The project consists of an organic skin which, in one single gesture, becomes the roof and external walls of the Church, enveloping and protecting the Congregation within. The main access is placed in the narrowest and lowest part of the building and leads into a spectacular entrance foyer, from which the visitor has views and clear access to both floors of the Church. The main staircase in the entrance foyer divides the Church into two halves which are visually linked by the large atrium that traverses the building. The funnel effect within the entrance foyer moreover reinforces the huge and spectacular scale of the main Congregation Hall and the Chapel of Perpetual Adoration to either side.
The architectural concept and structural form are integral, with a series of arches of varying heights producing the sculptural form of the building as a whole. Arches are one of the oldest and most efficient forms of structure, utilizing the full height of the building to provide stiffness resulting in a relatively slender structure. Fabricated steel arches are positioned at 4m centres along the length of the building, with cold-formed steel purlins spanning between the arches supporting the roof finishes and ceiling within. These arches are supported on each side of the building by a series of piled foundations taking vertical loads into the ground beneath. The horizontal thrust which results from the arching action is resisted by a reinforced concrete ground slab which ties the two bases of the arch together.
The main spaces for prayer have been designed to be peaceful, awe inspiring, and full of joy whilst also allowing the worshippers full and uninterrupted views of the Altar. The impressive glazed facades on both the East and western axis of the Church provide natural lighting and emphasize the height and scale of both areas of worship. The interior of the Church is very simple, pure and full of spirituality. The outside is elegant, timeless and will stand as a true Icon for the Catholic community of Lagos and Nigeria as a whole.
