Purpose, program & users
Purpose
It was commissioned by Pera Mila and Roser Segimon as a luxury apartment building in which they can live in and rent out. The main floor was where the owners planned to live in while they would rent out the other apartments to wealthy tenants. [1]
Program
The original design of the building included two different residential areas with independent entrances, four floors of apartments, large interior courtyards and a basement garage. The basement was originally designed for carriages. The roof has ventilation towers and chimneys. [1]

The primary users were the Mila family and other affluent families that rented the apartments below. Today, the primary users are the few residents that still reside in the building. [3]

Casa Mila, the Spirited Being
I find it especially noteworthy the way the trees blend in with the building. Their natural form joins with the building’s undulating shape.

Unique in its nature
I strong contrast between the leaves less trees and the fluid building is especially noteworthy. The dark widows with many shaded created a omnesque feel.

Published research
Antoni Gaudí i Cornet: A Life Devoted to Architecture by Rainer Zerbst.
Zerbst describes Casa Mila as Gaudi’s most experimental works and hilights its importance in the development os human architecture skill and values. He discusses the concaving stone facade, irregular walls and floor plans, roof terrance. He shows how Gaudi moved away from traditional rectangular apartment building design that focused on just the user and cost of the building. The building’s strange structure allowed the flexible interior spaces that don’t limit themself to a specififc function. It allows the residents to create spaces that best suit them. [8]
Gaudí: A Biography by Gijs van Hensbergen
Van Hensbergen compares and contrasts Casa Mila to Gaudi’s life, the Barcelona social scene, and the wealthy patrons of the building. He explains the building was highly conteroversial because of its unconventional facade and design which challenged what elite housing looks like in European society. The book comapres Gaudi’s bigger architectural values of form and rythem to the building’s identity itself. Many others ciritics belived that the building’s function were a afterthought, but Van Hensbergen goes against that notion. He belives that both the art of the buildind and the function coexistence seamlessly. [9]

CHarcoal Drawing
Draw the building

The artwork is 24″ x 36″ done in charcoal
I think I truly captured the feeling and the movement in the building. My drawing is very impressionistic, and fluid with its stroke. Using charcoal allowed me to focus on the shapes of the building rather than focusing of color. It allowed for me to create strong gestures and create a building that puts the feeling of the building onto paper. I really like the unfinished aspect of the drawing.
