Is there a small step in the indoor bedroom?

Hello, I don't think it's good, because it's inconvenient to get in and out of this step, and the wheelchair for the elderly is an obstacle. Professional decoration companies will level the balcony and living room too high, but pay attention to the outward slope to avoid rainwater entering the living room. Or you can stick a threshold and chamfer the corner of the balcony at 45. Especially those who have old people and children at home need to pay more attention to safety issues.
