How We Work

We approach each project as a partnership of shared vision and passion, following a collaborative process that is mutually beneficial for our clients and the firm.

Collaboration is a driving force at AD&V®. Our entire team gets involved at the initial stage of every project. We work closely with each other and in partnership with our clients to ensure they get the best results. Our integrated practice offers experts in key areas including architecture, interior design, and green initiatives.

We do not impose a style on our clients. We listen to their concerns, identify their pain points and use our expertise to provide functional and efficient solutions and designs.

Throughout the design process, we are conscious of the financial realities that can shape projects. We understand our design has to be cost effective and realistic in order to be successful.

We are conscientious global citizens in a world of limited resources that our collective actions threaten to exhaust. We believe that, as architects and designers, it is our duty to make more responsible choices with our designs.

We must walk the walk and live and work by sustainable practices. Every responsible choice that we make—or help our clients make—is our small-yet-significant way of contributing to the greater good.


We relocated our main offices to an early 20th-century building in the historical area of Santurce in San Juan, Puerto Rico.

As part of our ongoing effort to create a healthier environment, lower operating costs, minimize waste, conserve water and energy, and reduce our carbon footprint, we renovated and retrofitted an existing structure. Our office is the first architecture and interior design firm in Latin America to be LEED® PLATINUM (Leadership in Energy and Environmental Design) certified by the U.S. Green Building Council.


Our offices are a showroom for the benefits of green initiatives. Sustainable buildings are better for people and for the planet. But they also are better for our bottom line.

Energy efficiency saves money, but there is another aspect that makes sustainability more profitable. When a place of work has the right amount of light—not too bright, not too dark—and the right temperature—neither too cold nor too hot—team members can focus on their jobs and be more productive. In addition, their experience of their work place and their jobs is improved, resulting in a better quality of life. Happy employees are productive employees.

Our Competitive Advantage

Act No. 20 of 2012, known as the Act to promote the exportation of services, provides attractive tax incentives for companies that establish and expand their export services businesses from Puerto Rico. Álvarez-Díaz & Villalón® (Alvarez-Diaz + Group, PSC) can share with our clients the benefits of only paying 4% tax for all exporting services designed in the island and was the first architecture and interior design firm to offer this advantage.
