Mar Casa

TL;DR: Mar Casa by Deyaar is an award-winning AED 1.1 billion, 52-storey luxury seafront tower in Dubai Maritime City. Currently 48% complete with handover in Q4 2026, it offers 580 smart-home residences from studios to 4-bedroom royal penthouses, starting from AED 1.28 million. Featuring a sea-wave-inspired biomimicry facade, the project swept six categories at the Arabian Property Awards 2023 and offers a 76/24 payment plan with 24% post-handover.

Introduction

Mar Casa — Spanish/Portuguese for "Sea House" — is a landmark AED 1.1 billion (approximately USD 299.5 million) luxury residential tower developed by Deyaar Development PJSC, one of Dubai's most established publicly listed developers traded on the Dubai Financial Market. Rising 52 storeys directly along the Arabian Gulf coastline within Dubai Maritime City, the project was launched on 15 March 2023 and sold out in record time, confirming extraordinary market demand for prime waterfront freehold product.

Groundbreaking took place on 22 November 2023, and as of June 2025, construction had reached 48.42% completion with podium slabs fully completed, the tower core jumping system successfully executed, and typical tower slab casting well underway alongside mechanical, electrical, and plumbing (MEP) finishing works. Key subcontractors for joinery and aluminium works have been onboarded, and handover remains on track for Q4 2026 (December 2026).

Mar Casa swept six categories at the Arabian Property Awards 2023, including five-star awards for both High-Rise Residential Development and High-Rise Residential Architecture — a remarkable recognition that validates the project's design excellence and positions it among the most decorated residential developments launched in the UAE in recent years.

Location & Connectivity

Mar Casa occupies a premium seafront position within Dubai Maritime City, the 249-hectare reclaimed peninsula situated between Port Rashid and Dubai Drydocks on the Arabian Gulf coast. The district is master-developed by DP World and functions as a freehold maritime free zone with 100% foreign ownership, full capital repatriation rights, and zero personal and corporate income taxes. Over 280 companies are registered in the zone, and the district houses a 3.5-kilometre waterfront promenade and marina infrastructure.

Key distances from Mar Casa include approximately 3 minutes to Dubai Cruise Terminal 2 (Port Rashid), 6 minutes to the historic Bur Dubai mainland, 8 minutes to Jumeirah Beach and the Gold Souk, 9 minutes to Sheikh Zayed Road and Zabeel Park, 10 minutes to Sharaf DG Metro Station and the Dubai Museum (Al Fahidi Fort), 10–15 minutes to Dubai Frame, 15–20 minutes to Burj Khalifa, Downtown Dubai, Dubai Mall, and Dubai International Airport (DXB), and approximately 25–30 minutes to Dubai Marina and Palm Jumeirah.

Dubai Maritime City's road connectivity links the peninsula to Sheikh Zayed Road (E11) via a causeway and to the mainland via Sheikh Rashid Road (D75). The district's positioning between Port Rashid — one of the region's premier cruise terminals attracting millions of tourists annually — and the cultural heritage districts of Bur Dubai creates a unique blend of waterfront modernity and historic urban character.

Architecture & Design

Mar Casa's architecture represents a bold statement in biomimicry and biophilic design — the facade is directly inspired by the undulating motion of Arabian Gulf sea waves, with the building's silhouette flowing organically to create a visual harmony between structure and sea. This biomimetic approach replicates the fluid dynamics of ocean waves in the tower's curved exterior profiles, horizontal banding, and undulating balcony edges, generating a sculptural form that appears to shift and ripple when viewed from different angles.

Biophilic design principles are woven throughout the interior experience. Natural light, organic materials, greenery, natural colour palettes, and water features are integrated into common areas and unit interiors, creating a sensory connection to nature that the developer describes as "emotional luxury" — a design philosophy that prioritises psychological wellbeing and sensory engagement over conventional decorative opulence. The lobby is designed to capture the "graceful fluidity of waves" with a striking light installation as its centrepiece.

All 580 units are delivered as fully integrated smart homes featuring IP intercoms, smart access controls, smart lighting systems, and premium-brand appliances. The technological infrastructure is embedded from inception rather than retrofitted, ensuring seamless integration and reliable performance. The combination of biomimicry architecture, biophilic interior philosophy, and comprehensive smart home technology creates a product that is genuinely distinctive within Dubai's crowded residential tower market.

Unit Types & Payment Plans

Mar Casa offers 580 residential units across a comprehensive range of configurations, from compact studios to expansive royal penthouses.

