Hyphen partnered with Real I.S. for the transformation of the Lotte Gold office building in central Berlin.
Originally built in 1930/31 and refurbished in 2000, Lotte Gold is a distinguished office and commercial complex in the heart of the German capital. The development consists of two architecturally complementary sections: a prominent six-storey corner building with a staggered upper floor and an eastern wing along Rudi-Dutschke-Straße. The basement houses technical facilities, tenant storage, and parking, while both sections feature elegant courtyards.
In 2023, our team partnered with Real I.S. to transform this historic building, providing a full architectural design service to enhance functionality and aesthetics. Our scope included reorganisation and design of the office spaces, new design of the façade, and a feasibility study for roof expansion for residential use.
Our approach to the office redevelopment balanced architectural heritage with modern efficiency. Spanning over 100 metres, the redesigned façade respects the original 1930s ribbon windows while incorporating high-performance insulation and ventilated cladding to meet Germany’s Building Energy Act (GEG) standards. The natural stone façade at ground level is crowned by a striking golden canopy, creating an inviting entrance.
The ground floor offers retail spaces, while the upper floors feature premium offices with modular units ranging from 290 to 620 m². The interior design supports flexible layouts for private offices or open-plan spaces. Refined, sustainable finishes and integrated infrastructure create an optimal working environment with ample natural light, superior ventilation, and advanced climate control.
At every stage of the project, our team worked closely with Real I.S., offering expertise and a shared vision to respect the building’s past while maximising its future potential.
