I can see the logic of the potential move, and am quite relaxed about them taking on Adelaide Cottage.
> No material public money has been spent on doing the property up just now. I understand a major upgradation of the property took place in 2015, as part of an ongoing proposal to upgrade and renew the building.
> It will allow W&C to be much closer to HM in the last days of her reign. The benefit of that cannot be understated. Not only will there be a lot for them to learn, it will help bring their office much closer and better integrated with the BP / Windsor machinery.
> If such a move happens, they will, in essence, end up with 2 homes (Adelaide Cottage and KP 1A) that are taxpayer funded. Anmer is privately owned. Whilst AC can be their main home for the next few years, they will need a place in London as they will often be in London for work, a lot of which will not be in the public gaze. Further, their offices will remain at KP, which means there will be a lot of back and forth to KP.
> I do not think AC is a long term home for them. It has been suggested that in the next reign, W&C will move to Windsor Castle. C&C will divide their time between CH/ BP (once the decade long renovations of BP are complete) and Highgrove, and will perhaps only have a nominal presence at Windsor. To me, this makes sense, given Charles' love for Highgrove. At that stage, AC will revert to being the grace and favour home it has been for royal staff.
> KP 1A has already been used by W&C since 2013 (9 years now), barring the period 2015-2017 where they spent a lot more time at Anmer while William worked there for the Air Ambulance Service. Also, in the next reign, KP 1A will continue to be the London home for the Cambridge family. I suspect their next move in London, when the time comes, will be from KP to BP. All of this will mean that W&C will have gotten a fair amount of use of KP 1A since its 2013 renovation.
