Martonffy Architecture Studio (MAS) is a full-service architectural firm and certified Micro-LBE/MBE in San Francisco.

With two decades of experience, spanning hospitality, workplace, housing, and high-rise towers, we bring a blend of design experience and technical capabilities — including BIM — to deliver excellent design and project execution.

MAS was founded in 2012 to explore a more diverse body of work applying the technological skills that principal Claudio Martonffy honed during his time with Skidmore, Owings and Merrill. It is a vision rooted in his passion for design and documentation – and a keen grasp of the connection between the two. The team has very different backgrounds, yet they are united by their shared design values. With global perspective and seven languages at our disposal, they have tackled projects ranging from tenant improvements for retail, restaurants and offices to designs for custom residential and multifamily housing. They provide full design services including concept design, feasibility studies, construction documents, obtaining permits and approvals, review during the bid and negotiation phase, and construction administration. Since 2016 we have delivered all of our work in BIM.

As Architects, MAS works in a collaborative, integrated role leveraging our strengths in the following areas:

  • Agility in applying a breadth of design technology including BIM, Rhino, V-Ray, Grasshopper, and more to resolve design problems efficiently and elegantly – and to optimize energy performance, budgets, and construction.

  • A demonstrated record of successfully completed projects in interior architecture, often delivered on accelerated schedules and in technically complex settings

  • Experience attaining project approvals in San Francisco as well as cities around the country, working closely with planning and building departments, airport authorities, and health departments

  • A reputation for communicating effectively and proactively with consultants, associate architects, builders and fabricators, from design through construction.
