What Counts as a Residential Alteration vs an Extension?

An alteration works within your home's existing footprint. Common examples include removing internal walls, reconfiguring bedroom and bathroom layouts, converting a garage into living space, or upgrading a roof structure. An extension adds new floor area beyond the current envelope. Both improve liveability and value, but they follow different consent pathways. CBA Design can help you identify which applies from the very first consultation.

How Does the Auckland Consent Process Work for Alterations?

Building consent is required for most structural and significant alterations, including internal wall removal, roof alterations, and wet area reconfigurations. CBA Design manages the entire process on your behalf, from assessing your project against the Auckland Unitary Plan through to preparing and lodging all drawings, specifications, and supporting documentation with Auckland Council. The team is experienced in identifying when resource consent may also be needed, which can be relevant in established suburbs like Parnell and Devonport where heritage overlays apply.
