequence for transport.
