I’m Esther, the person behind ERA architects.
I’m a fluent English speaking architect based in Barcelona (also an official passive house designer).

Since I was 2 years old, I’ve been enjoying nature actively through sports.
My dad was a skiing instructor, so I spent my winters skiing and summers trekking or mountain biking.
When I was 16, I spent a school year in Canada where I was amazed by its kind people and the wild Nature.
After university I worked and traveled abroad delivering ambitious projects for awarded firms globally in places like Toulouse, Rotterdam, Seoul, Nanjing (China), Keelung (Taiwan) and Barcelona (Nou Camp Nou for Football club Barcelona).
The 2008 crisis brought me back to study to deliver more direct needs to people and our planet.

Today, as an English speaking architect in Barcelona, I’ve developed a method to understand the essential needs of our clients to DELIVER integrated, turnkey, unique, bio Passive House renovations and new builds through our teams of local professionals together with the help of existing subsidies.
I’m gonna let our clients speak so you can judge yourself (see below).

Happy to talk to you to start solving your problems while delivering your dreams.
