25 Montpelier Road Commercial Development employed rigorous architectural testing and 3-D computer modelling to resolve complex issues of building form and scale, as well as functional and environmental performance. Building mass and orientation were determined through analysis of existing site conditions and controlled in order to maintain view corridors to the Brisbane CBD from neighbouring sites. Split level basements and structural terracing were employed to manage a steep and complex site.
Integrated green space takes the form of a rooftop garden terrace which provides outdoor amenity for office tenants and contributes to the management of building height limits. Sun path analysis, supported by the 3-D modelling process, determined facade articulation including vertical and horizontal sun shading devices. These are arranged to achieve minimal heat gain whilst contributing to the characteristic visual rhythm of the facade.
25 Montpelier Road was the first building in Queensland to achieve an approved 4-star Green Star rating and 4.5 Nabers rating on initial submission.
