Small House Extension Ideas

When it comes to small houses, making the most of every inch of space is crucial. Luckily, there are plenty of innovative and creative small house extension ideas that can help you maximise your living area without compromising on comfort or style.

Side Return Extension

Many periodic terraced and semi-detached houses have a narrow outdoor area that runs down the side of the property, called the side return. But what is the use of that wasted space? By extending the width of your property, you can create a larger kitchen, dining area, or multifunctional space that seamlessly blends with your existing layout.

Lean To Conservatory

A lean-to-conservatory is an excellent choice if you want to bring more natural light into your home. This extension option is constructed from a simple structure that leans against the existing wall, providing an elegant and sunlit space that can serve as a cosy lounge area or an indoor garden sanctuary!

Box Dormer Extension

For homes with limited land to expand outwards, a box dormer extension can be an ideal option. This involves creating a box-shaped structure that protrudes vertically from the existing roof, adding valuable headroom and floor space to your cramped loft, and turning it into a functional, spacious area. With a dormer loft extension, you can add a spacious extra room to your property without compromising on your outdoor living space.

Connect With The Outdoors

To make your small space appear larger, consider incorporating large windows, bi-fold doors, or a glass roof extension to establish a stronger connection between your indoor and outdoor spaces. This approach allows for an abundance of natural light, panoramic views, and a sense of openness, bringing the beauty of the outdoors inside.

Rear House Extension Ideas

If you want to enhance the living space at the back of your house, rear house extensions not only allow you to add valuable square footage to your property but also offer endless possibilities for designing open-plan living areas, incorporating stunning glass features that flood your home with natural light, or embracing the beauty of new materials. Discover our favourite rear house extension ideas to unlock the full potential of your living space and bring your vision of a modern, functional, and aesthetically pleasing home to life.

Modern Rear Extension

Open-Plan Kitchen and Dining Area

Create a spacious and inviting environment by extending your home at the rear to accommodate an open-plan kitchen and dining area. This design not only provides a seamless flow between the two spaces but also enhances the overall functionality of your home, leaving you with a lovely open space to entertain your friends and family throughout the year.

Orangery Extension

For those who desire a blend of traditional and contemporary styles, an orangery extension offers a luxury solution as it combines the structural integrity of an extension with the benefits and aesthetics of a conservatory. With its brick or stone base and large glazed panels, an orangery provides a versatile space that can serve as a sunroom, home office, or a tranquil retreat for when you need a moment to relax.

Timber Cladding Extension

Why not embrace a rustic and natural aesthetic by incorporating timber cladding in your rear house extension? This increasingly popular choice adds character and warmth to your home’s exterior while creating a unique and inviting atmosphere inside.

Indoor-Outdoor Transition

To seamlessly transition from your indoor living space to your outdoor oasis, a rear house extension that features a patio, deck, or veranda area is a classic option. This arrangement enables you to enjoy the best of both worlds, creating a harmonious connection between your home and the surrounding landscape, whilst also providing a comfortable outdoor living space.
