How to get the shiny towers?

I have some problem too, If you find any solution please contact me.

First, make sure you don't have any "frowny faces" anywhere...you must have full police, fire and health coverage in all of your residential properties.  Second, add some of the extended services to your city. I did Transportation first. You need to buy the "Department of Transportation" first and then use KEYS to add a bus terminal, etc... to your city.  You will find that the areas with these extra services have a higher property value.

Add the Education Department and then the schools, library, colleges too...your SIMS need an education.  The more educated SIMS use less water, produce less waste, fewer traffic jams and crime. The more "services" you have the higher the property value. You can view the land value by pressing the residential icon and then choose the other icons below it. The darker the blue and orange, the higher the value.

I built up my city with the brick buildings and "bulldozed" them one at a time when the land value was high - replacing them with new residential buildings...they became the glass skycrapers. 

You can't build the Fusion Power plant without the university.

Please let me know if you have any other questions.

It is really helpful.Thank you.

I just built the light house, when I started a new building within the area of effect from the lighthouse a sunny building popped up. Also do shinny buildings produce more tax income?
