I've make four cobblestone pillars lit up by torches surrounding the compound that Ross and I constructed. You should be able to find it if you follow the coast keeping the water to your left from the spawn. It's safe except from spiders, so you'll probably be fine if you're inside.
Also the main gate is a redstone circuit, I have a basic knowledge of redstone but it's probably not as efficient as it could be. If anyone can make it better feel free to tear it down and remake it.
Oh and help yourself to the communal meat locker.
