Well as a pleasant surprise you are one of only a few who have decided to give me a name to address you in this channel. It shines a bit of light onto your request at least.
That being said, I am surprised to see a relatively small company such as Gateway attempting to undertake this task. From the coordinates, I think it more likely that you plan on building directly in the Niobium fields than at Stokes. Of course, all of Leeds is Her Majesty's but that field is under the administration of our nationalised corporation, Bretonia Mining and Metals, who will be working with Bowex for the most part. Restricting access to them hardly seems the best business procedure. A bit more detail on that, and exactly where you'd be acquiring Gallic commodities like Cryocubes would be required.
We do need to think of the Kingdom itself, especially in war-time and being on the front lines. However, if you can ascertain the permission of BMM- then construction can likely go ahead. Of course, that would include the initial fee for processing this, and then the full amount before being approved - for now, nothing of the sort will happen.
