Making of The Simplest Concrete Spiral Staircase 

Stunning. What a beautiful piece of work in both design and manufacturer.

Thank you for sharing this video. The strair is a masterpiece.

As an architecture student I loved watching this! The design is just mesmerizing and super interesting!

Felicitaciones, excelente resultado 👏

Congratulations. A This is a most stunning staircase of beautiful simplicity that honours very clever geometry. Thank you for creating such a fantastic film of the brave creation process. Very inspiring .

Like it because of beauty and accuracy

ultimate sophistication

Thank you so much for the sharing. I really love the construction techniques and details achieved by this housing project.

Beautiful design.. So elegant . I wanted to know how the tensile forces were taken care of without steel! and from the dimensions , i understood it is similar to a sunshade or loft slab!..can this concept be applied to such small cantilevers. Thank you.

looks cool, but no rebar? please explain the internal structure of the staircase.

めっちゃくちゃ幻想的です・・・住みたい・・・

This is very cool. I think the process of making the styrofoam forms would be equally impressive.

Nice design...!!... But it's a pitty that you didn't design a way to reuse the mold.. Even you could do a smaller mold with few steps, poor the concrete, let it set then lift it, again and again till the right level...

Great work, perfect precision! Two questions though: 1. What kind of mortar is this? How can it support the charges without reinforcement? Especially at the edges? 2. How come it is so perfectly casted even at the bottom? I see that it was all casted from the top. No vibrating?

I NEED TO MODEL THIS STRUCTURE FOR A DELIVERY, WHERE CAN I ACCESS THE DWG FILE OF THIS STRUCTURE?

Great design and visual simplicity but probably out of the budget of a DIYer like myself using the construction method shown. However a similar effect might be achieved via the ferrocement technique that uses a form that is reused to create identical riser sections. Each could be attached to the hidden base using threaded rod and the optional underside finished later or omitted. Ferrocement enables one to think outside the box, for example creating tiles for a heavily skewed patio space where no corners are 90%. The trick is to abandon rectangular or square tiles entirely and custom fit large format tiles to the existing shape. If you are faking large format ceramic tiles why not fake a $24 per square foot carrara marble finish as well. That's what I also do in a ferrocement version of this staircase.

Will you be selling the spiral stair blue prints? Can you feature how the concrete walls are built in Japan??

Wooow

Is it possible to get something like this in the states... for a reasonable cost?
