Typology App Series

Series of city guide apps based on Christ & Gantenbein's two books about typology in urban metropoles.


In 2012, architect studio Christ Gantenbein published an award-winning book about urban typologies discovered in Hong Kong, Rome, New York and Buenos Aires. Some years later a follow-up book was published also featuring Paris, Delhi, São Paulo and Athens.


How to develop and design a reproducible app that's completely based on print publications? What kind of additional features need to be thought of when releasing a digital version of an architectural guide?


Together with the client, I designed and developed city guide apps for eight metropoles.

To build a basic app where the concept could be reusable for every city, the publication's content structure and visual system needed to be analysed. Fortunately the book followed a clear structure and provides a digitally adaptable aesthetics.

The app offers a homescreen-like overview with selectable buildings providing the building's geographic location on a map.

building overview

When selecting a building, a picture of the building appears. By swiping left or right, other buildings can be visually inspected. In order to find the building, its location is shown on a map. Also there is a feature to save favorite buildings and to recall them later.

If more information about a building is requested, a modal view of information, building plans and additional pictures opens up.

The apps were featured in Hochparterre.

Every day these apps are downloaded from Apple’s App Store serving as a collection of uncommon urban architecture and as a handy navigator when it comes to visiting one of those metropoles. The apps can be downloaded for free from the App and Play Store:
