IFUB*, short for Institut für u. Baukunst, is an architecture and interior design firm founded on May 1, 2012, by Johannes Krohne and Bernhard Kurz. With offices in Berlin and Munich, the firm has grown to a team of eight professionals. IFUB* specializes in housing and office projects, with a particular focus on refurbishments, though they also undertake new construction.

The firm's philosophy centers on prioritizing people over profit and design, emphasizing a holistic approach that integrates architecture and interior design. IFUB* has developed its own handbook with ten parameters for architecture that benefits the common good, reflecting their commitment to sustainable and socially responsible design.

Notable projects include the conversion of a former chocolate factory in Berlin's Neukölln district into an open-plan office space, preserving historical elements while incorporating modern functionality. Another significant project is the "Hausfuchs" semi-detached house in Vaterstetten, featuring distinctive white aluminum roofs.

IFUB* also engages in innovative residential developments, such as the D2 project in Berlin-Neukölln, a new construction for a housing cooperative. The firm's work extends beyond traditional architectural services, encompassing energy consulting and urban planning.

Despite starting without wealthy connections, IFUB* has steadily grown through a focus on quality work and effective online presence. Their approach challenges conventional industry practices, advocating for a shift towards increasing the common good in the construction sector.
