Nicely done and theoretically a good location - possibly only local location, lovely touch with the New 3d stand
There has to be considerations regards use, a single use stadium alone cannot make enough money with one team playing in it, it has to offer much more, conference/catering/education facilities, possibly even an attached hotel (that can be part of the conference/catering facilities) plus other shops including retail store for the club.
A 4g training ground (including gym) that can be used for academy games with a small stand possibly attached to the main stadium - so changing rooms all located in one area and run out to the training pitch direct from the main stadia.
To accommodate that the car park behind should be removed completely, with no through road to the residential area. There should be a huge discouragement to drive to the stadium excepting for those with a blue badge, encouragement to cycle/walk, use public transport, possibly putting on 'rugby' buses that go from the outer estate areas and back again, was it the no.73 that went from Bransholme - Sutton Park - Orchard Park - West Hull? maybe even possibly a train halt as there is already the rail line that runs back of Arco
Having that many cars come through a residential area is not a good thing and not really acceptable these days, there's enough of an issue with the huge fair ground and the disturbance it causes local residents now never mind localised pollution, alternates to private vehicle travel for games would have to be looked at and should be for where we are now.
If we ever have the chance of a new stadium, I'd be wanting to have 20,000 as a minimum, this means more likely to get internationals and other potential sporting events. I'm also not overly fond of the rectangular box stadium that is like the Halliwell Jones, I know they are cheaper to build than something like our current home but it makes the stadium IMO less appealing and exposes more to the weather for the fans, something similar to the KCom WITHOUT the upper tier in West, maybe variable standing/seating 'rail seats' in the centre of the 'cop' ends?
That's not a criticism of your efforts, they're great, just personal opinion of what I'd like to see if some extremely wealthy backer came in for us.
Small points regards the actual design, it looks like the Hessle road end stand is significantly further back from the pitch than the others and the front concourses could/ maybe be a bit narrower so that the seating is closer to the action. Though I love a nice deep in goal area it looks to be 10 metres, making it a few metres less could bring the fans a bit closer still and still have the run off area which is actually better than we have at the moment.
Also wonder if the stadium would fit with long sides East to West?
