In Argüelles, a neighbourhood defined by tree-lined streets and proximity to the university quarter, this penthouse sits within a 1975 building served by lift. The apartment commands a generous footprint across multiple levels, structured around generous terraces that bring light and air into the interior spaces. The layout unfolds through distinct zones. The main living area opens onto terracing, creating a fluid transition between inside and outside. The kitchen sits integrated within the sequence of social spaces, while the sleeping quarters are distributed across the upper level, comprising five bedrooms and five bathrooms—each bedroom served by its own bathing space. This arrangement prioritises privacy and practicality without sacrificing the coherence of the whole.
