Our House Extension Services

We design and build a wide range of residential extensions, tailored to your home and needs.

Extending your home is one of the best ways to create more space without the need to move. Whether you're looking to expand your kitchen, add additional living space, or redesign the layout of your home, the right extension can transform how your property works for you.


Our team delivers high-quality house extensions that are carefully planned, well-built, and designed to add space, value, and functionality to your property. From the initial planning stages through to the final completion, every project is managed with attention to detail, clear communication, and a focus on achieving the result you want for your home.


Rear Extensions
Rear house extensions are ideal for expanding kitchens, dining areas, and living spaces. By extending into the garden, you can create open-plan layouts that bring in more natural light and provide a seamless connection between your home and outdoor space.


Side Extensions
If your property has unused space to the side, a side extension can significantly increase the width of your home. This type of extension is often used to enlarge kitchens, add utility rooms, or improve the overall layout while maintaining the character of the property.


Double Storey Extensions
A double storey extension provides substantial additional space across two floors, making it a great option for growing families. Whether adding extra bedrooms, bathrooms, or larger living areas, careful planning and construction ensure the extension integrates naturally with the existing home.



Full Project Management
Managing an extension project can feel overwhelming, which is why every stage is carefully coordinated for you. From design coordination and planning support through to construction and final handover, the entire process is handled with a clear plan, ensuring your house extension runs smoothly from start to finish.

Our Extension Build Process

To ensure your house extension runs smoothly, every project follows a clear and structured process:

A successful house extension starts with careful planning and a well-managed build process. Each stage of your project is organised and delivered with clear communication, ensuring everything runs smoothly from start to finish.


Initial Consultation & Site Survey
The process begins with a site visit to assess your property and discuss your extension ideas. This allows us to understand your goals, review the available space, and offer practical advice based on your home, layout, and budget.


Design & Planning Support
If design or planning approval is required, guidance is provided throughout this stage to help move your project forward. This may include coordinating with designers or assisting you through the planning process to ensure your house extension complies with local regulations.


Clear Fixed Quotation
Before construction begins, you receive a detailed and transparent quotation outlining the full scope of the work. This ensures you understand exactly what is included, giving you confidence and clarity before the project starts.


Extension Construction
Once everything is agreed, construction begins. All extension works are carried out efficiently and safely, from foundations and structural work through to roofing and internal finishes, while keeping disruption to your home to a minimum.


Completion & Handover
When construction is complete, final inspections are carried out and finishing touches are applied. Your new home extension is then handed over fully completed and ready for you to enjoy.
