SIERRA+PEROJO is a studio founded by architects Julio Sierra and Ana Perojo, and interior designers Blanca Sierra and Rosana Sierra, which is committed to responsible and efficient architecture.

It is made up of a multidisciplinary team specialising in passive and sustainable architecture, developing urban planning, architecture and interior design projects.

We love our work. Each commission is a new adventure, a process in which the relationship with the client helps us to get to know their needs in depth.

We design under the passivhaus standard providing solutions adapted to the requirements of each project.

This work methodology encourages the development of very low energy consumption, minimising CO2 emissions and reducing the heating and cooling demands of buildings.  

Design is intention. Our work method is based on combining sustainability and eco-efficiency criteria, seeking to create spaces that have a positive and direct influence on those that inhabit them.

We design healthy buildings, trying to improve people's quality of life, seeking to create meeting places, generate spaces that improve connectivity and community life, prioritising the use of natural materials, which contribute to improving health and at the same time reduce energy consumption.

We try to make people's lives a little better, we have the firm conviction that buildings should take care of us.
