House Extension Planning Applications

House extension planning applications cover a wide range of different skills and challenges.

The location and planning context of the house extension project is critical. We have been involved with projects in the Green Belt, Conservation Areas, requiring Listed Building Consent, corner plots, in open Countryside, Permitted Development, Prior Approval among many others.

In additional we have undertaken many planning appeals for house extensions where planning permission has been refused for many different reasons.

Many Local Athorities (including places like Trafford and Warrington) have very prescriptive house extension supplementary planning guidance which can often be quite restrictive, especially when considering larger house extension or home remodelling projects.

Please contact us to discuss your particular project and we can provide a tailored project experience to you.

House Extension

The following case studies provide a small sample of interesting and challenging different types of house extension applications we have been involved with.

House Extensions Stafford

House Extensions to large Period Arts & Crafts Manor House in open countryside, Stafford, Staffordshire

We were appointed to take a holistic view of the substantial detached property, located in open countryside which had received numerous house extensions throughout its life. The property, dating back several hundred years, originally started life as a modest two storey cottage.

Several subsequent extensions had been added, ultimately creating a substantial l-shaped property without considering how the house should work as a whole. The final house extension proposals, in effect created a 83% increase in the original dwelling. This was far in excess of the 70% stated in planning policy, however we were able to justify the proposals and convince the LPA to approve the application within the statutory period.

House Extensions Trafford Planning

Planning Approval of two storey side house extension on corner plot following planning appeal refusal. Altrincham, Cheshire

Following two refused planning applications and an unsuccessful planning appeal, we were appointed to obtain planning approval for a substantial house extension to a detached house on a corner plot.

Corner plot house extension projects are often very complex due to building lines and impact on the street scenes however, we managed to secure planning permission, from Trafford Council, at the first attempt, giving the client the required amount of accommodation and additional bedrooms desired.

Green Belt House Extensions

Green Belt House Extension in Cheshire East

The detached dormer bungalow had previously been extended past the LPA’s suggested 30% local planning policy, however, our clients weren’t aware of the policies when they purchased the property and still wanted substantial green belt house extension. Following an initial review, we suggested a planning strategy not only to further extend the house but also to create complimentary outbuildings. The site was quite complex with an irregular shape and substantial level changes. The site was fairly exposed with fantastic panoramic views across Cheshire.

Ultimately we achieved approval for a green belt house extension (not including outbuildings) over 200% larger than the “existing” house but almost 300% larger than the “original” dwelling.

Flat Extension

Approval for Extension to Flat, Conservation Area, Liverpool

Situated within a Conservation Area of Liverpool, our client owned a large detached Victorian property comprising 7 apartments. The refused scheme sought to reconfigure and substantially extend the property to create a new two bedroomed apartment.

The Planning Inspectorate agreed with our argument that the proposed works would not harm the living conditions or neighbouring occupiers, would not have an overbearing or dominant impact on the outlook of neighbouring properties, would not have an adverse affect on the residential amenity and would comply with the relevant planning policy, contradicting the LPA’s reason for refusal.

In parallel with the planning appeal process, we worked with the client and LPA to redesign the refused scheme and ultimately this received planning approval. Viewing the problems as a whole we developed a two storey proposal of around 900 sq ft with two large bedrooms, two bathrooms and a large living space on the ground level. The proposed floor levels amended the original building by effectively lowering the floor to allow a new floor above, without increasing the height of the existing roof which was a crucial area of concern for the Planning and Conservation Officers. The revised scheme had several improvements from the refused scheme including a better outlook and daylighting from the main living spaces and bedrooms, a proper secure and private entrance as well as private external amenity space which was achievable within the original scheme. It is proposed that the revised scheme would create a higher value for the client whilst generally being more cost effective to construct.

House Extensions

Planning Approval contrary to SPG planning policy for house extension in Cheshire

The neighbouring property had recently received planning refused for an almost identical  (in planning terms) house extension due to the fact that it was contrary to the Council’s supplementary planning guidance. Our planning strategy successfully obtained planning permission (at the first attempt) and without amendment to the proposed house extension design.
