Alter Interiors

Founded by Steffie Oehm and Jenny Magdol, Alter Interiors is a full-service interior design studio based in San Francisco. With a focus on spatial innovation and sustainable material practices, we create dynamic spaces that have the potential to adapt to changing needs over time. We thrive on context and believe a well-informed space is designed with the environment, its occupants, location and history in mind.

We love taking elements from the past and bringing them into the future. We deeply enjoy the collaborative nature of design and have a deep appreciation for architectural detailing and craftsmanship.
