Retrospective Green Belt Planning Permission Outbuilding Halifax Calderdale Council

At HEAL Planning, we recently secured retrospective planning permission for an outbuilding at a semi-detached property in Halifax, West Yorkshire. The case presented several challenges: the site lies on a steep slope within the designated Green Belt, and permitted development rights had been removed under a previous planning decision. The outbuilding had already been built and was intended as a home office and garden room, but the lack of planning consent was preventing the property sale from proceeding.

Following our free consultation and detailed assessment, we advised that a carefully prepared retrospective planning application could succeed despite the restrictions. We prepared a comprehensive planning statement that demonstrated compliance with national and local policy. Our argument was built on two key exceptions under the National Planning Policy Framework: the outbuilding could be classed as an extension to the main dwelling, and it also qualified as a replacement for dilapidated outbuildings that were previously on the site. We supported this with photographs, aerial imagery, and case law to show a reduction in overall built volume and an improvement to the site’s character.

Calderdale Council approved the application on the 8th of August, with only minimal conditions attached. This outcome highlights the value of expert planning guidance, particularly for retrospective applications in sensitive locations such as the Green Belt. At HEAL Planning, we combine technical expertise, policy knowledge, and strong evidence-based arguments to unlock successful outcomes, even in cases where clients fear refusal is inevitable. Whether you need help with a new or retrospective application, our team is here to guide you through every stage of the process.
