I am finishing wrapping a building now.
Has been a nightmare the twp. came in and shut me down.
We were prepared but got held up in court for almost a year.
It is kinda crazy..they said I we were making the whole building a sign..
But basically the building existed and is metal. It sits off a main road behind another building.
We were giving it a new fresh look but added some details to create and overall going green feel.
and I had to defend the fact of people paint buildings crazy colors all the time. Well maybe not in some towns..but here there are...
Also I kept the type on panels where the names were before.
It all comes down to you can only cover a building with a certain percentage/sqft of type. Once I broke it down and showed them that I was close to there %..and with lawyers doing everything in there power.
We actually ended up creating our own varience..since they could not figure out what to do.
It was long road but we got somewhere and its approved.
Just make sure you get the approvals..I have seen a ton in magazines seems like most of them are temporary ..
As far as building files...I just broke it down into sections..files get HUGE fast. or you better have a mean machine.
Good Luck!!
