Map of apartment building management companies in Ljubljana

Some time ago, I did an analysis of building manager companies for dnevnik.si. It was an interesting project, because there’s much controversy surrounding this topic. Some of these companies have been in bitter disputes with the residents and competing companies over their business, generating a lot of newspaper coverage.

We did a simple analysis to deterimine market shares and relative winners and losers in comparison to market leader. Here’s an image of final page in the newspaper. Click it to open the PDF.

We also did a lot of other stuff that didn’t find their way into the final article. I’m now publishing an interactive map, showing the distribution of these companies across town. There’s usually one per apartment building. For this map, I only processed the apartment buildings with more than one apartment, because that’s where business is.

Click on the image below to open the map in a new tab, or click here.

Click on a building, and a popup will display the address and relevant history. It’s also possible to choose a company, and the map will refresh, displaying only the buildings in the selected company’s management. There’s also a button to display only those buildings where managers changed in the interval from years 2005 to 2015.

There’s also a graphic showing how many buildings a company gained from other companies. Here’s a screenshot. Click will take you to the same page as image above.

The original dataset came from GURS, but then we were able to acquire an update from the city government. We decided to use that, because they gave us three different updates, each five years apart, from which we were able to calculate the differences. You can see them in table below.

• total flats: how many apartments are managed by a company,
• gained: how many flats were gained by the company from 2005 to 2015,
• lost: how many flats were lost by the company from 2005 to 2015.

Original data is here.
