I found the design is double-storey and height 5m.(H)
So this year we’re launched a regulation for health friendly and safety policy. that it cause for this year we’re allowed maximum height 4m. (must be set back from side is closed to neighboring stand) and back wall – side wall not over 3.5m.
Double storey, is only permissible for stand covering at least 60 sqm. and the upper storey can only cover up to 50% of its area. (30 sqm.)
