  • Ayesa is ranked #74 in the prestigious Top World Architects Survey – the WA100 2024.

  • Ayesa ranks in the top 10 Architecture Firms for Central and Southern America at #6.


The WA100 2024 International Architecture Survey solidifies its status as a critical player in International Construction. 

23 January 2024, Ayesa, a global provider of engineering and technology services has been announced as one of the world’s largest architecture practices ranking number 74 in the prestigious Top 100 World Architect International survey.


The survey is completed annually by BDOnline and it ranks the top 100 architects by the number of architects they employ. It also comments on financial strength, Projects, and industry trends. 


Antonio Cubero Hernández Director of the Building & Architecture Division for EMEA, ASIA, and LATAM commented: “

Today marks a defining moment in Ayesa's journey as we are recognised among the world's largest architecture practices. After 25 years from the foundation of the Architectural Department in Ayesa, our commitment to innovation, excellence, and pushing the boundaries of design has propelled us to the prestigious #74position in the WA100 2023.

This achievement is a testament to the hard work and passion of every member of the Ayesa family. As we embrace this milestone, we remain dedicated to shaping a future where our architectural endeavors continue to inspire and redefine industry and sustainability standards. Together, we build not just structures, but legacies for our future


Ayesa's impact extends far beyond rankings; Their portfolio boasts a diverse array of major architecture and landscaping projects including the iconic Puerta Triana complex in Seville, Santiago Bernabeu Stadium Madrid, Cruzcampo Experience Factory, Amador Convention Centre - Panama, Chamartin Business Centre Madrid, Ar-Rimal, Al-Qadisiyah Monasyah and Twaeeq city Parks in Riyadh, St Barts Hospital and Audley Square in London, to name but a few. These projects stand as testaments to Ayesa’s commitment to transformative design and innovation.


From iconic structures that redefine cityscapes to sustainable developments that harmonise with the environment, Ayesa aims to shape the world through architectural excellence.

The results of the survey reveal that 75% of participants expect sustained economic expansion in the Middle East, with particular attention on the Kingdom of Saudi Arabia, where significant developments such as the Neom project and vertical city constructions contribute to the region's anticipated growth. India secures the second position in terms of expected economic development.

• Regarding the United States, two-thirds of respondents expressed optimism about its economic growth, marking a slight increase from the previous year.

• The survey indicates that 61% of participants anticipate growth in the global construction sector for the current year. However, there is a prevailing sense of caution regarding the growth prospects in Western Europe.

• The general consensus among respondents is that the Chinese market has experienced a decline, attributed to a collapse in the commercial sector and a cooling-off in the relationship between the United States and China.
