Constructing a staircase using the Catalan vaulting technique, which uses fast-setting mortar and thin bricks to create a self-sustaining structure

I'm an enginer ph.d and inspector and this works because of the angle which is why it's wider at the top. The downward pressure supports the structure force toward the outer wall.

Catalan vault:

Note: The Catalan vaulting technique, developed by Antoni Gaudí, uses thin, self-supporting brick layers to create curved, stable structures. This method reduces the need for scaffolding and formwork, making it both cost-effective and innovative. It's ideal for creating arches and vaults in buildings, offering both aesthetic appeal and structural efficiency.

This is why Third World countries look the way they do after an earthquake

@reygodo Una tècnica de molt antiga història perviveix tot i que els espanyols no l'han volgut acceptar com a element resistent i útil a la construcció, al no incloure-la al Codi Tècnic de la Edificació, CTE, demostrant la ignorància i odi que tenen amb tot el que sigui català. Seguim.

Use carefully 😜

Amazing architectural creativity wow the flexible stairs

My pea brain is trying to envision why this is working. Im guessing due to the curving the bricks are pinching themselves together. Its for sure interesting.

Amazing skills.

I'm afraid it will collapse halfway through construction
