It's interesting how each chapel develops differently, with different priorities, based on the resources/talents/background of the coordinator and/or group. You can tell what the coordinator and/or main organizers have to "bring to the table" by looking at each chapel.
This is obviously a carpenter's chapel :) Nice credence table, podium, pews, and altar -- all with the same wood stain.
Our chapel, on the other hand, was more heavy on the choir. We have 2 Liber Usualis, 2 Traditional Roman Hymnals, an electronic organ, a binder full of Catholic music, and the nucleus of a choir/schola. When Fr. Pfeiffer came in August 2013, we had a sung Mass. Materials wise, we didn't have much back then.
Also, I notice some chapels are nicer, better decorated, with large statues, etc. even though the room could only hold 20 people. The full-time employed city dweller's chapel? Our chapel, on the other hand, is pretty basic, although it is quite large (1000 sq feet). The part time employed homesteader's chapel?
And it's even more complicated in our case, because we also have a large contingent of young children. They take up space, but don't provide any resources -- so the group like ours can't have a high "dollar per square foot" density. It actually prevents quite a challenge, from a chapel manager's point of view. Imagine a game SimCoordinator, where you run a virtual chapel. One of the ways to make the game more challenging would be to add more children to the congregation. They wouldn't provide extra revenue, but you'd have to build more pews, provide more restroom facilities, etc.
Then there's that chapel in Ireland (see the recent pictures in the Resistance subforum) -- the "successful entrepreneur's chapel"? or a large group? -- I'd like to hear the story of how they developed.
Anyhow, I think it's interesting how no two chapels are alike, nor do they even develop in the same way.
