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.
| 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 |

Check your planning routeWhy January is the Best Time to Start Planning
Starting your extension planning in January offers several advantages:
- Beat the spring rush: Most homeowners wait until spring to start thinking about extensions, meaning designers and builders get booked up quickly. By starting now, you'll have your pick of the best professionals.
- Allow time for decisions: Application routes and authority decision times vary. Do not assume a January start will result in permission or a construction start by a particular season.
- Make the most of summer: Imagine enjoying your new kitchen-diner for summer barbecues and family gatherings.
- Fresh start mindset: The new year brings motivation and energy - channel that into creating your dream home.
