GALAXY BACKBONE

The form was inspired by the rectangular nature and slope site, the need to express interconnectivity (which is critical component of network for which the client is known for) where we have used link bridges at different levels and transparency because the client is also known for sharing and storage of data received from the public, where we have incorporated the use of large span of glazing at the façade including the use of panoramic lifts were also incorporated into the structure.

To meet setback requirements of 6 meters from the road, a 300 x 600 mm column system was adopted, extending the full height of the structure with link beams at each level. These support a triangular steel pergola at the roof level, symbolizing the connection between sky and earth. The site’s slope was also utilized to create two basement parking levels, with the lowest point forming the upper basement.

A central courtyard enhances natural ventilation through the stack effect, ensuring cross-ventilation across all spaces and reducing overall energy consumption. The façade combines 2400 x 600 mm reusable aluminum cladding in shades of grey and beige, link bridges to break the massing, curtain walls with louvers, and a recessed top floor (set back by 1800 mm) to enhance aesthetics.

Sustainable strategies include deep roof overhangs for shading, rooftop solar panels supplying energy for office functions, water pumps, lighting, and heating, and a courtyard that promotes natural ventilation and cooling. Aluminum louvers and recessed windows provide additional solar control. Green roofs over the link bridges contribute both aesthetic and thermal benefits.

Water management systems channel roof runoff to an underground storage facility for recycling. Local materials and extensive landscaping with trees and shrubs serve as noise buffers and shading elements. The design also incorporates social responsiveness, phased construction, clear circulation, and defined emergency exit routes. Hardscape materials with a solar reflectance index above 29 help moderate the urban heat island effect.

Interior partitions combine glass and Boral Plasterboard made from natural gypsum and 100% recycled paper liner. The material offers low embodied energy, non-toxic composition, and potential for reuse or recycling. It also improves indoor air quality and thermal and acoustic performance.

Zero-heat, energy-saving bulbs are specified throughout. Walls will feature POP screed for thermal comfort and VOC-free “green” paint for improved indoor air quality and ease of maintenance. Ceramic tiles are recommended for flooring due to their durability, hygiene, and non-toxic properties.

The building is oriented along the northwest–southeast axis to reduce solar exposure and maximize the southwest and northeast trade winds typical in Nigeria. This orientation also enhances street appeal and allows occupants to enjoy scenic site views.
