Hyalu B5 promotion trailer

2026with plainshape

For La Roche-Posay we turned the design for a Hyalu B5 promotional trailer into reality: from rendering to a road-ready sales space.

It all started with the client's visualisations: a shiny trailer that opens at the side, with steps, a bright sales area and Hyalu B5 graphics, set in the middle of a city square. Our job was to turn that image into a real, robust trailer.

  • Taken from the design: large side flap, fold-out steps, white shelving wall with blue-backed compartments, a screen in the centre and a free-standing counter
  • During the build: interior fit-out with shelving, counter and lighting, fitted precisely into the rounded aluminium shell
  • Result: the finished trailer matches the design down to the last detail, from the shelf layout to the graphics on the flap and counter

The gallery shows the finished trailer first, followed by the visualisations from the client's design and finally the interior fit-out during construction.
