A method is provided for manufacturing a panel that includes a substrate and a top layer provided on the substrate. The top layer may include a decor film and a transparent film. The decor film may be a printed synthetic material film chosen from the group consisting of a vinyl-based film, a polyethylene based film, a polyurethane based film, and a polypropylene film. A print may be situated on an upper side of the printed synthetic material film. The transparent film may be a thermoplastic synthetic material film the material of which is chosen from the group consisting of polyvinyl chloride, polyethylene, polyurethane, and polypropylene. The method may involve providing the decor film and the transparent film on the substrate by performing a first press treatment at an increased temperature to form a package of the substrate, the decor film, and the transparent film. The first press treatment may be performed by a calendar device or a continuous press device. A structure may be formed in the thermoplastic synthetic material that forms a surface of the package by performing a second press treatment using a press device with a structured press element at a temperature that is lower than the increased temperature.

In some embodiments, a building block includes alignment elements that interlink with a similar block with a positional offset. For example, the positional offset may be linear and/or rotational. For example, the second cinder block may be rotated with respect to the first block on which it is supports. Optionally, protrusions from the top of the block are positioned to interlink to the vertical slots at a fixed offset between the blocks. Optionally, the protrusions are formed by channels on a mold and/or a mold head. In some embodiments, a structure may be built stacked blocks. Optionally, a decorative face is configured to form a continuous decorated surface across offset blocks. In some embodiments a building block includes a calibration feature. For example, the block may include a ridge on the top of the block that may be shaved and/or ground to adjust the height of the block.
