Who we are

The Principal Architect

Architect Edward Co Tan has been a licensed architect since 1984, the same year he earned his degree in architecture from the University of Santo Tomas. Apart from that, he is also a licensed Real Estate Broker and a licensed Real Estate Appraiser.

A registered APEC Architect and ASEAN Architect that currently holds a membership with the United Architects of the Philippines (UAP), whose earnest interest in the development of other Asian countries led to his associate membership with the Singapore Institute of Architects (SIA).

Throughout his 34 years of experience, he has covered and spearheaded projects of different typologies varying from residential, commercial, institutional, and leisure buildings. With his keen attention to value space planning and value engineering, he led his firm to become one of the top architecture firms in the country. His involvement in different high-rise projects brought up his practice of Structure as Architecture, a philosophy centered around efficiency.

He has a great interest in geometry and principles of modernism, which brought up his expertise in designing projects focused on the utilization of space, cost, and operational efficiencies. Realizing how architecture dictates, manipulates, control, and influence human behavior, he poses a strong conviction on natural essence being the most important factor in revealing the best out of a material, thus making a building— a structure, an architecture.

Location: Tagaytay

Hidden in the mists of Tagaytay is one of the firms proud achievements. This tropical mansion was inspired by Balinese architecture with touches of the Filipino spirit. It captures a sense of openness with pavilions that are interconnected with one another, and a plan inviting the outside to the interior.

Wanakasa was intricately designed. Many of the materials and furniture were personally handpicked by the owners—a melting pot of culture from Africa, China, Indonesia, Vietnam, and of course the Philippines. The Architect and Interior Designer, Maria Agnes Lambuson, gracefully brought this together to become a perfect vacation home for the owners, being enthusiasts of Balinese Architecture.

Wanakasa was awarded best leisure architecture in the Philippines by the Asia Pacific Property Awards for 2016-2017. Apart from than that, Sorrell Publishing Company published a book dedicated entirely to the mansion.
