The Wikkelhouse was designed and built by a small Company in Amsterdam that started up as a theatre scenery Company in 1989.
Looking at it from the side, it is evident that this is a modular building. The 1.2m wide sections are clearly visible as no attempt was made to hide the separation line between the modules.
The Wikkelhouse comes in visible segments, with no shame whatsoever.
The interior is as good as it gets. Smooth plywood sheets wrap around the entire building envelope and give the house a unique look that feels premium and solid.
Even from the inside, the separation lines between the modules are clearly visible and this adds depth to the interior space. In theory, there is no limit to the number of modules (segments) you can add.
On top of the exceptional look and unlimited expandability, the clever Dutch people at Fiction Factory came up with a specialized module for the bathroom and one with the round window, plus accessories for kitchen, living room and stove.
This allows putting together a personalized version of the Wikkelhouse.
This modular concept is super simple and yet truly remarkable.
The entire house is installed on a chassis made of concrete blocks and wooden beams. The house is very lightweight (more on that in a moment) and, thanks to this particular characteristic, the chassis can be placed on leveled and compacted ground, requiring no foundations.
This cuts down installation costs and installation time.
Now, the truly remarkable innovation here is another one:
This house is made of cardboard!
Believe it or not, each segment is built by "rolling" a tiny sheet of cardboard over a steel framework.
The Manufacturer declares a wall U-value of approximately 0.29 W/m2K (R = 3.5).
U-value of windows is declared as 0.24 W/m2K (R = 4.2).
The 1.2m wide cardboard sheet is wrapped around the framework while 60 lines of glue are "drawn" on the sheet. The glue sticks the layers together and bonds the entire structure as a solid block. Once the glue has hardened, the steel framework is removed and the segment is ready for finishing.
Since Wikkelhouse is a modular concept the price is based on the configuration of segments needed. You can purchase a Wikkelhouse from EUR 30.000,- (based on 3 segments and excluding transport and placement).
