What's the best thing to build in minecraft PE town?

I'm making this town for me and my friends on my iphone and I need something that is awesome but doable in survival. No pools. Already have that

Try to make a wizards tower. I'm not saying a castle but just a tower sorta in the shape of just a circle spiring up and have those mini towers come off the sides. Also insied the tower in the middle you could have lava pouring town and water pouring down also but with spires wrasping around it like in this video

but never forget detail. Its so important cuz if you just have a plain square/circle itll look bad (if you need to know how to make a minecraft circle just type "minecraft circles" on google images) this will take some time but itll look great when your done also just think what every town needs eg.
barracks
town hall
church
a king tower!
i could go on forever. I hpoe this helped and have fun!

  • What are some tips for a few people trying to build something big in minecraft? How would I plan it out is my biggest problem. Are there any apps for iphone or programs where I can make some blueprints? I'm playing minecraft on Xbox so world edit isn't an option
  • Nanny cam or some way to watch my place while out of town? I go out of town frequently and have someone watch my house and pets. Sometimes I think they just skip days and don't even do what I'm paying them to do on some days. Do you know of any good cameras that I can since to my iPhone or computer, so I can watch my place while I'm out of town? A friend recommended a nanny cam, but I just want to make sure I get a good one and an affordable one at that. Any suggestions/recommendations would be much appreciated, thanks.
  • Is there a town that's stuck in the 50's? I'm looking for a town that is 100% time warped. Like, where they only play black & white censored movies & television, none of today's technology is used (iphones, microwaves, laptops, etc), and the girls wear dresses and there are no string bikinis, and all the people in the town act the way people did in the 50's. I really just want to jump back in time… So does any of you know of a place in the US or England like this?
