Danish architects Mathias Mentze and Alexander Ottenstein of Mentze Ottenstein maintain a practice rooted in research with a special sentimentality toward historic architecture. Which is why they were enlisted in the renovation and restoration of a large, 275-square-meter apartment in Copenhagen’s Frederiksstaden neighborhood. The building was developed by historic architect Ferdinand Meldahl in the late 19th century in harmony with the surrounding buildings: it faces the famed Marmorkirken (The Marble Church, a rococo-era church also known as Frederik’s Church) and is just near the Amalienborg Palace.
The client, a young woman looking for a home base in Copenhagen, was keen on restoring the original 1870s charm of the apartment. The apartment had been redone in the 1990s with design choices reflective of that era and was designated as a listed building around that time. The architects explain: “When a building is listed in Denmark, it takes effect from the moment the decision is made, including all the non-original details that have been added over the years. This was a challenge as we wanted to bring it back to its original glory, and not how it was changed and damaged up until the 1990s.” Mentze Ottenstein proceeded with extensive research on both Ferdinand Meldhal and on the specific apartment within the building compound. Working with a historic building in Copenhagen required a close dialog with The Danish Agency for Culture responsible for listed buildings. “Everything had to be designed and discussed again and again.”

Restoring the apartment was a process of uncovering: revealing original pine plank flooring and stripping back 150-years-worth of paint to original plasterwork details. The kitchen is quintessential Danish elegance and was an opportunity to balance the historic with modernity. “The kitchen had been through a lot of changes, so it was the room with almost nothing to build upon. There was no record of how the original kitchen would have looked like,” explains Mathias. The kitchen is kitted with a custom range surround, custom cabinetry and furniture and a wall of Delft tiles. “The design became a re-imagination of how a kitchen in this kind of apartment might have looked like.”
