The image above shows good intention but very poor execution, and what can happen when a specialist is not consulted. They accidentally created a barrier.

This bathroom is at an upscale restaurant in Dallas. The rectangular shadow is a sink. The doorstop was put in to make sure people washing their hands weren’t hit by the door as it opened. The unintended effect was that the door no longer opened wide enough to allow a power wheelchair through. They have made their bathroom non-compliant to ADA Standards with this choice.
