As its successful predecessors, Powershop 4 unveils the latest and greatest retail interiors from all over the world. Featuring around 120 shop and showroom interiors, the book shows the current trends in this field. Included projects range from supermarkets to bakeries, from luxury fashion boutiques to sneaker shops and jewellers. Each design is featured on two to six pages that are filled with photos, drawings, sketches and of course a description of the design.

The project text explains how the designers made the client's store and products stand out, how they incorporated the client's identity into an environment, how the concept developed, what materials were used and how the design was executed. The showcased work is created by world-famous designers as well as young design studios and is selected based on their original concept, creativity, innovative approach or the project's unmistakable wow-factor. The shops featured have been realised by designers from around the world, including Architecture at Large, Jaklitsch / Gardner Architects and Fabio Novembre, and feature retail spaces from Levi's, Mykita and Mercedes-Benz.
