sacred spaces in your homes

I am wondering, besides altars, does anyone do anything in their home to have it more conducive for a spiritual life? And how many here keep a permanent altar somewhere in their home? What room, etc? I am doing a little research on this and I am curious if this is something that people consider when setting up a home or decorating.
I am starting a small company this year which I will actually be calling Sacred Spaces.
My Mission is : To assist people in living soulful, spiritually nourishing lives by changing the attitudes around home and space as defined by modern design. I seek to integrate such practices as feng shui and mood therapy through colour into peoples homes and thereby creating an environment of peaceful living. As well I intend to provide people with sacred spaces such as reading corners, meditation rooms and multi denominational altars as a way of bringing stillness into chaotic lives.
So, I guess I am looking for some feedback, please.
