I think that for most people, a nice icon corner should suffice.
It's not the glamour or ostentatious aspect that is important for spiritual growth.
In fact, it might actually be a bit vain to try to "out-church" the next guy.
I once read that a layperson visited a monastery and wished to have an audience with an elder. When he was allowed admittance to the monks cell, he had expected something wondrous, gold gleaming icons, twinkling in candlelight, etc. What he found besides the mat for sleeping, was a paper icon, pinned to his wall, and the candle was oil with a wick, burning in an old soup can.
It's not outward piety that is important...it's what is in the heart and soul.
However, if OP, liftsifter, is planning on using it as a church for the neighborhood, this is a whole other matter. Many churches have begun in someone's basement or garage, and grown into large parishes over time.
Either way, I hope that liftsifter is able to accomplish what he needs.
