If you wanted to do a bit of research, you will see that the current/new event offers a new Event Building, and that Kits are made available for the more recent Event Buildings (for that particular event, not other events). Looking at the Beta, the 1 year old Event Building is offered 3 times as a daily - and although Beta Daily are not the same order as our current server, the rewards are very much similar (not necessarily identical, but very close) - and in fact, recent Events have the year ago Event Building kit available on Day 1, as well as once or twice again during the Event. So odds are that next Winter Event, the Bakery Kit will be available 1-3 times.
If you are worried about wasting space, I would suggest using a Store Building Kit, and put the incomplete bakery back into your inventory until such time you can max it out - although, by the time Kits are available to max it out - you may have discovered newer buildings that are better than Bakeries, and you will not want to have any bakeries taking up space anymore.
