There are several different branches of Quakers, as a result of various splits over the centuries, with different worship styles and somewhat different theology. The most evangelical branch (EFCI) often refer to their congregations as 'Friends Churches', and have buildings and service styles that aren't radically different from other protestant churches. At the other end of the scale there are also meetings which hold fast to traditional silent worship, some with a very liberal theological attitude and some (though fewer) with a conservative one. There are a lot fewer Quakers in this 'unprogrammed' tradition in the world, though, partly because the more evangelical and orthodox programmed meetings were quite active in missionary work. In Britain, FWIW, almost all of us follow the unprogrammed tradition (and would definitely refer to our building as a meeting house, or meet in a community centre or something - the building is not important in our theology). In the US less so, though unprogrammed worship is fairly strong in Pennsylvania and a few other places.
