About Open Window House

Open Window House is an informational site about natural light in interiors, with a focus on homes in Germany. It collects plain notes on how daylight enters a room, how its character depends on window orientation, and how interior surfaces carry it further into a space.

What the site is

The content is written as reference reading rather than advertising. Each article sticks to general, observable principles of daylight and architecture, and points to publicly available references for readers who want to go further. Where exact figures vary by location or building, the text describes the tendency rather than inventing a precise number.

How it is organised

Three articles cover the main angles: window orientation, reflective surfaces, and seasonal daylight across the year. Each can be read on its own, and they link to one another where the topics overlap.
