The 300-bed Dr. Sami Ulus Children’s Hospital is planned to replace the existing hospital in Ankara’s Altındağ district, responding to changing healthcare technologies and contemporary spatial requirements. With a total enclosed area of 83,000 m², the hospital comprises basement and lower-ground levels, a ground floor, and nine upper floors, with a building footprint of approximately 11,500 m².

The design places particular emphasis on the psychological impact of the healthcare environment, especially for children and their families. Colors, materials, spatial volumes, and architectural elements are developed to create a welcoming and reassuring atmosphere, with a consistent design language extending from the interiors to the exterior façades.

A colorful design concept introduced at the hospital entrance continues throughout the interior spaces and façades, aiming to strengthen a sense of comfort, safety, and belonging while maintaining appropriate levels of privacy. The selection of colors and materials is informed by principles of biophilic design, incorporating references to nature to support a calming and restorative environment.

Warm, natural tones are used particularly in spaces such as intensive care and consultation rooms, where comfort is essential. Stylized patterns inspired by natural forms are incorporated throughout the hospital, reinforcing the biophilic approach. The overall design seeks to create a healthcare environment in which children and their families can feel comfortable, secure, and at ease.
