An architecture firm working across all types of projects, AD Architecte draws on extensive experience in rehabilitation and major renovation projects carried out in occupied buildings, both in the residential sector and in public-access buildings.
The firm has developed recognised expertise in the education sector, with numerous projects involving the renovation, upgrading and transformation of schools and educational facilities. This experience enables the team to effectively address the specific challenges associated with working in occupied buildings and to implement an organisation tailored to the requirements of each site.
Aware of the particular constraints associated with educational facilities, AD Architecte has also adapted its organisation to ensure an increased presence during July and August, a key period for carrying out works while minimising their impact on the day-to-day operation of the establishments.
The firm therefore supports its clients with an approach based on availability, rigour and careful management of technical and organisational constraints, ensuring the successful delivery of projects from design through to completion.
