AP Valletta is a research-based architecture and design firm located in Malta. Our collaborative, multidisciplinary team of architects and thinkers intertwine sustainable adaptive reuse strategies with traditional architectural services, working on a vast range of projects. Over the last 30 years, the firm has widened its expertise on projects of varying scale and complexity, in Malta and overseas, and it has been particularly successful in the development of projects located within historical environments, often carried out in collaboration with other partners and specialists. A significant reflection of our work is evident in our relationship with the city of Valletta. AP has contributed to its regeneration, challenging the status quo in the perception and preservation of local heritage and initiating debates both locally and internationally, engaging with experts and emphasizing the social and economic importance of testing innovative and sustainable design approaches.
