A person who has inspired me in my major, is Alejandro Aravena. He's a young chilean architect who reciently won the Pritzker price, something like the Nobel of architecture.
I think I choose him as someone to admire, because he uses the architecture as a tool of thought, usually people who win the Pritzker creates amazing and georgeus buildings for enterprises or magnates, but he and his office ELEMENTAL, have done something different... they start creating an architecture for limited resources that not only suplies the needs of the people but also gives them an opportunity of making changes inside the projects after these are ready.
The project I like the most, remember me to a chilean expression when a house or any stuff it's really amazing, we use to say "la media casa", as something really cool... Aravena took that expression and create something called the Half House, the office designs the half of the house with all the basic rooms, like kitchen, bathdroom, bedrooms, living room, etc, and leaves people the other half, with all the basic structure, to gives them the chance of uses that anyway they want.
Maybe it's something not that attractive as Zaha Hadid or Frank Ghery, but this kind of thinking in architecture is what make real changes in our society, because it brings back to people the dignity that they deserve, not just four walls and a roof, they recieved a home, they aren't slaves of their house anymore, because now they can be free of living like they dreamed, and that's all I want to make as an architect.
