Self-Contained Annexe
Design Proposal
The scheme comprised a single-storey ancillary annexe, carefully designed to remain subservient to the main dwelling and fully compliant with both local and national planning policy.
The annexe provided self-contained accommodation while retaining clear ancillary status, with no ability to function as a separate dwelling.
The internal layout included:
Bedroom
Shower room
Kitchenette and living space
The total footprint was kept deliberately modest to minimise visual impact and preserve the character of the surrounding residential area.
Materials & Appearance
The annexe was designed to integrate sympathetically with its surroundings while maintaining a contemporary finish, including:
Masonry brickwork to complement nearby properties
Anthracite grey windows and doors
Flat roof construction with a durable membrane finish
Affordable Architectural were instructed to provide a planning-led design and feasibility service for a proposed ancillary residential annexe within the curtilage of an existing dwelling in Wednesbury, West Midlands.
The proposal was submitted and approved through planning under a Householder Planning Application.
These drawings are redacted so some information may be missing.
Planning Considerations
Key planning principles addressed within the design and application included:
Ancillary use only, remaining part of the same planning unit as the main dwelling
No separate access, postal address, or utility connections
Careful siting within the rear garden to avoid overlooking and loss of neighbour amenity
Retention of the majority of existing garden space and boundary treatments
No increase in parking demand, supported by existing on-site provision and shared parking nearby
The proposal was assessed against the National Planning Policy Framework (NPPF) and relevant local development plan policies, with the scale, appearance, and function considered appropriate for approval.
Outcome
The project successfully achieved planning approval, providing a compliant and practical solution for intergenerational living without altering the character of the area or creating planning risk.
