There are plenty of examples mentioned here:
Religious humanism - Wikipedia, the free encyclopedia
The earlest example I know of is this:
Cult of Reason - Wikipedia, the free encyclopedia
Note also August Comte's
religion of humanity, which has this temple in Brazil.
And I believe this chapel as well:
Why wouldn't they? It's a place to assemble and carry out any meetings, sermons, ceremonies, or aesthetic appreciation specific to their values and worldview. A temple doesn't have to involve the worship of a deity.
Note the following Wikipedia information about Comte's Religion of Humanity:
The Religion of humanity was described by Thomas Huxley as "Catholicism minus Christianity".[2] In addition to a holy trinity of Humanity, the Earth and Destiny, it had a priesthood. Priests were required to be married, because of the ennobling influence of womanhood. They would conduct services, including Positivist prayer, which was "a solemn out-pouring, whether in private or in public, of men's nobler feelings, inspiring them with larger and more comprehensive thoughts." The purpose of the religion was to increase altruism, so that believers acted always in the best interests of humanity as a whole. The priests would be international ambasadors of altruism, teaching, arbitrating in industrial and political disputes, and directing public opinion. They should be scholars, physicians, poets and artists. Indeed all the arts, including dancing and singing should be practiced by them, like bards in ancient societies.
My views are quite a bit different than Comte's, but I personally would love to see temples built to philosophical ideals, which actually makes me closer to a religious humanist than a secular one.
(Although my ethical views are perhaps a little unusual for humanists, so I don't normally call myself any kind of humanist.)
I personally would not consider someone's residence a temple, although a room set aside in someone's home could be a chapel.
