A minimalist retreat in Berlin

A minimalist oasis of calm sits atop a heritage building in Berlin, the home of a globe trotting entrepreneur with a killer African art collection. German interior architecture firm Dreimeta (who also designed Tuesday's La Granja in Ibiza) has created a home as retreat, an escape from high powered, fast paced lives, a place to be surrounded by authentic materials and treasures from travels, a beautiful space to collect and recollect.
