What is ERA Architects’ Sustainable Renovation Project in Barcelona?

Design and Construction Process
The process begins with a thorough analysis of the client’s space and energy needs, followed by designing sustainable solutions tailored to those requirements. Clients get to see their future home in 3D and Virtual Reality, making the experience interactive and engaging. ERA architects handle everything from structural calculations to drafting the official project and requesting building permits from the City Council. Once the keys to the plot are handed over, the team takes care of the rest, providing weekly progress updates and ensuring the project stays on track.
Innovative Use of Materials and Technology
One of the standout features of ERA architects’ projects is the use of CLT wood, a sustainable and highly efficient building material. In 2022, the firm completed the first isolated house made of ytong certified as Passive House PLUS in Southern Europe—a milestone for Spain, Portugal, Andorra, and Southern France. By 2024, they had built three houses using modular wood systems, two of which are certified Passive House and constructed with CLT wood. This innovative approach not only reduces environmental impact but also enhances the quality and comfort of the homes.
Client Experience and Support
Clients receive a warm welcome into their new homes, complete with a professional photo session to capture the beauty and functionality of the space. ERA architects also provide data-driven insights to explain why the house is healthy and sustainable, helping homeowners appreciate the benefits of their investment. The team’s personal shopper service guides clients through material selection, ensuring every choice aligns with the overall design and sustainability goals. This hands-on support makes the renovation or building process smooth and enjoyable.

Looking Ahead: Tools and Innovations
ERA architects have developed the Positive House Calculator, a free tool designed to help people who might not directly use their services but still want to understand sustainable renovation better. This calculator will be presented on the radio at the end of October, aiming to spread awareness and empower more homeowners to make eco-friendly choices. It’s a perfect example of how the firm combines innovation with accessibility, making sustainability achievable for a wider audience.
