Mubadala and Aldar Announce $16bn Expansion of Al Maryah Island

Mubadala Investment Company and Aldar have unveiled a landmark AED60 billion ($16 billion) development plan for Al Maryah Island, marking the largest expansion in the island’s history. The project represents a major step in Abu Dhabi’s long-term strategy to strengthen its position as a global financial, lifestyle, and investment hub.

The expansion will transform the last remaining undeveloped plot on the northern side of Al Maryah Island, covering nearly 500,000 square meters. Once completed, the masterplanned district will deliver approximately 1.5 million square meters of mixed-use space, including offices, residential units, retail destinations, hospitality assets, and leisure infrastructure.

A New Mixed-Use Financial and Lifestyle District

Designed to integrate business, living, and leisure, the development aims to elevate Al Maryah Island’s international appeal while reinforcing its role as Abu Dhabi’s premier commercial and financial address. The project is expected to attract multinational corporations, global investors, and high-net-worth residents seeking waterfront luxury combined with world-class infrastructure.

Major Expansion of Abu Dhabi Global Market (ADGM)

A cornerstone of the development is the significant expansion of Abu Dhabi Global Market (ADGM), one of the world’s fastest-growing international financial centers.

The new masterplan will:

• Double ADGM’s current Grade A office stock
• Add more than 450,000 square meters of premium office space
• Support rising demand from global firms, financial institutions, and professional services companies

ADGM currently hosts over 11,000 registered entities and employs nearly 40,000 professionals, reinforcing Abu Dhabi’s growing influence in global finance, fintech, and asset management.

Rising Demand for Luxury Waterfront Residences

Residential demand on Al Maryah Island continues to grow as international buyers and residents are drawn to its luxury waterfront lifestyle and proximity to major business hubs.

The expansion will introduce:

• More than 3,000 new premium residential units
• A mix of high-end apartments and branded residences

These homes will complement existing luxury developments already underway, including W Residences and St. Regis Residences, further positioning Al Maryah Island as one of Abu Dhabi’s most exclusive residential destinations.

Enhanced Retail, Leisure, and Waterfront Experiences

Building on established attractions such as The Galleria, Cleveland Clinic Abu Dhabi, and the ACTIVE sports hub, the new phase will significantly enhance the island’s lifestyle offering.

Key additions include:

• 40,000 square meters of high-end retail and dining
• A state-of-the-art marina
• A redesigned waterfront promenade
• A signature bay fountain capable of water displays reaching 75 meters high
• New public spaces for events, leisure, and outdoor dining

These elements are designed to strengthen Al Maryah Island’s role as a destination for both residents and visitors.

Abu Dhabi Convention Centre and Hospitality Growth

A major highlight of the expansion is Abu Dhabi’s new Convention Centre, envisioned as a world-class venue for international events, exhibitions, and conferences, including Abu Dhabi Finance Week.

To support increasing visitor numbers, additional luxury hotels will be developed, complementing existing five-star properties such as:

• Four Seasons Abu Dhabi
• Rosewood Abu Dhabi

This hospitality growth is expected to further boost tourism, business travel, and international exposure.

Infrastructure and Connectivity Upgrades

The masterplan places strong emphasis on accessibility, sustainability, and pedestrian comfort.

Infrastructure enhancements include:

• 2.5 km of climate-controlled walkways
• Over 12,000 parking spaces
• Green areas covering 20% of the district
• Three new bridges connecting Al Maryah Island to Reem Island and Abu Dhabi mainland
• Direct access to Saadiyat Island in under 10 minutes

Construction of these infrastructure upgrades is expected to begin in 2026.

Strategic Partnership Between Aldar and Mubadala

The expansion is being delivered through a joint venture owned:

• 60% by Aldar
• 40% by Mubadala

The two entities share a long-standing partnership, with previous collaborations including Al Maryah Tower, One Maryah Place, and a major retail venture that will operate flagship malls such as The Galleria, Yas Mall, and Saadiyat Grove Mall.

A Defining Moment for Al Maryah Island

The AED60 billion expansion represents a defining milestone in the evolution of Al Maryah Island. By combining financial infrastructure, luxury living, retail, hospitality, and cultural venues, the development positions the island as one of the Middle East’s most important destinations for business, investment, and lifestyle.

As Abu Dhabi continues to diversify its economy and attract global capital, Al Maryah Island is set to play a central role in shaping the emirate’s future.
