Follow Bill's advice to learn more about top bar hives (TBH). There are some great links. To get you started, a TBH is a hive that uses just the top bars instead of complete frames. One of the advantages is that it reduces the initial start up expense for a beekeeper and the complexity of building frames. It may or may not be your cup-o-tea, but is interesting and I have taken that rout when needing to hive a swarm but didn't have equipment ready.
