EXTENSION PLANS

01.

SIDE RETURN
EXTENSION

A side return extension widens the unused space along the side of your property, often known as the outrigger. These extensions are commonly found on Victorian properties with L-shaped layouts, but they can be designed for homes of any age.

Side return extensions are a cost-effective way to increase living space, creating a brighter and more open layout with minimal impact on your garden.

04.

DOUBLE STOREY

EXTENSION

A double storey extension can be built at the side or rear of a property, or as a combination of both to create a wrap-around design.

Adding space to both floors allows for larger living areas downstairs and additional bedrooms upstairs, making this an ideal solution for growing families.

02.

REAR EXTENSION

A rear extension projects outward from the back of your property, increasing the size of your ground floor. These extensions are ideal for kitchens, dining rooms, and living areas, creating spacious and modern open-plan environments.

Rear extensions work particularly well for homes with sufficient garden space, and features such as large windows or bifold doors can create excellent indoor–outdoor living areas.

05.

A wrap-around extension combines a side return extension with a rear extension to create a large and versatile living space.

This type of extension adds significant floor area and is ideal for modern open-plan layouts, making it one of the most effective ways to transform your home.

WRAP AROUND

EXTENSION

03.

SIDE EXTENSION

A side extension is built along the side of a property, often using the narrow passageway that runs alongside many semi-detached or detached houses.

This type of extension can significantly increase the size of your home while preserving valuable garden space.
