Here you can see a small sample of the extension projects we have designed and gained planning approval for.  


Our extension projects involve a range of application types - predominantly full planning permission (Permis de Construire or "PCMI"), but also some minor works declarations (Declaration Prealable or "DP"). All have required RE2020 thermal attestations and the majority required surveys for private drainage systems and other approvals.
