These are buildings whose function is closely linked to the gathering of large numbers of people. TPA sees these buildings as sharing common characteristics: the need to create functional and comfortable spaces for the projected number of visitors which can be altered according to a specific purpose, while at the same time being accessible and having open areas and car parks. While the commercial character of these buildings can be significant, the design work of TPA aims to appropriately highlight the buildings themselves and to create a pleasant and conducive environment to spend time in.
