Extensions & Conversions
Designed to unlock more space and value
Planning Design 360 provides measured, practical design support for home extensions and conversions, helping homeowners turn underused space into well-planned, compliant living areas.
What we cover
Extension and conversion services
We support projects from early feasibility through planning and drawing packages, with advice tailored to the property, site constraints, and intended use.
Rear and side extensions
Layouts and planning-ready proposals for single-storey, double-storey, wraparound, and side return extensions that improve flow, light, and usable floor area.
Loft conversions
Design development for loft rooms, dormers, and roof alterations, with careful attention to head height, stair positioning, and planning considerations.
Garage and outbuilding conversions
Conversion schemes that help transform existing structures into home offices, annexes, studios, or additional living accommodation.
Planning and drawing support
Measured drawings, proposed plans, and application-ready documentation prepared to support a smoother route through planning review and project delivery.
A clear design process
Our approach keeps the project structured from first discussion to submission-ready information.
01
Initial consultation
We discuss your goals, budget expectations, property constraints, and the type of extension or conversion you want to achieve.
02
Survey and concept design
Existing layouts are reviewed and early design options are developed to test space planning, massing, and practical feasibility.
Thoughtful planning at the design stage helps reduce delays later and gives clients greater confidence in the direction of the project.
03
Planning drawings
We prepare the drawings and supporting information needed for planning applications or pre-application discussions where appropriate.
04
Refinement and next steps
Once the preferred scheme is agreed, we help you move forward with coordinated documentation for the next phase of the project.

Planning Design 360 delivers carefully considered architectural support for home extensions, loft conversions, garage conversions, and reconfigured interiors, with a focus on clarity, proportion, and planning confidence.
