Extension Guides

Explore the different ways to extend your home

A well-designed extension can transform the way a home works.

​

It may create a brighter kitchen and dining space, provide room for a growing family, improve access to the garden, add a home office or create more flexible living space for the years ahead.

​

However, not every extension suits every property.

​

The right solution will depend on the type of house, the available space, the planning position, the budget and the way you intend to use the new room.

​

APN Extensions has created a series of practical homeowner guides covering the most common types of house extension.

​

Use the guides below to explore the options and understand which approach may be best suited to your home.

​

​

Rear Extensions

 

Rear extensions are one of the most popular ways to improve a home.

​

They can create a larger kitchen, dining area or family room while providing better access to the garden. They work well on many different types of property, from terraced houses and semi-detached homes to bungalows and detached houses.

A modest rear extension can often make a major difference when combined with a thoughtful internal layout.

​

Side-Return Extensions

 

Side-return extensions are particularly popular on Victorian and Edwardian terraced properties.

​

They make use of the narrow strip of land beside the existing rear addition, often allowing a cramped kitchen to become a much brighter and more practical space.

​

A side-return extension may not add a huge amount of floor area, but the impact on the layout can be substantial.

​

Wraparound Extensions

 

A wraparound extension combines a rear extension with a side-return addition.

​

This can create a much larger kitchen, dining and family room with improved natural light and a better relationship with the garden.

​

Wraparound extensions are especially effective on period terraced and semi-detached homes where the existing layout feels narrow or fragmented.

​

Double-Storey Extensions

 

A double-storey extension can provide valuable additional space on both the ground and first floors.

​

It may allow for a larger kitchen and living area downstairs while adding a bedroom, bathroom or home office upstairs.

​

These extensions need careful planning and good proportions so that the finished design complements the original house rather than overwhelming it.

​

Full-Width Extensions

 

A full-width extension spans most or all of the rear elevation of the property.

​

This approach can work particularly well where the homeowner wants to create a generous open-plan kitchen, dining and family space with wide garden doors and plenty of natural light.

​

The layout needs to be carefully planned so that the new room feels balanced and practical rather than simply large.

Bungalow Extensions

 

Bungalows often provide excellent opportunities for extension.

​

A well-planned addition can create a larger kitchen and dining space, an additional bedroom, a garden-facing living room or a more practical layout for long-term living.

​

Because bungalows vary considerably in size and style, the design should respond carefully to the roof shape, available garden space and existing accommodation.

​

Kitchen and Diner Extensions

 

Many homeowners extend primarily to create a better kitchen and dining space.

​

A successful kitchen-diner extension should feel bright, sociable and practical. It should provide enough room for cooking, storage, family meals and entertaining without losing a comfortable relationship with the rest of the home.

​

The best designs also consider utility space, lighting, garden access and the position of furniture from the outset.

​

Side Extensions

 

Side extensions can be particularly useful for semi-detached, end-of-terrace, detached and bungalow properties with space beside the house.

​

They may provide a home office, utility room, ground-floor bedroom, en-suite bathroom, family room or semi-independent space for an older relative or teenager.

​

The design needs to be carefully proportioned so that the extension sits comfortably with the original property and does not appear squeezed into the site.

​

Orangery Extensions

 

An orangery can create one of the most elegant rooms in the home.

​

These extensions often include a central roof lantern, refined glazing, French doors and a strong connection with the patio and garden.

​

They work particularly well as dining rooms or entertaining spaces and are best suited to homes with enough scale and garden space to carry the design properly.

​

Conservatory Extensions

 

Modern conservatory extensions have improved significantly.

​

Better glazing, insulated frames, solar-control glass and a wider range of roof options mean that a well-designed conservatory can provide a bright and practical garden-facing room.

​

They can offer an attractive alternative where the homeowner wants additional dining, sitting or entertaining space without committing to a full brick-built extension.

​

Extensions and Loft Conversions

 

Some homeowners choose to extend at ground-floor level while also converting the loft.

​

This can be an effective way to improve the entire property, creating a larger kitchen and family space downstairs while adding bedrooms, a bathroom or a home office above.

​

The two projects should be considered together so that the overall budget, planning strategy, staircase position and internal layout are coordinated properly.

​

Choosing the right extension

 

The largest extension is not always the best extension.

​

A good design should make the property work better, improve the quality of the space and add long-term value without overdeveloping the site.

​

Before deciding which route to take, consider:

​

  • The type and character of the property;

  • The amount of garden space available;

  • The existing internal layout;

  • The way you want to use the new room;

  • The likely planning constraints;

  • The overall project budget;

  • The professional and construction work required.

​

A modest extension with a well-planned layout can often provide better value than a much larger scheme that has not been carefully considered.
