Two Different Approvals - Why It Matters
Most people get confused about planning permission and building regulations because they sound like the same thing. They're not. Planning permission is about what you can build and where. Building regulations are about how you build it safely.
You might need planning permission, building regulations approval, both, or sometimes neither. Getting this wrong costs time and money - we've seen families have to demolish work that didn't have proper approval.
The key thing is finding out what you need before you start, not after you've already begun digging foundations.
Understanding the Two Different Systems
Planning Permission: What and Where You Can Build
Planning permission controls the size, position, and appearance of your extension. It's about protecting your neighbours, preserving the character of the area, and making sure developments are appropriate for their location.
Nottingham City Council decides planning applications based on local planning policies. Some areas have special restrictions - conservation areas like The Park, or areas with particular character they want to protect.
The good news is that many kitchen extensions don't need planning permission at all, thanks to something called "permitted development rights."
Building Regulations: How You Build Safely
Building regulations are about structural safety, fire safety, insulation, drainage - all the technical stuff that makes buildings safe and energy efficient.
Nearly every kitchen extension needs building regulations approval, even if it doesn't need planning permission. This isn't bureaucracy - it's about making sure your extension won't fall down, flood, or burn down.
Building Control fees are typically £500-1200 for a kitchen extension, depending on size and complexity. Much cheaper than rebuilding work that doesn't comply.
When You Need Planning Permission
Permitted Development Limits
Most single-storey rear extensions fall under "permitted development" and don't need planning permission. But there are specific limits you can't exceed.
For terraced houses (and Nottingham's full of them), you can extend up to 6 metres from the back of the original house. For semi-detached and detached houses, it's 8 metres.
Height limits are 4 metres maximum, or 3 metres if the extension is within 2 metres of a boundary. And you can't cover more than half your original garden area.
The family on Radford Road thought their 7-metre extension on a terraced house would be fine. It wasn't. Terraced houses have a 6-metre limit, no exceptions. They needed full planning permission, which added 3 months to their project.
Situations That Always Need Planning Permission
Two-Storey Extensions: Always need planning permission, regardless of size. No exceptions.
Side Return Extensions: These are popular in Victorian terraces for creating larger kitchens, but they usually need planning permission even if they're single storey.
Extensions That Change the Front or Roof: Any extension visible from the street, or that changes the roof line, needs planning permission.
Conservation Areas: The Park, Lace Market, and other conservation areas in Nottingham have removed or restricted permitted development rights. Most extensions need planning permission.
Listed Buildings: Any internal or external changes to listed buildings need listed building consent, which is separate from and additional to planning permission.
The Neighbour Consultation Process
Even for permitted development, larger extensions need neighbour consultation. This applies to single-storey extensions over 3 metres deep for terraced houses, or 6 metres for semi-detached houses.
You serve formal notice on your immediate neighbours, and they have 21 days to object. If they object, the council decides whether to allow the extension under permitted development or require a full planning application.
The Wilson family in Carlton went through this process for their 5-metre extension. One neighbour objected about loss of light to their conservatory. The council's planning officer visited, assessed the impact, and decided the extension was acceptable. Added 6 weeks to the timeline, but much quicker than full planning permission.
The Planning Application Process
Pre-Application Advice
For complex extensions or sensitive locations, pre-application advice costs £150 but often saves much more. You submit outline proposals and get feedback from the planning team before spending money on detailed drawings.
We always recommend this for extensions in conservation areas, near listed buildings, or where there might be neighbour issues. Better to discover problems early than submit an application that gets refused.
The family near Nottingham Castle wanted a large single-storey extension in the conservation area. Pre-application advice revealed concerns about the impact on the historic setting. We redesigned with traditional materials and lower roof lines. Full application approved first time.
