APDG is a design studio seamlessly integrating architecture, interiors and landscape to create holistic spatial experiences. Established in 1985 by Founding Principal Arlen P. de Guzman, APDG was awarded the AIA International and was the former President of United Architects of the Philippines (UAP) as well as former President of Philippine Institute of Interior Designers (PIID).

APDG work strives for tranquility and calmness qualified by space, light and structural order. Architectural expressions are distilled, to capture the spiritual essence of ‘place’; while architecture and interior are inspired by the cultural and climatic nuances of context;  integrating landscape, water features and blurring the boundary between inside and out. Spaces are characterized by lush gardens, water courts and air wells, effecting a sensuous engagement with the elements. A sensitivity to the inherent beauty of natural materials is expressed through clarity in construction details, and elemental architectural expression.



APDG seeks to produce refreshing interior design and architecture that is tranquil, inspired by nature, yet human in  scale.

Our projects both  derive inspiration from, and relate closely to nature. Structure, materials and technology are used to express as seamless a transition as possible between inside and outside. The resulting designs are both responsive and responsible to the site and its occupants, with consideration being given to the integration and preservation of the surrounding natural environment.

The practice makes extensive use of sustainable design technologies, and both passive and active design principles inform all design decisions with the intent to create long lasting, timeless interior design & architecture.
