Create a Kitchen That Works Better for Everyday Life
A kitchen extension can completely change the way the ground floor of your home works.
For many families, the kitchen has become much more than a place to cook. It is where people eat, work, talk, entertain and spend much of the day.
At Tholos Architects, we design kitchen extensions around the way you want to use the space, not simply around adding extra square metres.
A kitchen extension can help you:
- Create a larger kitchen
- Add a kitchen island
- Create a dining area
- Improve natural light
- Add family seating
- Improve storage
- Create a utility area
- Strengthen the connection to the garden
- Improve circulation
- Reorganise the existing ground floor
- Create a more social living space
The aim is to create a kitchen that feels naturally connected to the rest of the home.
Kitchen Extensions explained
What Is a Kitchen Extension?
A kitchen extension increases the space available around the existing kitchen or creates the opportunity to relocate the kitchen completely.
It may take the form of:
- A rear extension
- A side extension
- A side-return extension
- A wraparound extension
- A single-storey extension
- An extension combined with internal reconfiguration
The right approach depends on the existing house, available space and how much change is needed.
In some homes, a relatively modest extension can be enough.
In others, the best result comes from combining the extension with major changes to the ground-floor layout.
Why Extend the Kitchen?
Older properties often have kitchens that were never designed to be the main social space in the home.
Common problems include:
- Narrow layouts
- Limited worktop space
- Poor storage
- Small dining areas
- Weak garden connections
- Limited natural light
- Awkward circulation
- Kitchens separated from family spaces
A kitchen extension can address several of these issues at the same time.
It can create more room, but just as importantly, it can allow the whole layout to be reconsidered.
Kitchen Extensions
Create a Larger Kitchen-diner
One of the most popular outcomes of a kitchen extension is a larger combined kitchen-dining space.
This may allow you to include:
- A kitchen island
- Full-height storage
- Larger dining table
- Family seating
- Integrated appliances
- Utility space
- Better garden access
- More generous circulation
The design should make sure each area has enough room to function comfortably.
A large room is not automatically a good room.
The proportions, layout and movement between zones matter just as much as the total floor area.
Kitchen Islands
A kitchen island is often one of the main reasons homeowners want to extend.
An island can provide:
- Additional worktop space
- Storage
- Seating
- Cooking space
- Preparation space
- A social focal point
However, an island only works well if there is enough circulation around it.
The design needs to consider:
- Distance from kitchen units
- Door positions
- Dining furniture
- Access to the garden
- Appliance locations
- Movement through the room
It is better to design the room around the way the island will actually be used rather than forcing an oversized island into the space.
Kitchen Extensions
Rear Kitchen Extensions
A rear kitchen extension can increase the depth of the ground floor and create more room towards the garden.
This can work particularly well where the existing kitchen is too small or disconnected from outdoor space.
A rear extension may help create:
- A larger kitchen
- Kitchen-dining space
- Family room
- Utility area
- Garden-facing seating
- Larger rear doors
- Better natural light
The extension depth should be carefully considered so that the new space does not make the existing house unnecessarily dark.
Side-return Kitchen Extensions
In many Victorian and Edwardian homes, the kitchen sits beside a narrow side return.
Building into this space can make the kitchen significantly wider.
This can create room for:
- An island
- Larger dining space
- Better storage
- Wider circulation
- Improved garden access
- More generous glazing
Even where the additional floor area is relatively modest, widening the kitchen can make a major difference.
Wraparound Kitchen Extensions
Where more space is needed, a wraparound extension can combine side and rear extensions.
This can create a much larger footprint for:
- Kitchen
- Dining
- Family living
- Utility space
- Storage
A wraparound extension can also provide more freedom to completely reorganise the ground floor.
Open Plan or Semi-open Kitchen?
A kitchen extension does not have to create a completely open-plan ground floor.
Some households prefer one large connected space.
Others benefit from keeping some separation between:
- Kitchen
- Dining
- Living
- Utility space
- Storage
Possible approaches include:
- Fully open plan
- Semi-open plan
- Sliding doors
- Pocket doors
- Glazed partitions
- Defined zones
- Separate front reception rooms
The right arrangement depends on how you live.
Kitchen Extensions
Connecting the Kitchen to the Garden
A kitchen extension often creates the opportunity to improve the connection between the house and garden.
This may involve:
- Sliding doors
- Bifold doors
- French doors
- Large fixed glazing
- Picture windows
- Combined door and window systems
The best solution depends on:
- Views
- Furniture placement
- Privacy
- Heat loss
- Solar gain
- Budget
- How often the doors will be used
The connection should feel natural rather than simply adding as much glazing as possible.
Utility Rooms and Storage
Extending the kitchen can create the chance to improve practical storage as well.
This may include:
- Utility room
- Pantry
- Full-height cabinetry
- Laundry space
- Cleaning storage
- Boiler cupboard
- General household storage
These spaces can make a major difference to how uncluttered the main kitchen feels.
Kitchen Extensions
Kitchen Layout Planning
The architectural layout and kitchen design should be developed together.
Important decisions include:
- Where the kitchen sits
- Where appliances are positioned
- How much storage is needed
- Where the island goes
- Where the dining table sits
- How people move through the room
- Where doors open
- How the garden is accessed
- Where natural light enters
Resolving these relationships early helps avoid compromises later
Structural Changes
Kitchen extensions often involve structural work.
This may include:
- Removing external walls
- Enlarging openings
- Removing internal walls
- Installing steel beams
- Supporting upper floors
- Creating new foundations
- Forming new roof structures
If the aim is to create a large open kitchen-diner, several existing walls may need to be altered.
Drainage and Kitchen Extensions
Kitchen extensions can affect drainage because sinks, dishwashers and utility areas need suitable connections.
The project may also interact with existing drains in the garden or side return.
Considerations may include:
- Existing drainage routes
- Inspection chambers
- Shared drains
- New waste connections
- Kitchen waste
- Utility drainage
- Rainwater drainage
These need to be considered before construction.

