About us

JAMES&MAU is an international architecture firm based in Spain and Poland with associated offices in Chile and Colombia.

The company brings together expertise in several areas such as architecture, construction, and real estate development in order to offer full-service support for the development of projects both for individuals and enterprises.

JAMES&MAU is widely experienced in design, work on-site and building permits, with a strong focus on modular industrialized architecture and construction, applying bioclimatic and sustainable concepts.

In a global context, we humbly try to contribute to the biggest challenge humankind ever had which is global warming. Our tools are a common sense bio-climatic design that takes advantage of the particularities of the local climate and tries to match them with the needs of the users, the use of local materials and construction crews, as well as the use of renewable energies and eco-friendly materials.

In a closer context, we devote our efforts to the happiness and welfare of the users of our buildings by turning their needs and wishes into user-friendly spaces. Parallelly we try to make the best of the businesses when developers are the initiators of the projects.

We believe that every project deserves its own architectural language derived from the uniqueness of the site, its climate and history, and the clients and/or users. In this sense, no project should aesthetically look like another since aesthetics are just a result of the unique architectural language of each project.
