Cornerstone Tower

Cornerstone Tower

Situated on Victoria Island, the rapidly growing business and finance hub of Lagos, Cornerstone Tower is a grade-A office building with state-of-the-art finishes. Conveniently located near public transportation, tenants of the tower have easy access to mainland Lagos, Lekki and Ikoyi. The building provides an environment that is not only comfortable, but also resource-efficient. Combining advanced technology with modern and functional design, Cornerstone Tower meets the needs of contemporary businesses.

Developed by African Capital Alliance (ACA) and Cornerstone Insurance, and designed by Delano Architects, Cornerstone Tower was constructed with green features to ensure the conservation of natural resources. The tower has higher thermal performance glass, energy-efficient air conditioning and motion sensor lights to reduce energy use. It is also expected to conserve water by more than 50 percent with the help of water-efficient fixtures. Tenants of the 12-floor office building are expected to see their utility bills reduced nearly in half because of these resource-efficient features.

ACA, a leading investment firm in Sub-Saharan Africa, is passionate about contributing to the sustainable development of Lagos by building green. The firm developed Cornerstone Tower with the help of Cornerstone Insurance, which has provided insurance to Nigerian customers for over 20 years and occupies two floors of the tower. Cornerstone Tower has received a preliminary EDGE certificate from thinkstep-SGS.
