Garden Rooms & Home Offices
Garden offices can provide a quiet and productive environment for remote work, and our designs focus on insulation, lighting and year-round usability. We also integrate nearby garden sheds where extra storage is required.
Garden Sheds & Storage Buildings

Detached Studios & Annexes
Perfect for guest accommodation or independent living spaces, annexes require careful planning. We ensure your design meets all regulatory and structural requirements and helps you navigate the garden building approval London process efficiently.
Planning permission for outbuildings depends on several factors, including size, height and location.
In many cases, outbuildings fall under permitted development rights, meaning formal planning permission may not be required. However, restrictions apply, such as:
Our team assesses your project and determines whether permitted development applies or if a full planning application is required. We manage the entire process, ensuring compliance with local council policies across London and guiding you through every step of the outbuilding planning process UK, including sheds and smaller garden structures.
Even if planning permission isn’t required, building regulations for outbuildings still apply to ensure safety and compliance. At AA Drafting Solutions, we make sure your outbuilding meets all essential standards, including structural stability, thermal insulation, ventilation, lighting and electrical and fire safety requirements.
Our team prepares detailed building regulation drawings to streamline approval and provide clear guidance for construction. This ensures your outbuilding project is fully compliant, safe and ready to be built without delays, giving you peace of mind from design to completion.

Initial Consultation: We begin by discussing your ideas, lifestyle needs, and project goals. This helps us understand exactly what you want from your outbuilding, whether it’s a home office, garage conversion, studio, or garden annex.
Site Survey: Our team visits your property to assess the available space, topography and existing structures. This allows us to identify any challenges and provide practical solutions before design begins.
Concept Design: Based on your requirements and the site survey, we create layout options tailored to your needs. These concepts consider functionality, aesthetics and compliance with local planning and building regulations.
Planning Drawings: We prepare detailed architectural drawings that clearly show dimensions, layouts, and elevations. These plans form the foundation for council submissions and ensure every aspect of your project is accurately represented.
Application Submission: Whether your outbuilding requires permitted development approval or full planning permission, we handle the entire submission process. Our experience with London councils ensures that applications are correctly completed, reducing the risk of delays or refusals.
Approval & Next Steps: Once your application is approved, we continue to support you with any further requirements and provide guidance to prepare your project for construction.
