We already discussed that venues should have four principles in common. They should be easy to reach, access, use and understand. These principles are part of the so-called accessibility chain. They apply to the route to, route on and route around the venue in question. On the one hand, they encompass elements such as the building itself, parking space, path to the venue, hallways, the entrance area, the welcome desk or sanitary facilities. On the other hand, they also comprise information, communication, experience and assistance. The saying "a chain is only as strong as its weakest link" holds also true for the accessibility chain. To create a strong accessibility chain and to make a venue reachable, accessible, usable and understandable, it is important that all elements of a building fit together and that each team member is familiar with these issues. The first element "reach" means getting to the venue. This includes the use of public transport, accessible parking lots, level footpaths and the entrance. Basically, if you cannot get to the venue, you cannot experience a play or a concert. The second element "access" addresses the way through a building or venue. Once you have arrived at the location, you should be able to enter the building or venue and reach a certain destination, for example the welcome or ticketing desk, hallways, toilets or your seat in the auditorium. The third element "use" means the use of facilities at the venue. Imagine, you are standing in the entrance hall but you cannot reach the information desk or the clothes hook in a cloakroom. Your seat might be too small or you cannot hear the sound, use services or enter the café. These are obstacles that disable people. Finally, the fourth element "understand" means finding our way around and "understanding" our environment. For example, when we walk through a building, or our environment in general, we use colours on the floor, signs, text and icons as well as light to orientate ourselves and see where we have to go. Thus, "Understanding" is the last element of the accessibility chain. To sum up, "Good Design enables, bad design disables". This means that we have to remove the obstacles that might disable people. Moreover, we should bear in mind the context of the building or location when aiming at its accessibility. It is important to be aware of the accessibility chain for our environment: reach, access, use and understand.
