Super! Pour info, d'après les régulations une rampe pour fauteuil doit être inclinée à max 1:12,5, et 1:16 en extérieur non couvert. La hauteur de "marche" maximum est de 20mm.
Of course! Your work is fine! In any case, official régulations make for very long ramps which are always a very big hassle to fit in an existing project. However they are calculated so that the wheelchair driver can climb them without assistance. Resting stages even have to be arranged if the ramp is too long. I understand it, when you are disabled, independance is most precious. But in the end, every attempt to help handicaped people is always a most welcome initiative, and your helping hand is a very beautiful act of kindness!!

Magnifique! Une leçon d'architecture! Bravo!
