POLY MANNERS Architecture
About Poly Manners Architecture
Poly Manners Architecture (PMA), established in 2018 in Jeddah, Saudi Arabia, has cultivated a strong identity rooted in innovation, sustainability, and interdisciplinary collaboration.
From the very beginning, PMA has embraced an energy-conscious and environmentally responsible design philosophy, applying Passivhaus principles and sustainable frameworks to ensure performance excellence. Through our work, we seek not only to shape buildings, but also to create lifestyles, connect communities, and generate lasting value for future generations.
Origins & History
The story of PMA is deeply connected to the personal journey of Dr. Ahmed Abdulwahab Khan Al-Hashimi. After moving to France to pursue a Master’s and Pd.D. degree in Sustainable Architecture and Urbanism, he trained at Polyrhythmic Architecture in Bordeaux then he became main partner of PRA in 2014. This experience exposed him to the rigorous and innovative European approach to sustainable design and urbanism.
Motivated by this foundation, Dr. Ahmed envisioned creating a design house that blended global innovation with local identity. In 2018, he officially founded Poly Manners Architecture in Jeddah, Saudi Arabia, transforming his vision into a reality.

Expansion & Global Connection
PMA has developed strong intellectual and creative ties with Europe and beyond. It has worked across a spectrum of projects — urban masterplans, resorts, cultural developments, mixed-use complexes, and residential projects — aligning its practice with the ambitious Vision 2030 transformation of the Kingdom.
By establishing a regional house of expertise connected to its French origins, PMA has become a hub for knowledge exchange in architecture, urban design, and interior design, ensuring projects are both contextually grounded and globally competitive.
Integration with Sumou Group
In 2025, Poly Manners Architecture became part of Sumou Global Investment (SGI), the strategic investment arm of the Sumou Group.
Through this integration, PMA was designated as the official design and creativity studio of Sumou Group, leading architectural innovation and creative strategies across the group’s vast portfolio of projects in Saudi Arabia and internationally. This partnership reflects both the confidence in PMA’s expertise and its role in shaping the future of lifestyle, urbanism, and real estate development under the Sumou ecosystem.
Our Philosophy
At PMA, teamwork and interdisciplinary integration guide everything we do. From the earliest design sketch, structural, urban, and environmental experts collaborate to ensure holistic, innovative, and sustainable solutions.
Our ambition transcends architecture:
-
To create better ways of living,
-
To foster responsible consumption,
-
To build meaningful human and cultural connections,
— always ensuring that our work leaves a positive legacy for future generations.
