Planning Approval Granted – 126 Green Lane, St Albans
Introduction
MSK Design Ltd are pleased to confirm that planning permission has been granted by St Albans City and District Council for a single-storey side and rear extension, including a new front porch and raised rear terrace, at 126 Green Lane, St Albans.
The approval enables the sensitive enhancement of an existing semi-detached dwelling within a predominantly residential street, delivering improved internal accommodation while respecting the character of the surrounding area.
About the Proposal
The approved development comprises a single-storey side and rear extension, alongside a new front porch and a modest raised rear terrace. The proposal was designed to improve the functionality and usability of the home while maintaining a clear visual hierarchy between the original dwelling and the new additions.
The scale of the extensions remains subordinate to the host property and retains sufficient private amenity space and on-site parking provision.
Design and Character Considerations
The proposal was carefully designed to ensure compatibility with the host dwelling and the wider street scene. Although the extension incorporates a flat roof, the Planning Officer noted that flat-roofed elements are a common and accepted feature within the local context, and their use was therefore considered appropriate.
Materials were specified to match the existing dwelling, ensuring a cohesive appearance and a high-quality finish. The resulting development was found to sit comfortably within the established residential character of Green Lane
Planning Policy & Officer Assessment
In assessing the application, the Council considered the proposal against the St Albans District Local Plan Review 1994, relevant Supplementary Planning Guidance, and the National Planning Policy Framework (NPPF).
The Officer concluded that:
The proposal is acceptable in principle and complies with Policies 69 and 72 relating to design quality and residential extensions.
The development would not result in any harmful impact on the character and appearance of the street scene.
There would be no unacceptable loss of light, privacy or outlook to neighbouring properties.
The proposal meets adopted parking standards, with no adverse impact on highway safety.
The raised rear terrace is modest in scale and acceptable in amenity terms.
Overall, the scheme was considered to represent sustainable development, in accordance with the presumption in favour of development set out within the NPPF.
Residential Amenity and Neighbouring Impact
The Council confirmed that the proposal complies with relevant BRE daylight and sunlight guidance and does not exceed permitted depth or height thresholds along shared boundaries.
No objections were received from neighbouring occupiers, and the development was found to preserve an acceptable level of residential amenity for adjoining properties.
Outcome and Decision
Planning permission was granted under delegated authority, subject to standard conditions relating to approved plans, materials, and implementation.
The decision recognises the proposal as a well-considered residential extension that enhances the host dwelling without causing harm to neighbouring amenity or local character.
