# Pine Plywood Spiral Staircases EeStairs Collaborates with Julia Van Beuningen By Kalin Ned | Published 2026-05-11 | Eco Source: Trend Hunter, https://www.trendhunter.com/trends/pine-plywood References: [eestairs](https://www.eestairs.com/blog/the-ahof-the-renovation-of-a-heritage-barn-in-holland/) EeStairs collaborated with interior architect Julia van Beuningen to design and fabricate a self-supporting [spiral staircase](https://www.trendhunter.com/trends/cobalt-coach-house) made entirely from pine plywood. This structure was part of the renovation of [Ahof Farm](https://www.trendhunter.com/trends/julia-van-beuningen), a listed 19th-century barn in Nijkerk, Netherlands. It is said to transform the agricultural structure into a modern, positive-energy residence. The pine plywood staircase features a helical form with no central support column. The design boasts crisp plywood edges, and a balustrade integrated into the treads. It serves to create a bold design statement within a space that otherwise relies on traditional materials such as lime plaster, flax, thatch, and exposed timber beams.
