We design
architecture
OOW is an award-winning Berlin practice designing and delivering buildings and interiors for commercial and housing—focused, bold, assured.
Polished Copper. Night-Green. Capturing the daylight and glowing at night.
260 Grad
A bar that captures the light of Berlin during the day and glows magically from within in the evening: With the rooftop bar 260 Grad, OOW shows how modern architecture makes optimal use of light and creates a unique atmosphere in a space.

“Casa Locarno is something like our business card turned into a house: sustainability, a prefabricated wood construction, frameless corner glazing... we did set OOW’s bar really high, right down to the last detail and in one of our first projects!”

Hidden Idyll
Living at Leopoldplatz
In the heart of Wedding, a residential oasis surrounded by greenery is being created on a former commercial site. In the immediate vicinity of the lively Leopoldplatz, our new residential building occupies a spacious property, quiet and hidden behind the first row of houses on Nazarethkirchstrasse. Fun fact: originally OOW was only asked to design to medical practices on the site by the client!

Conrade. Clarity. Radical.

“Minimalism as a design decision means maximum effort in terms of details.”

"Elegant proportions, high-end materials and sophisticated details: my ingredients for a perfect building. The art of architecture is to create designs that are both functional and well designed."
