As families grow and lifestyles change, the need for more space becomes evident. Home extensions in London allow you to optimize your current living environment, providing additional rooms or expanding existing ones to better meet your needs. Whether you require a larger kitchen, an extra bedroom, or a dedicated office space, extending your home offers a practical solution to accommodate your evolving requirements.
Investing in a home extension is a strategic way to boost your property’s market value. Property extensions are highly desirable in London’s competitive real estate market, where additional square footage can make a significant difference. By enhancing your home’s layout and functionality, an extension not only improves your living experience but also makes your property more attractive to potential buyers, increasing its resale value.
Moving to a new home can be a costly and stressful process. Home extensions offer a more economical and less disruptive alternative, allowing you to stay in your beloved neighborhood while gaining the additional space you need. Instead of navigating the complexities of buying and selling property, you can enhance your current home to better suit your needs and preferences.
Single-storey extensions are a popular choice for homeowners looking to expand their living space without altering the overall structure of their home. This type of extension typically involves extending outwards from the existing structure, creating additional space on the ground floor. Single-storey extensions are ideal for enlarging kitchens, living rooms, or creating a new dining area, offering a seamless blend with the existing design of your home.
For those seeking more substantial changes, double-storey extensions provide an excellent solution. This type of extension involves adding space on both the ground and first floors, significantly increasing the overall footprint of your home. Double-storey extensions are ideal for adding multiple rooms, such as additional bedrooms or bathrooms, and can dramatically enhance both the functionality and value of your property.
Loft conversions offer a creative way to utilize unused attic space, transforming it into a functional and stylish living area. This type of extension is ideal for creating additional bedrooms, home offices, or even a private retreat. Loft conversions are particularly valuable in urban areas like London, where horizontal space is limited, and vertical expansion offers a practical solution to space constraints.
Basement conversions are another effective way to expand your living space, especially in properties with existing basements that are underutilized. Converting a basement can create additional rooms such as a home gym, cinema room, or extra storage space. This type of extension not only maximizes your property’s potential but also improves overall functionality.
Conservatories and garden rooms provide a unique extension option, blending indoor and outdoor living. These structures are typically constructed using glass or lightweight materials, creating bright, airy spaces that connect seamlessly with your garden or outdoor area. Conservatories and garden rooms are perfect for relaxing, dining, or enjoying the view of your garden throughout the year.
The process of home extensions in London begins with an initial consultation, where you discuss your needs, preferences, and budget with a professional designer or architect. During this phase, designers create detailed plans and 3D renderings to help you visualize the proposed extension. This stage is crucial for ensuring that the design aligns with your vision and complies with local planning regulations.
Once the design is finalized, the next step involves obtaining the necessary planning permissions and permits. Planning and permits are essential for ensuring that your extension complies with local building codes and regulations. A professional project manager or architect handles the paperwork and liaises with local authorities to secure the required approvals, ensuring a smooth and compliant construction process.
With permits in place, construction begins. Home extension services include comprehensive project management to oversee the construction process. This involves coordinating contractors, monitoring progress, and ensuring that the work is completed to a high standard. Effective project management ensures that the extension is built on time, within budget, and to your specifications.
After the structural work is complete, attention turns to interior design and finishing touches. Interior design services focus on selecting materials, fixtures, and furnishings that complement the new space and enhance its functionality. This includes choosing flooring, lighting, and paint colours, as well as installing cabinetry and other fixtures to create a cohesive and stylish finish.
The final stage of the home extension process involves a thorough inspection to ensure that all work meets quality standards and complies with regulations. A final walkthrough allows you to review the completed extension, address any issues, and ensure that the space meets your expectations. Once approved, the extension is officially handed over, and you can begin enjoying your newly expanded living area.
When selecting a provider for your home extension project, it’s essential to choose a company with extensive experience and expertise. Look for professionals with a proven track record of delivering high-quality extensions that meet client expectations. Experienced providers offer valuable insights, innovative solutions, and efficient project management, ensuring a successful outcome.
Home extensions should reflect your unique needs and preferences. Choose a service provider that offers customization and design flexibility, allowing you to tailor the extension to your specific requirements. Professional designers work closely with you to develop a bespoke design that enhances your home’s functionality and aesthetic appeal.
The quality of work and materials used in your extension project is crucial for achieving a durable and aesthetically pleasing result. Ensure that your chosen provider uses high-quality materials and employs skilled craftsmen to deliver a finished product that meets the highest standards.
Research customer reviews and testimonials to gauge the reputation of your chosen home extension service provider. Positive feedback from previous clients provides assurance of the company’s reliability, professionalism, and commitment to customer satisfaction.

Moving costs, stamp duty, and uncertainty in the housing market can make relocating impractical. A well-designed extension adds lasting value and lets you shape your living space exactly how you want it.
Navigating planning permission in London can be complex, but we're here to guide you through every step. Many smaller extensions fall under permitted development rights, meaning they don't require formal planning approval. However, if your property is in a conservation area, is listed, or if you're planning a larger or multi-storey extension, full planning permission will likely be required.
We handle all applications, liaise with local authorities, and ensure your project complies with both planning laws and building regulations.

We assess your existing property layout and listen to what you want from your new space—whether it’s a larger kitchen, additional bedroom, or open-plan living area.

It depends on the size and type of extension. Many single-storey rear extensions fall under permitted development rights, but larger or double-storey builds usually require planning permission. At London Core Construction, we handle all planning applications and liaise with your local council to ensure full compliance.
The cost of a house extension in London typically ranges from £1,800 to £3,500 per square metre, depending on the complexity, materials, and finishes. We provide transparent, itemised quotes after the initial consultation so you know exactly what to expect—no hidden costs.

In most cases, no. We plan the construction process to minimize disruption, and many clients remain in their homes throughout the build. However, this depends on the scale and location of the extension. We’ll advise you on the best approach during the planning phase.
