The increasing demand for adaptable, spacious, and functional homes has led many London homeowners to consider extending their current properties rather than relocating. A well-designed house extension not only adds valuable space but also significantly increases the overall property value.
At Crest Projects, we offer premium house extension services in London, delivering tailored solutions that meet individual lifestyle needs and architectural standards. From initial consultation and design to regulatory approval and construction, our experienced team ensures each project is completed with precision, professionalism, and long-term value in mind.
Why Invest in a House Extension in London?
London’s housing market is highly competitive, and for many families, relocating to a larger property is often impractical due to costs, school proximity, and location preferences. Extending an existing home offers a strategic alternative that enhances living conditions without the disruption of moving.
Key benefits of house extensions include:
- Increased living space for growing families or evolving needs
- Higher property value, offering an excellent return on investment
- Improved home functionality, such as open-plan kitchens or dedicated workspaces
- Design flexibility, allowing the space to reflect your personal style
- Avoidance of moving expenses, legal fees, and stamp duty
Our Range of House Extension Services
Crest Projects offers a complete spectrum of house extension services across London. Whether you live in a terraced townhouse in Islington, a detached property in Richmond, or a semi-detached home in Ealing, we provide bespoke design-and-build solutions suitable for all property types.
1. Rear Extensions
A rear extension is ideal for enlarging the ground floor, particularly kitchens and living areas. These extensions often lead into the garden and can be built as single or double-storey structures.
2. Side Return Extensions
Side return extensions are particularly popular in Victorian and Edwardian terraced homes. They utilise narrow passageways at the side of a property to widen interior space—perfect for open-plan living.
3. Wrap-Around Extensions
Combining rear and side return designs, wrap-around extensions provide substantial ground-floor expansion. They offer maximum layout flexibility and are ideal for modern family living.
4. Double-Storey Extensions
When space and planning permission allow, a two-storey extension can dramatically increase usable space. This option allows for the creation of additional bedrooms, bathrooms, or home offices upstairs.
5. Over-Structure Extensions
This type of extension is built above an existing structure, such as a garage or single-storey addition. It offers a cost-effective way to add living space without expanding the property’s footprint.
Our Design-and-Build Process
At Crest Projects, we provide a full-service solution that ensures a smooth and efficient delivery. Our integrated team manages every stage of the extension process.
● Initial Consultation and Feasibility
We begin with a site visit to assess the existing property and discuss your vision, requirements, and budget. During this phase, we advise on planning constraints, design options, and structural considerations.
● Planning and Architectural Design
Our architects create detailed drawings that reflect your preferences and comply with local authority regulations. We also handle all aspects of planning applications and permitted development approvals, ensuring compliance with UK building regulations.
● Structural Engineering and Compliance
Our structural engineers provide all required calculations and documentation to guarantee the safety and integrity of your extension. We adhere strictly to building regulations and work closely with building control inspectors throughout the process.
● Project Execution and Construction
Once approvals are secured, our construction team begins work under the guidance of an experienced project manager. We use only high-quality materials, maintain a clean and safe work environment, and communicate regularly with clients throughout the build.
● Interior Fit-Out and Final Finishing
We complete your extension to a turnkey standard, including electrical work, plumbing, plastering, flooring, and decoration. The finished product is fully integrated into your existing home in terms of both aesthetics and functionality.
