Banana Island — The Ultra-Luxurious Private Artificial Island

Overview

Banana Island is a private artificial island built off the coast of Ikoyi. Named for its curved, banana-like shape, it represents the pinnacle of residential luxury in sub-Saharan Africa.

From "Lagoon City" to a Banana-Shaped Island

The original Banana Island project, then named "Lagoon City," was the brainchild of the late Chief Adebayo Adeleke, a University of London-trained civil engineer and CEO of City Property Development Ltd. After an earlier Adeleke development at Maroko, Victoria Island, was taken over by the Lagos State government following a decade-long court battle, the state offered him other parcels of land as compensation. In 1981, Adeleke began exploring the idea of generating public revenue and creating jobs by reclaiming land along the Lagos Lagoon foreshore; official approval followed in February 1983, and the British firm Westminster Dredging (Nigeria) Limited was engaged as consultant and contractor for the reclamation works.

A Project That Became a Symbol of Luxury

Chief Adeleke had originally planned to create six interlinked, symmetrical islands, but the reclamation work ultimately produced a single island with a curved, banana-shaped silhouette, giving it its final name. In the late 1980s, the Lagos State government partnered with City Property Development Ltd, owned by the Lebanese-Nigerian Chagoury Group, to continue reclaiming land along the Ikoyi coastline. This methodical, decades-long land reclamation process turned a simple foreshore dredging project into sub-Saharan Africa's single most exclusive and expensive residential address.

Strictly Controlled Access

Administratively part of Ikoyi within Eti-Osa LGA, Banana Island today enforces round-the-clock access control through private security checkpoints, backed by underground electrical networks, independent water treatment stations, and a marina reserved for residents. The contemporary architect-designed villas lining its avenues frequently come with their own private yacht mooring, a level of luxury that sums up the island's position as Nigeria's undisputed benchmark for high-end real estate, well ahead of the city's other exclusive residential enclaves.

World-Class Facilities

Underground power lines eliminate the overhead cabling seen elsewhere in Lagos, while private water treatment plants and dedicated waste management keep the island running independently of the wider city's frequently strained public utilities. Combined with a private marina where residents can dock personal boats and yachts, these systems allow Banana Island to function almost as a self-contained enclave, insulated from many of the infrastructure challenges faced across the rest of the metropolis.

Administrative context

This neighbourhood is part of the Eti-Osa LGA, which covers 299.1 km² and had 287,785 inhabitants at the 2006 census (2022 estimate: 420,100). These figures cover the whole LGA, not the neighbourhood alone, and the 2006 census is disputed. See the Eti-Osa LGA page and Wikipedia.
