About Us

For over 35 years MGA has been involved with the planning and A/E design of aviation related commissions. Working with some of the finest consultants in their fields, one of the firms projects of major significance was the expansion of the Luis Muñoz Marín International Airport, the Gateway to San Juan, Puerto Rico in which MGA has participated in every mayor development since Eastern Airline's 11 Gate Unit Terminal in 1985.

Located in Carolina, Puerto Rico, MGA maintains a relatively small professional staff, an organizational policy which guarantees the personal involvement of Principal - Manuel Goicoechea-Castedo in every project as well as a fluid working relationship between associates, staff, clients and consultants. Complementing the office is a network of specialized consultants who are brought together as members of project teams as the specific assignments may require.

Based on respect for the environment, the specific site and its context, climate and building technology, MGA is commited to an open-ended approach to planning and architecture that takes place on two interacting levels. the first level attempts to clarify a set of attitudes about "what" to do, based on a firm understanding of the particular nature of each problem. The second level is concerned with the making of appropiate decisions about "how" to get it done.

The search for what to do is based on issues, fundamental principles, context and forms while the exploration of how to do it is based on implementation strategies, budgetary constraints, and a thoughtful design execution. The ultimate stress is on functionality and design excellence. Our goal is to provide each client with a built interpretation of their individual programmatic requirements that reflects their unique character and personality within budget and on schedule.

Manuel Goicoechea Castedo

Founder & Principal

Manuel Goicoechea has over 35 years of experience in a wide variety of projects in the USA and overseas. A strong asset to any project is his design capability, attention to project budget and schedule, which has been developed through the execution of numerous design commissions.

Most projects have included not only the integration of a design concept into a functional architectural design solution but also encompassed providing design solutions to the needs of concessionaires, federal and local agencies, as well as coordinating with those that have a firsthand interest in terms of regulating and / or operating facilities. Coordination of all these responsibilities concurrent with a wide range of actual construction experience has been one of Mr. Goicoechea's strongest assets.
