Choosing between the different types of home extensions can feel overwhelming at first. A bigger kitchen, an extra bedroom, a brighter living space or a more practical layout can all be achieved in different ways, but the right choice depends on your property, budget, garden space and long-term plans.
At Creations Building & Landscaping, we help homeowners across Reigate, Surrey and the surrounding areas create well-built home extensions, garage conversions, conservatories and loft improvements that suit the way they actually live. Our work is tailored to each home, with a focus on strong craftsmanship, practical design and finishes that feel like they have always belonged.
What Are the Main Types of Home Extensions?
The main types of home extensions include single storey extensions, rear extensions, side return extensions, wrap around extensions, double storey extensions, kitchen extensions, conservatories, orangeries, garage conversions, loft conversions and over-structure extensions. These options all create extra space, but each one works best for a different type of home and purpose.
Single Storey Extension
A single storey extension is one of the most popular choices for homeowners who want more living space without changing the upper floor of their home.
This type of extension is usually added to the rear or side of a property. It can be used for an open-plan kitchen, a larger dining area, a utility room, a playroom, a home office or a more spacious lounge. It is often a practical option for families who need more everyday space but do not necessarily need another bedroom.
A single storey extension can also bring in more natural light through roof lanterns, skylights, large windows or bi-fold doors. For many homes, this creates a better connection between the house and garden, like this home extension in Reigate.
Rear Extension
A rear extension extends the back of the property into the garden. It is a strong option when the existing kitchen or dining room feels too small, dark or disconnected from the outdoor space.
Rear extensions are often used to create:
A larger kitchen-diner
An open-plan family room
A garden-facing lounge
A utility or boot room
A brighter entertaining space
This option works particularly well when there is enough garden depth to extend without losing too much outdoor space. The key is balance. A good rear extension should improve the house while still leaving a garden that feels usable and attractive.
Side Return Extension
A side return extension uses the narrow strip of land often found at the side of Victorian, Edwardian, terraced or semi-detached homes.
This area can be easy to overlook, but it can make a big difference to the feel of the ground floor. By building into the side return, a narrow kitchen can become wider, brighter and more practical. It is a clever way to add space without extending too far into the garden.
Side return extensions are especially useful when the main issue is width rather than overall floor area. With the right glazing and layout, this type of extension can completely change how a kitchen or dining area works.
Wrap Around Extension
A wrap around extension combines a rear extension and a side return extension to create an L-shaped addition to the home.
This is a bigger project than a simple rear or side extension, but it can create a dramatic improvement. A wrap around extension is often chosen when homeowners want to remodel the entire ground floor, create a large open-plan kitchen and living area, or improve flow between rooms.
Because it changes more of the property footprint, design is especially important. The new space needs to feel open and useful without making the home feel too large at the back or reducing the garden more than necessary.
Double Storey Extension
A double storey extension adds space across two floors. It can create a larger kitchen or living area downstairs, while also adding a bedroom, bathroom or office upstairs.
This can be one of the most space-efficient types of house extensions because the same foundations and roof structure support two levels of additional space. It is often chosen by growing families who need more room but want to avoid moving.
A double storey extension usually needs more detailed planning, design and structural work than a single storey extension. Side extensions of more than one storey will generally require householder planning permission, and two-storey projects must meet specific planning and design criteria.
Kitchen Extension
A kitchen extension is one of the most common home extension ideas because the kitchen has become the centre of many homes.
Older properties often have small kitchens separated from the dining or living room. A kitchen extension can create a brighter, more sociable space with room for cooking, eating, relaxing and entertaining.
Popular kitchen extension features include:
Open-plan layouts
Kitchen islands
Roof lanterns or skylights
Bi-fold or sliding doors
Utility rooms
Dining areas facing the garden
A kitchen extension is not only about gaining extra floor space. It is about improving the way the whole ground floor works.
Garage Conversion
A garage conversion can be a practical alternative to a full extension, especially when the garage is rarely used for parking.
A garage conversion can become a home office, gym, playroom, guest room, utility room or extra living space. Because the main structure is already there, it may be less disruptive than building a new extension, although insulation, flooring, electrics, heating, ventilation and fire safety all need proper consideration.
This option works particularly well for homeowners who want more internal space without building into the garden, like this garage conversion in Weybridge.
Conservatory
A conservatory can add a bright, garden-facing room to the home.
A conservatory usually has more glazing, while an orangery often feels more solid and room-like, with brickwork, a lantern roof and better integration with the existing property. Both can be used as dining rooms, sitting rooms, playrooms or relaxing spaces overlooking the garden.
For year-round comfort, insulation, heating, ventilation and the quality of the roof system are important. A well-designed conservatory or orangery should feel like a useful part of the home, not just a room that is too hot in summer and too cold in winter.
Loft Conversion or Loft Boarding
A loft conversion uses the roof space to create an additional room, often a bedroom, office or bathroom. For homeowners who do not want to lose garden space, building upwards can be a smart option.
Not every loft is suitable for a full conversion, so head height, roof structure, access and building regulations all need to be reviewed. In some homes, loft boarding can also create useful storage space, even when a full conversion is not the right route.
At Creations Building & Landscaping, we help homeowners make better use of their existing space, including loft-related improvements and conversion work across Surrey and the surrounding areas.
Do You Need Planning Permission for a Home Extension?
Some home extensions can be built under permitted development rights, as long as they meet specific limits and conditions. If the proposed extension goes beyond those limits, a householder planning application is likely to be needed.
Planning permission depends on the property, the size of the extension, its height, where it sits on the plot, which means a home extension in Walton on Thames may differ from a garage conversion in Oxted. How close it is to boundaries and whether the home is in a designated area. Larger single storey rear extensions may also be subject to a neighbour consultation scheme.
Building regulations are separate from planning permission. In general, home extensions must comply with building regulations, even when planning permission is not required. This covers areas such as foundations, drainage, electrics, walls, windows, doors, roofs, kitchens, bathrooms and fire safety.
How to Choose the Right Home Extension
The best home extension is not always the biggest one. It is the one that solves the right problem.
Before choosing a design, it helps to think about:
What space is missing from the home
Whether the priority is more light, more floor area or a better layout
How much garden space can be used comfortably
Whether extra bedrooms or bathrooms are needed
How the extension will look from outside
Whether the project may need planning permission
How the new space will work in everyday life
For example, a side return extension may be ideal for a narrow kitchen, while a double storey extension may suit a growing family that needs both downstairs living space and another bedroom. A garage conversion may be the better choice where the structure already exists, while a rear extension may be perfect for creating a kitchen-diner that opens onto the garden.
