Looked at the topographic map of the area, it appears there are some unbuilt warmish slopes (out of the image) a bit north (within 2,5-mile radius) of the intended new centre , but some of these are marked as a military area. Maybe the swedish military will step forward? Still the naturally warmest large location here is the current centre. Climate change will help... And anyway there is plenty of swamp to dry before people can enjoy a mosquito-free new centre.
The scale is pretty large, yes... my estimates:
some 10 miles of highway, 5 miles of railroad, at least about 50 miles of streets, some 7 miles of dredging to dry the 2,5 square miles of bogs nearby, 25 miles of fence for reindeer migration, new water plant from a different watershed, pipelines for pure water have to be dug over 5 feet deep in this climate...
