Haso Myllynkivi is a project designed for the Helsinki City Housing Production Agency (ATT), representing infill construction in eastern Helsinki. This project consists of a single residential building and is part of an infill plan, where two existing slab buildings are replaced by a new block consisting of five larger residential apartment buildings and an underground parking facility under a common courtyard.

One of the key design challenges was integrating this separate project into the already planned block complex and blending it with the surrounding old buildings. Typical challenges related to modern housing construction, such as a thick building structure, were addressed by taking advantage of corner apartments with multiple orientations.
