Is it possible to change city size in SimCity

An abandoned building will eventually be reacquired if its problems are resolved. You can see why the building was abandoned by clicking on it to bring up information that building.

In many instances this will be a reason like the building having no water or power, there not being enough jobs within commute distance, pollution or backed up sewage, or the building being damaged by fire.

Abandoned buildings will have a negative effect on the land value of nearby buildings, and have an increased chance of catching fire. Keeping abandoned buildings around over the long term will drive down land value for the surrounding area and it is usually recommended that once the building goes 'dark' (visibly darker than the surrounding buildings - like the one in your screenshot) that it has begun to decay and will soon reach a point that it is better to bulldoze that building to prevent it from causing damage to the value of the surrounding buildings.

When you activate the bulldozer tool, all abandoned buildings of any zone type will begin flashing with an orange symbol with a line through it to make them easier to locate.

Changing locale/language in Origin and reinstalling SimCity at least gave me the option to select installation language. I know it's not quite what OP was looking for, but I did get rid of the horrible Swedish translations, for what it's worth.
