The "KRUUNU" proposal for the Sara Hildén Art Museum competition in Tampere, Finland, was developed in 2022. The architectural concept is grounded in a recurring square motif and orthogonal rationality, evident in the spatial composition, façade ornamentation, and the design of the upper gallery's skylights. The building's uncompromising architecture features an unyielding stone exterior complemented by warm wooden interiors, reflecting the strong yet warm personality of Sara Hildén.​

An excerpt from the jury's evaluation states:​

"The art museum proposed has been carefully and logically developed both in terms of the cityscape and internal functions. The merits of the entry in terms of the cityscape and the functions are based on the fact that the above-ground section of the building only has three floors and the size of its square footprint is sufficiently large to accommodate the functions on the floors in a natural manner."
