Construction of an arch-shaped hall 12x30x6m

I am selling a steel structure of an arch-shaped hall 12 x 30 m. Height 6m. The steel structure is clad in aluminum. Inside there is lighting, 2x doors. For the less understanding — the land is NOT part of the sale and no, I will not sell it. Only a demountable arch hall. The hall will be dismantled, ready for transport.