Do Kitchen Extensions Need Planning Permission?
Not always.
Some kitchen extensions may fall within permitted development rights.
Whether this applies depends on:
- Extension size
- Height
- Depth
- Position
- Property type
- Previous additions
- Conservation status
- Local restrictions
Where permitted development does not apply, a planning application may be required.
Planning Permission for Kitchen Extensions
Where planning permission is required, the local authority may consider:
- Size
- Scale
- External design
- Materials
- Impact on neighbours
- Privacy
- Garden space
- Relationship with the original house
The design should respond to these points from the beginning.
Building Regulations for Kitchen Extensions
Kitchen extensions need to comply with Building Regulations.
Requirements may cover:
- Foundations
- Structural safety
- Insulation
- Ventilation
- Fire safety
- Drainage
- Electrical work
- Glazing
- Thermal performance
- Roof construction
Kitchen ventilation and electrical requirements also need to be considered alongside the wider extension design.

Kitchen Extension vs Internal Reconfiguration
Not every small kitchen necessarily needs an extension.
Sometimes the existing ground floor contains enough space but is poorly arranged.
Internal changes may make it possible to:
- Move the kitchen
- Remove walls
- Combine rooms
- Improve circulation
- Create better storage
- Use underused rooms more effectively
In other cases, the best solution combines reconfiguration with an extension.

Frequently Asked Questions
How big should a kitchen extension be?
There is no standard size.
The right amount of space depends on what the existing kitchen lacks and what you want the new room to include.
Can I create a kitchen, dining and living space together?
Yes.
Many kitchen extensions are designed as larger multifunctional spaces, although a fully open-plan layout is not always necessary.
Will extending the kitchen make the house darker?
It can if daylight is not planned properly.
Rooflights, larger openings and carefully positioned glazing can help bring light deeper into the home.
Can you design the kitchen layout as part of the extension?
Yes.
The kitchen position, island, circulation, storage and furniture should all be considered alongside the architectural design.
Create a Kitchen That Changes the Way You Use Your Home
A kitchen extension can provide more space, but its real value comes from creating a better relationship between cooking, dining, family life and the garden.
At Tholos Architects, we can help you explore the extension options, develop the layout and prepare the drawings required to take the project forward.
