Over time, the way that churches worship has changed. Congregation have reordered and adapted their buildings to reflect this, usually a number of times over the centuries. These changes can often be seen in the architecture, blocked or new windows and doors, aisles and chapels added and altars, pulpits and fonts moved.
Most changes have involved bringing the priest and congregation closer together. This is reflected in the current projects like installing a nave altar or movable seating to enable services in the round.
If you are thinking of changing your space to reflect the way you want to worship then you should ensure you your whole congregation and your governing body. It is worth considering temporary changes, and working with what you have to test out some options and see how people react.
