Expanding your home is one of the most effective ways to create more living space without the stress and expense of moving. At Redline Building Services, we specialise in high-quality house extensions in London, helping homeowners transform their properties to better suit their lifestyle and growing needs.
Whether you want a larger kitchen, an open-plan living space, or an extra room for work or relaxation, a professionally built extension can significantly increase both the comfort and value of your home. With property prices in London continuing to rise, extending your existing home is often a smarter and more cost-effective investment than relocating.
Our experienced team of builders in London understands the complexities of including local planning rules, property styles, and structural considerations. From the first consultation through to final completion, we manage the entire process with precision and care. We work closely with architects, engineers, and local authorities to ensure every extension is safe, compliant, and built to the highest standard.
If you are looking for reliable house extension builders in London, our team is here to help you unlock the full potential of your property.
Every home is different, which is why we offer a range of extension options tailored to London properties. From compact terraced homes to larger family houses, we design and build extensions that maximise space and improve functionality.
Rear extensions are one of the most common types of house extensions in London. They extend the property into the garden, creating additional living space without altering the front of the home. Many homeowners choose rear extensions to create larger kitchens, dining areas, or open-plan family rooms. With modern glazing, skylights, and sliding doors, rear extensions can also bring more natural light into your home and create a seamless connection with the garden.
Side return extensions are especially popular with London terraced and semi-detached homes. These projects utilise the narrow passageway often found along the side of the property. By building into this unused space, homeowners can significantly widen their ground floor and create spacious kitchens or living areas. A well-designed side return extension can completely transform the layout of a traditional London home.
A wrap around extension combines both a rear extension and a side return extension to create a large L-shaped addition. This type of extension provides the greatest opportunity for redesigning the internal layout of your property. Wrap around extensions are ideal for creating large open-plan kitchens, dining rooms, and living spaces that suit modern family life.
Kitchen extensions are one of the most sought-after home improvement projects in London. Many older homes have small, enclosed kitchens that no longer meet the needs of modern living. By extending the property, we can create spacious open-plan kitchens with dining and living areas. Features such as roof lanterns, bifold doors, and contemporary layouts can transform the kitchen into the central hub of the home.
A successful house extension requires careful planning, expert construction, and clear communication. Our structured process ensures every project runs smoothly from start to finish.
01
We begin with an initial consultation to understand your goals, ideas, and budget. Our team will visit your property to carry out a detailed site survey and discuss the best options for your extension.
02
Once the project scope is agreed, we work with professional architects to develop detailed drawings and plans. At this stage we also review planning requirements and ensure the design complies with local building regulations.
03
The structural stage includes groundwork, foundations, drainage, and structural supports such as steel beams. Our team works closely with structural engineers to ensure the extension is safe, stable, and built to specification.
04
During construction, our builders complete the main structure, roofing, windows, internal walls, and services such as plumbing and electrics. We then move on to interior finishing, including plastering, flooring, and fittings.
05
Before project completion, we carry out a full inspection to ensure every detail meets our quality standards and building regulations. We also coordinate with architects, structural engineers, and local planning authorities where required.
Many homeowners are unsure whether planning permission is required for a house extension. The answer depends on the size, location, and design of the proposed extension.
Some smaller extensions fall under permitted development rights, meaning planning approval may not be necessary. However, there are still strict limits regarding size, height, and proximity to neighbouring properties.
For larger or more complex projects, formal planning permission from the local council may be required. Our team can guide you through this process and ensure all documentation is prepared correctly.
In addition to planning approval, house extensions must also comply with building regulations. These regulations ensure the structure is safe, energy efficient, and properly constructed.
If your extension affects a shared wall with a neighbouring property, you may also need a party wall agreement. We can assist homeowners in understanding these requirements and managing the process smoothly.
