Anybody built one recently. I have tried to source an existing one but no luck (I need slightly bigger than T hangar

). Rand's new expamsion plan is for T hangars so does not suit. Seems it FASI, FABB or Panorama for me. FABB is doooooozie and am told FASI space running out fast, but seems building is only option for da toy box. Have some quotes, but prices vary significantly (<R500/m2 to over R1000/m2). Anybody used GP based crew or if you are in the game drop me a line.
Obviously any comments and/or contacts appreciated. Erected within next 6 months providing I can source a site. Also need some help with the layouts to accomodate all the crap that one has collected over the years... looking at 21x14x5.5, or there abouts.