Studios measure approximately 382 square feet, providing efficient waterfront living spaces. One-bedroom apartments range from 771 to 1,265 square feet, starting from AED 1,284,000 (approximately USD 350,000). Two-bedroom apartments span 906 to 3,095 square feet (the upper range reflecting premium duplex configurations), starting from approximately AED 4,200,000. Three-bedroom apartments measure 1,795 to 1,971 square feet, with 3-bedroom penthouses extending to 2,280–4,165 square feet and starting from AED 5,120,000. The pinnacle inventory comprises Executive and Royal penthouses in 4-bedroom configurations spanning up to 5,830 square feet, commanding valuations exceeding AED 14 million.

Duplex configurations are available in 2 and 3-bedroom formats at approximately 2,270 square feet each, offering the vertical spatial drama of double-height living within the tower framework.

Deyaar structured the payment plan as a 76/24 arrangement: 12% upon booking, 56% across 8 equal construction-phase instalments (approximately 7% each from September 2023 to May 2026), 8% at handover, and 24% post-handover spread quarterly over 24 months. A 100% Dubai Land Department fee waiver was offered at launch, significantly reducing total acquisition costs. This post-handover component enables investors to take possession and begin generating rental income while still paying the final quarter of the purchase price.

Amenities & Lifestyle

Mar Casa delivers an exceptional amenity suite anchored by two signature aquatic features: the Infinity Sand Pool — a sandy-bottom infinity pool with cabanas offering a beach-like experience against the backdrop of the Arabian Gulf — and the Sky Pool, an adults-only rooftop infinity pool with panoramic ocean views. A children's shallow pool, splash pad with fountains, and outdoor water play areas provide family-oriented aquatic recreation.

Wellness amenities include a gymnasium with yoga room, aerobics and yoga spaces, a spa and health club, sauna and steam rooms, and a meditation garden. Sporting facilities encompass a padel court (multi-purpose sports configuration), multipurpose sports grounds and lawn, and an outdoor playground. An indoor children's club provides age-appropriate recreation and socialisation.

Lifestyle and community spaces include a residents' lounge with sea views, a library, a co-working zone, a juice bar, BBQ grill areas, a multipurpose lawn, a games zone, and an organic grocery outlet. The building provides covered parking, smart home systems across all units (IP intercoms, smart access, smart lighting), CCTV security, and high-speed elevators.

Developer Profile

Deyaar Development PJSC is one of Dubai's most established publicly listed developers, traded on the Dubai Financial Market under ticker DEYAAR. Founded on 6 January 2001 as the property management unit of Dubai Islamic Bank (which remains the majority shareholder), the company commenced operations on 1 June 2003 and became a Public Joint Stock Company in May 2007.

Deyaar operates across four business units: Property Development, Property Management, Facilities Management, and Owners' Association Management. The company has completed over 30 projects across Dubai, managing more than 20,000 units in Business Bay, Dubai Production City, and other districts, with a total completed built-up area exceeding 7 million square feet. The developer is ranked among the top 10 property developers in Dubai.

Financial performance demonstrates sustained growth: full-year 2023 net profit reached AED 440.7 million (up 206% year-over-year), H1 2024 delivered AED 202.6 million net profit before tax (up 71% YoY), and H1 2025 achieved AED 266.6 million net profit before tax (up 31.6% YoY) on total revenue of AED 925.4 million (up 39.2% YoY). Notable projects beyond Mar Casa include Regalia Tower (Business Bay, AED 1 billion), Bella Rose (Dubai Science Park), Tria (Dubai Silicon Oasis), and the recently announced Downtown Residences — a 110+ storey, 445-metre supertall tower representing one of the tallest residential buildings planned globally.

Investment Potential

Mar Casa presents a strong investment case built on prime waterfront positioning, award-winning design credentials, and Dubai Maritime City's exceptional yield fundamentals.

Dubai Maritime City rental yields range from 6% to 8.5% gross annually for apartments, with studios and 1-bedroom units at the higher end of this range (7–8.5%) due to strong demand and relative affordability. Capital appreciation projections from independent brokers estimate 20–30% price increases from off-plan purchase to handover completion, driven by the district's ongoing infrastructure development, growing residential population, and constrained supply of premium seafront product.

The project's six Arabian Property Awards — including five-star recognitions for both development and architecture — provide tangible marketing currency that supports premium rental positioning and buyer confidence in the secondary market. Award-winning developments consistently command rental premiums over comparable but unrecognised buildings, as tenants and buyers assign value to third-party quality validation.

The 24% post-handover payment component (spread quarterly over 24 months) enables investors to begin generating rental income while still making payments, creating a positive cash-flow dynamic in the early ownership period. At starting prices of AED 1,284,000 for 1-bedroom apartments in a 52-storey seafront tower with smart home technology and resort-grade amenities, Mar Casa offers compelling value relative to comparable waterfront product in established Dubai districts.

The freehold ownership structure enables 100% foreign ownership, the zero-tax regime maximises net returns, and Deyaar's public listing on the DFM provides institutional transparency and governance standards that reduce counterparty risk for investors compared to privately held developers.
