Yeah ...that's a local Somchai up top..flip flops and no goggles for welding..had the guy who finally finished the house "adjust" some of Somchai's angles..lol and add some more steel'
The guy who tiled the roof was a local rubber cutter... charged me 130k including soffits gables and bird screens ( I purchased all materials). I got some local kids to repaint the steel after construction 5k.? Good job too no leaks ........he said..
The steel frame was built by a worker of one of my runaway builders so don't know what it would cost..guess another 100k? ( runaway bought steel also)
Living area under roof is only 11m x 5m, roof over hang is 2m all round..don't know pitch so the math is back to you mate..5555 Finishing builder forgot to give my plans back otherwise you could have had 'em.
