We purchased a kitset shed a few years ago and have only just got around to arranging to get it setup. We submitted an application for building consent with the council. It was a large shed, so needed building consent. However the council have declined the application because they said the shed and the structural calculations for it, are for a low wind zone property and the property is in a high wind zone. They want me to get an engineer out to the site to test the wind speed and submit site specific calculations for the shed. However the kitset shed was sold to us as being suitable for a high wind zone, and it was one of the first things we checked with them, as we know it is a windy area. The company we purchased it from says they have never had any problem with other councils, but say if our council needs these calculations to be done, we will need to pay for it from a engineer, which will probably be at least $500 and take over a month to do. I had planned to assemble  this over the xmas break, and had submitted my consent to council quite a long time ago, not expecting this sort of problem. We have been discussing this with them over the last few weeks. Do people think we should have to pay for this extra engineering calculations to be done, considering they sold it to us as being suitable for a very windy property? If it was sold as suitable for a high wind zone property, would it have been reasonable to expect that the structural calcualtions for it would be for a high wind zone too? Building consent by itself cost over $500, which is more than I paid for the house one 10 years ago.
