This project reimagines terraced housing by developing an innovative typology that directly responds to a challenging site and rectifies the failures of classical layouts. Located on a 7808 m² plot in Szczecin, Poland, the design was constrained by a 110kV overhead power line, which created a large, angular no-build zone, and by local guidelines requiring steep (min. 25°) roofs within a 9.5m height limit.

Our solution is a multi-layered strategy:

1.The "Interlocking and Setback" Unit: We rejected the standard, flat-faced terrace. Instead, the individual segment is "cut" and "shifted," creating an interlocking form. These units are then paired, creating the visual impression of fewer, larger structures. Each pair appears as a single house with one garage and two separate entrances. This intelligent setback integrates parking by creating a recessed forecourt that hides two parking spaces (one in a garage); it allows for a narrower, more efficient plot, enabling a higher density (33 units) on the site; and it results in a more functional interior layout.

2. The "Diagonal" Site Plan: To solve the primary site constraint, the housing rows are rotated into a "diagonal urban plan." This adapts the development to the angular boundary of the power line's exclusion zone, maximizing the buildable area. This rotation also creates a well-defined, functional entrance zone for the complex, accommodating guest parking, waste disposal, and mailboxes. Furthermore, the diagonal orientation yields significant environmental benefits, providing optimal East-West exposure for all units.

3. The "Smart" Mansard Roof: A modified mansard roof meets the 9.5m height and 25° slope requirements. This form maintains a clean aesthetic by hiding all technical utilities (chimneys, PV panels, A/C units) on its flat top portion. It also provides a larger, usable attic area.

The result is a complex of 33 homes that transforms a technically difficult site into a vibrant community, creating a housing model that is both pragmatic and architecturally compelling.
