Description Change this

The new pavilion for the Hakone Open-Air Museum designed by Tezuka Architects is comprised of a structure entirely assembled with timber logs without any metal parts. Cutting-edge structural analysis has been employed to overcome the loads resistance variability that characterizes timber. The structure used traditional wood joints even though Tezuka Architects conceived a futuristic form.

The pavilion is located at the Hakone Open-Air Museum, a unique open museum located in one of the most visited tourist spots in Japan. Woods of Net was added to the collection of art works as part of their 40th anniversary.


This is a permanent pavilion for a net artist, Toshiko Horiuchi Macadam. The artist knitted the net entirely by hands, which is designed for children to crow in, roll around, and jump on the net. It cannot be exposed to rain or ultraviolet light. The objective was to design a space as soft as the forest where the boundary between outside and inside disappears. The space attracts people like campfire. The children play inside of the net just as fire and parents sit around and lay on the woods.

In the interior of the pavilion a series of nets create an artificial topography for children. Nets are configured at different levels to create platforms, resting and playground areas.


The structure is entirely composed of timbers without any metal parts. 320 cubic meter of timber members are used and there is nothing same among all the 589 members. The latest structural program was developed for the pavilion, but the joint techniques are derived from thousands years old Japanese wooden temples in Nara and Kyoto. As long as the proper maintenance is done, it is capable of existing over 300 years. This is the oldest and the latest structure in the world.

The pavilion was designed to be permanent and dismountable with 100% recyclable materials. Since its completion at the end of 2009, the pavilion has gained the recognition among critics for its unconventional use of traditional materials and responsibility towards the natural environment.

Come visit us at the Children’s Museum of Winston-Salem in NC and experience one of Toshiko Horiuchi Macadam’s masterpieces in the United States! It’s even more wonderful than we had hoped and working with Toshiko and her husband, Charles, was truly a joy and an honor. Hope to see you on the net!
