North-facing top-floor balcony: how to capture the sun from the roof?

Here's an example of a project involving a roof solution for a top-floor, north-facing apartment with balcony.

2 Patio-Solar reflectors receive the sun and project it onto the balcony and into the living space

From the street, a masonry band conceals the reflectors behind it.

Reflectors are assembled by a skilled craftsman with the appropriate tools and safety equipment (ladder, gloves, rope and harness).

Magic! The north-facing dwelling is now bathed in sunlight ☀️