Application Requirements
Planning applications need proper drawings, not sketches. You'll need:
- Existing and proposed floor plans
- Elevations showing all sides of the extension
- Site location plan showing the property boundaries
- Design and access statement for larger extensions
The drawings must be to scale and show key dimensions. For kitchen extensions, you usually need to show the relationship to neighbouring properties and how the extension might affect their amenities.
We work with a local architect who knows Nottingham's planning requirements inside out. His drawings get approved because he understands what the planning team need to see.
The 8-Week Determination Period
Standard householder applications should be determined within 8 weeks. In practice, straightforward applications often get decided quicker, while complex ones can take longer.
If neighbours object, or if the application needs committee consideration, it can extend beyond 8 weeks. Applications in conservation areas sometimes need extra consultation time.
The Thompson family in West Bridgford submitted in March and got approval in 5 weeks. Simple rear extension, no objections, and clear drawings that showed everything the planning team needed.
Dealing with Objections
Not every neighbour's objection is reasonable, but some raise genuine planning concerns. Loss of light, loss of privacy, visual impact, impact on parking - these are material planning considerations.
Good design can often address concerns. Lower roof heights, different window positions, or using materials that match the existing house can resolve many issues.
The family on Forest Road faced objections about their proposed extension being too dominant. Working with the architect, we reduced the ridge height by 600mm and used reclaimed brick to match the original house. Objections were withdrawn and permission granted.
Building Regulations - Nearly Always Required
What Building Regulations Cover
Building regulations apply to almost every kitchen extension, regardless of whether planning permission is needed. They cover:
- Structural safety of foundations, walls, and roof
- Insulation and energy efficiency standards
- Drainage and waste water connections
- Electrical installation safety
- Fire safety and means of escape
- Accessibility and disabled access
The Building Control Process
You submit plans to Building Control before starting work. They check the proposals comply with regulations and approve them (or ask for changes).
During construction, Building Control inspect the work at key stages:
- Foundation inspection before concrete is poured
- Damp course and insulation inspection
- Drainage inspection before backfilling
- Final inspection before completion certificate
Book inspections at least 2 days in advance. If they can't inspect when you need them, work stops until they can.
Structural Calculations
Most kitchen extensions need structural calculations for foundations and any new openings between the extension and existing house. You can't guess these - Building Control wants proper engineer's calculations.
We work with a structural engineer who knows Nottingham's ground conditions and typical house construction. His calculations get approved quickly because Building Control knows and trusts his work.
The Victorian terrace in Sherwood needed special foundations because of clay soil movement. Standard foundations would have cracked within a year. The structural engineer designed deeper foundations with flexible connections. More expensive initially, but no problems 5 years later.
Nottingham-Specific Planning Considerations
Conservation Areas
Large parts of Nottingham are designated conservation areas: The Park, Lace Market, parts of Sherwood, and many others. Each has a specific character that planning policy aims to preserve.
In conservation areas:
- Permitted development rights are more restricted
- Materials and design details matter much more
- Traditional appearance is usually required
- Even internal changes might need consent in some cases
The family in The Park wanted a contemporary glass extension. In a conservation area, that wasn't appropriate. We redesigned using traditional proportions with larger windows for light, but keeping the overall character compatible with the Victorian surroundings.
Archaeological Considerations
Parts of Nottingham have archaeological significance, particularly near the medieval city centre. Extensions requiring deep foundations might need archaeological investigation.
This sounds dramatic, but it's usually just an archaeologist watching during excavation. Only delays occur if significant finds are discovered, which is rare for domestic extensions.
Listed Buildings
Some Nottingham properties are individually listed as well as being in conservation areas. Listed building consent is required for any alterations, internal or external.
Listed building applications take longer (8 weeks minimum) and cost more, but approval is possible with good design that respects the building's character.
The Grade II listed house near Nottingham Castle needed extensive structural work to create a modern kitchen. Listed building consent was granted because the work secured the long-term preservation of the building while making it usable for a modern family.
Drainage and Flood Risk
Parts of Nottingham near the River Trent are in flood risk areas. This affects foundation design and might require sustainable drainage for new roof areas.
