La Pedrera’s light wells are lungs in section: they deliver light and air to apartments, reduce humidity, and create visual delight with chromatic plaster.

Courtyard color palette


Strategies

  • Twin Courtyards: one wide, one slender; both orchestrate daylight.
  • Color Tuning: blues and ochres modulate brightness and warmth.
  • Layered Openings: windows and galleries stagger to avoid glare.

Color and Effect

Tone Effect Where
Blue‑green Cools light; reduces glare Upper levels
Ochre Warms evening tones Mid levels
Neutrals Balance transitions Lower floors

Experience

  • Stand at the base and look up: the sky becomes a lens.
  • From intermediate floors, watch light gradients shift across plaster.

The wells unify apartments vertically, making neighbors visible yet discreet.


Mini‑FAQ

  • Why painted plaster? To tune daylight and protect surfaces.
  • Does it help ventilation? Yes — openings and geometry promote airflow.
  • Is moisture an issue? It’s monitored; repairs are targeted.

Conservation Notes

  • Plaster requires periodic retouching; moisture is monitored.
  • Glass is maintained for thermal and acoustic control.
