§ Team

Built by people who know this lake.

Atitlán Build is a small practice with deep roots. Every project is led personally by Stefan and Antonio, supported by a curated network of specialists we have worked alongside over many years.

§ Core team

Every project led personally from start to finish.

We do not hand work off to junior staff. When you work with Atitlán Build, you work directly with the people responsible for the outcome.

Stefan Bird

Managing Partner and Founder

Stefan's background is international real estate development. He began his career as an estimator at Moss and Associates in Fort Lauderdale, responsible for winning over $1.2 billion in multifamily, hotel, and commercial projects across Florida. He then joined ZOM Living as Development Manager, overseeing the siting, design, entitlement, construction, and lease-up of over 2,000 apartment units across six properties, including Bezel at Miami Worldcenter, Seazen at Rocky Point in Tampa, and Baldwin Harbor in Orlando.

Stefan holds a Master of Science in Real Estate Development from the Massachusetts Institute of Technology, where he received the Gerald Blakeley Fellowship and cross-registered into courses at Harvard Kennedy School, Harvard Business School, Harvard Law School, and the Harvard Graduate School of Design. His capstone won 2nd Prize in the GSD's 2020 Plimpton-Poorvu Design Competition. He was also one of five participants in the 2020 Urban Land Institute Randall Lewis Healthy Building Mentorship Program. He also holds a Bachelor of Science in Construction Management from the University of Florida, a Certificate for Financing and Deploying Clean Energy from Yale, and is a LEED Accredited Professional Building Design + Construction.

Stefan relocated to Lake Atitlán in 2023 and has since acquired and developed multiple properties in the region, including a renovation in San Pedro La Laguna, a 14-key wellness retreat center in Tzununá, and advisory roles for WuWei Village and Nido Atitlán.

Portrait of Antonio Semaj, Lead Builder and Site Superintendent at Atitlán Build

Antonio Semaj

Lead Builder and Site Superintendent

Antonio was born and raised in Tzununá and has spent his career building with local materials and local crews at Lake Atitlán. He reads sites and drawings together, catching the gaps between what is drawn and what the ground will support. His early involvement in every project is what keeps our budgets honest and our detailing real.

Prior to working at Atitlán Build, Antonio was the General Manager at Loma de Tzununá, a flagship 28-bed retreat center on Lake Atitlán. He was responsible for all aspects of the business — construction and maintenance, food and beverage, guest experience, and reservations. Before that he owned and operated a small construction business, building five homes in two years. He started his career as a tour guide, which is where he became fluent in English and got to know the pueblos around the lake by heart.

§ Safety and worker dignity

Every worker is the breadwinner of a family. We build accordingly.

Behind every tradesperson on an Atitlán Build site is a family depending on them to come home safely. That is not a statistic. It is the reason we treat safety as a standard of care, not a compliance requirement.

Every project begins with a written safety plan. We hold weekly safety meetings on site regardless of project phase. Key tradespeople are given ongoing opportunities for skill development and upskilling, because when the people building the work grow in their craft, the work gets better and their livelihoods get more secure. Both things matter.

Project Safety Plan

Every project starts with a written plan. Hazards identified, protocols established, responsibilities assigned before work begins.

Weekly Safety Meetings

On-site, every week, every phase. Not a box to check. A culture to build.

Upskilling and Growth

Key tradespeople receive ongoing training and development. Better skills mean better work and real upward mobility for the families behind them.

§ The community as a team member

We build within a community, not just on top of it.

The communities surrounding Lake Atitlán are not a backdrop to the work. They are participants in it. The tradespeople, the material suppliers, the neighbors who live adjacent to every project we build — these relationships shape what is possible and how we conduct ourselves. We believe construction should participate in the community, through permitted work, fair wages, and genuine relationships, not extract from it.

§ Our standard

We measure success by more than what gets built.

A project done right leaves the client, the crew, and the community better than it found them. That is the standard we hold ourselves to on every engagement.

Ready to meet the team?

The first conversation is free and there is no pressure. We want to understand what you are trying to build and whether we are the right people to help.

We measure a successful project not just by what gets built, but by whether we end it better friends than when we started.
