Yesterday I replaced my personal debian archive at https://www.littletux.net/debian (which used a simple, flat structure) with a pool based archive. The archive is handled by debpool, a debian archive management tool which is quite simple to set up. It is available from the Debian experimental archive. The main advantages from this tool are that I can use the standard dupload tool to upload packages to the archive, and that it allows to manage packages for various distributions like stable and unstable. To access the archive, it is sufficient to add lines like deb https://littletux.homelinux.net/debian unstable main contrib non-free deb-src https://littletux.homelinux.net/debian unstable main contrib non-free to /etc/apt/sources.list. Note that www.littletux.net does not work.
