In autumn 2020, Wiking Gulve received an inquiry from designer Peter Mortensen and architect Jeppe Ecklon about a completely new, special design for wooden floors. The contact was established through membership of The Upcycl – a forum that identifies residual materials with circular potential for incorporation into other products/designs.

Peter and Jeppe's vision was, in addition to creating beautiful solutions, to design, develop and market high-end and climate-responsive products precisely to meet the demand for sustainable products of high and consistent quality. At the first meeting at the factory in Roslev, the designers brought drawings for a wooden floor in a previously unseen format, shaped like a rhombus. A rhombus is a parallelogram characterized by all four sides having the same length, the two opposite lengths being parallel, and opposite angles being equal. As Wiking Gulve is known for producing and marketing wide and long plank floors, this new design had to be thoroughly considered in terms of materials and production methods. Initially, 30 pieces of oak were cut so that the visual expression could be assessed, and then it was decided to initiate a small test production where the materials used in the product would only consist of surplus wood/residual materials in the form of short cut-offs from longer lamellas.

The Rhombus Parquet was thus brought to life, and Peter and Jeppe have since founded Whynature to market what is hopefully the first product in a long line of new sustainable designs from the two visionary gentlemen. The Rhombus Parquet is now in full production at Wiking Gulve and is a new and elegant design classic in a significantly different format, while existing residual materials from Wiking Gulve are utilized and upcycled. In other words, Wiking Gulve's usual quality wood is further utilized by giving residual material a new life and thus contributing to solving the climate challenge.

Even very short surplus pieces can be used for Rhombus Parquet, which not only contributes positively to significantly higher resource utilization, but since production takes place very close to the usual production of plank floors and does not need to be transported further, the climate footprint is significantly reduced. Rhombus Parquet, marketed by Whynature, is made from Danish oak with a core of pine from the North Swedish forests, naturally using green electricity and is included in Wiking Gulve's Cradle-to-Cradle certification. The product clearly distinguishes itself from other rectangular wooden floors, and the special geometry of the Rhombus Parquet fully exploits the differences in width to length, which creates a highly distinctive visual effect that varies with daylight, shadows, and the season. The Rhombus Parquet has a 3-layer construction, like Wiking Gulve's other products, which ensures further dimensional stability, and can be laid floating or fully glued to the subfloor.
