AVI, Bryanston, Johannesburg
Due to the expansion of staff and significant growth of the company over the last 10 years, AVI required office extensions in order to provide adequate working space for staff and new company services. The extensions include open plan offices, a new canteen, auditorium and multipurpose rooms. As the building contains various independent yet interacting departments, the alterations had to allow for seamless movement between spaces.
Design and construction challenges lay within merging the new wings with the old building, and integrating the new aesthetic throughout the entire complex. The atrium of the existing building was re-designed to form the nexus between old and new – natural lighting and high volumes turn this into the heart of the complex, allowing for comfortable interaction between various users and departments.
An important factor of the brief was to rebrand the building’s aesthetic to align with the company’s values and contemporary thinking. The innovative and efficient nature of the company is manifested and captured within a new building skin, encasing the new and existing wings. This skin consists of louvres which passively control heat gain – allowing for maximum heat gain in winter and maximum shade in summer. The design of the louvers on the façade has been generated by a parametric process, which ensures that the façade responds precisely to the various sun angles along the full length of the buildings' perimeter.
In this manner, the louvers not only become an aesthetic statement of the AVI brand, but form part of an overall approach to sustainability within the development. This approach includes the use of a brownfield site, and integration of an existing building, as an important sustainability consideration. The building also makes use of rainwater tanks as an alternative water source, and has an extensive photovoltaic array on the rooftop to provide portions of the building with clean energy.
