Planning for oak buildings
Understand where you stand on permitted development, full planning, boundaries and the application process, then let Southern Oak coordinate the rest.
Guidance on this page summarises the national rules for England. Different rules apply in Wales and Scotland, and local planning conditions, Article 4 directions and property-specific restrictions may apply. This is general information, not a formal planning determination. Confirm the position with the relevant local planning authority or building control body before starting work.

How the appraisal worksPlanning FAQ
Common planning questions
Many oak garages, garden rooms and other outbuildings can fall within permitted development if they meet the relevant siting, height, coverage and use conditions. Full planning may be needed where those limits are exceeded, permitted-development rights have been removed or restricted, the property is affected by listed-building or designated-land rules, or the proposal is for self-contained living accommodation. Green Belt designation does not by itself automatically remove householder permitted-development rights.
Permitted development lets you build certain outbuildings and extensions without a planning application, subject to size, height, siting and use limits. Full planning permission is a formal application to your local authority with drawings, consultation and a decision notice. We handle both routes and advise which applies to your project.
A householder planning application is usually decided within eight weeks of validation, although the target can be extended and more complex cases can take longer. A project that is genuinely permitted development does not require a full planning decision, but the property-specific rights and restrictions should still be checked before work starts. A Lawful Development Certificate can be used where formal confirmation is wanted.
Southern Oak coordinates its planning service with Planning By Design, covering feasibility, drawings, applications, building regulations and related professional input where included in the agreed quotation. Responsibilities and fees are confirmed in your quotation, so you know what is included before work begins.
The appraisal costs £250 + VAT. The fee becomes non-refundable once work begins but will be credited against the cost of a full planning application if you proceed through Southern Oak. It flags planning risk early so you can decide before investing in drawings.
