Hampshire Build's 95% Planning Approval Rate

Quick answer

Whether a project needs planning permission depends on its design, permitted development rights and property-specific restrictions. Building Regulations are a separate requirement even where no planning application is needed.

Key Takeaway

Our architectural design approach, 95% planning approval rate and 20+ years of experience, with an address-specific planning check before committing.

How do project costs and planning routes compare?

Extensions add to the building, while loft and garage conversions work with existing space; each has different structural and planning considerations. The route depends on the property, so these comparisons are not an individual planning decision or quotation.

Single-storey, two-storey, loft and garage projects: planning, cost factors and design route
Project Typically needs planning? Main cost factors Typical design route
Single-storey extension May qualify for permitted development if all conditions apply Footprint, foundations and specification Survey, layout, planning check and technical drawings
Two-storey extension Depends on the design and permitted development limits Structure, roof design and specification Survey, planning check and coordinated structural information
Loft conversion Some roof works may qualify, subject to restrictions Roof type, stairs and structural work Roof and layout assessment, planning check and Building Regulations
Garage conversion Often possible without a planning application, but exceptions apply Insulation, structure and services Survey, planning check and Building Regulations design