Surface water from extensions often needs to connect to existing drains or soak away naturally. Building Control wants to see how this will be managed.
Tree Preservation Orders
Many Nottingham streets have Tree Preservation Orders protecting significant trees. Extensions that might affect tree roots need careful consideration.
The family on Derby Road wanted to extend close to a protected oak tree. We had to demonstrate that the foundations wouldn't damage the root system and include protective measures during construction.
Common Mistakes That Cost Money
Starting Work Before Approvals
Never start construction before getting all necessary approvals. If Building Control or planning officers require changes, you might have to demolish completed work.
The family in Arnold started digging foundations while their building regulations application was still being processed. When Building Control required deeper foundations due to ground conditions, they had to start again. Cost an extra £2000 and 3 weeks delay.
Assuming Permitted Development Applies
Don't assume your extension falls under permitted development without checking thoroughly. Previous extensions, conservation areas, planning conditions, and other factors can remove or restrict these rights.
The house in Mapperley had a small 1980s extension that used up some of their permitted development allowance. The new 4-metre extension put them over the limit and needed full planning permission. Added 3 months to the timeline because they hadn't checked first.
Poor Quality Applications
Cheap drawings often mean refused applications. Planning officers need to see clearly what you're proposing and how it affects neighbours and the surrounding area.
Professional drawings cost £800-2000 for a typical kitchen extension, but refused applications cost much more in delays and resubmission fees.
Ignoring Neighbour Concerns Early
Talk to neighbours before submitting applications. Many concerns can be addressed through design changes, avoiding formal objections that delay the process.
The family on Lenton Road met with all their neighbours before applying. They adjusted window positions to address privacy concerns and agreed on screening plants for the boundary. No objections, smooth approval process.
Not Understanding Building Regulations
Building regulations are technical and detailed. DIY applications often miss requirements that cause delays during construction. Professional help usually pays for itself.
Working with Nottingham City Council
Planning Team Relationships
We've built good relationships with Nottingham's planning team over 15 years. They're generally helpful and want to approve applications that comply with policy.
Pre-application discussions are invaluable. Planning officers can identify potential problems early and suggest solutions before you invest in detailed drawings.
Building Control Efficiency
Nottingham's Building Control team are thorough but pragmatic. They understand local construction methods and typical ground conditions.
Response times are usually good - plan checking within 5 weeks, inspection visits within 2-3 days of booking. Much more responsive than some neighbouring authorities.
Conservation Area Guidance
The conservation team provide helpful guidance on appropriate materials and design approaches for different conservation areas. They understand that historic buildings need to work for modern families.
Good communication early in the process prevents problems later. They're much more helpful if you involve them in design development rather than presenting them with a finished scheme.
Timeline Planning
Realistic Timescales
- Planning permission (if needed): 8 weeks minimum
- Building regulations approval: 5 weeks for plan checking
- Listed building consent: 8 weeks minimum, often longer
- Building work: 4-6 weeks for typical single-storey extension
Build these timelines into your project planning. Starting design work in January for a summer build gives time for any complications.
Seasonal Considerations
Planning applications can be submitted any time, but construction timing matters. Concrete work can't happen in freezing conditions. Roof work is weather-dependent.
Most families prefer summer construction to minimise disruption to family routines and reduce heating costs while the house is opened up.
Getting It Right First Time
Planning permission and building regulations might seem complicated, but they exist for good reasons. Following proper procedures protects you, your neighbours, and ensures your extension is built safely.
We've guided dozens of Nottingham families through these processes. With proper planning, realistic timelines, and professional help where needed, you can navigate the requirements successfully.
The key is understanding what approvals you need before you start, not discovering problems halfway through construction. A few weeks extra planning saves months of delays and thousands in remedial work.
Your kitchen extension should enhance your home and family life. Getting the approvals right the first time means you can focus on creating the space you want, not fighting bureaucracy.
