4D Planning advised the client on the potential to extend the property to create additional habitable space. We advised the client to apply for Prior Approval for a large 6m deep extension to the rear of the ground floor and to apply separately for a lawful development application for the roof extension, loft conversion with rear dormer and rooflights. 4D Planning prepared the architectural drawings for each application and obtained Havering Council's approval for both applications. 4D Planning was then instructed to prepare the Building Regulations to satisfy Building Control and to liaise with the Structural Engineer. We also produced the Tender Pack for the builders.
Navigating the complexities of Havering Planning can be challenging, especially when proposing extensive property alterations. At 4D Planning, we secured approval for a project involving a hip to gable roof extension with rear dormer, a single-storey 6m rear extension, and rooflights. This project also required compliance with Building Regulations for single storey extensions and roof extensions.
The following paragraphs will explore the planning and regulatory steps involved, including obtaining a Havering Lawful Development Certificate, ensuring compliance with Building Regulations, and achieving approval for these ambitious improvements.
The project included:
By combining a roof extension with a rear dormer and a single-storey rear extension, the property owners aimed to significantly enhance both the interior space and overall aesthetic of their home and increase the value of the house.
In many cases, property owners can carry out specific types of work without requiring full planning permission, thanks to permitted development rights. For this project, the hip to gable roof extension with rear dormer fell under these rights, meaning it did not require planning permission.
However, to confirm the legality of the proposed works and avoid potential disputes, we applied for a Havering Lawful Development Certificate.
The certificate serves as official confirmation from the council that your project complies with permitted development rules. It is especially important for projects like roof extensions, where the regulations around height, volume, and design can be complex. Having this certificate also provides reassurance for future property sales, as it confirms the work was lawfully executed.
Although the 6m single storey rear extension might be eligible for permitted development, it exceeded the standard 3m or 4m limit for semi-detached and detached properties. This made it necessary to apply for prior approval from Havering Council.
Our team prepared a comprehensive application, including:
By addressing these factors, we were able to secure approval from Havering Council for the extension.
Beyond planning approval, all projects must comply with Building Regulations to ensure structural safety, energy efficiency, and fire safety. For this project, we worked closely with our clients to ensure:
Our expert understanding of both planning and building regulations helped streamline the process and avoid delays.
Installing rooflights as part of a roof extension under permitted development required careful placement to maximise light while maintaining compliance with regulations.
For the single storey extension, we addressed neighbours’ concerns about overshadowing and ensured the design minimised any adverse impact. By engaging early and transparently, we avoided objections and delays.
At 4D Planning, we specialise in guiding property owners through complex planning processes, from Havering Lawful Development Certificates to single storey extensions approved by Havering Council. Here’s why we stand out:
