With property values continuing to rise in Hanwell and surrounding West London areas, many homeowners are opting for house extensions as a practical and cost-effective alternative to moving. Whether you are expanding to accommodate a growing family, building a dedicated workspace, or increasing long-term property value, a well-executed extension can significantly enhance both functionality and aesthetics.

At Crest Projects, we provide high-quality, bespoke house extensions in Hanwell, offering a full design-and-build service tailored to each property’s architecture and the homeowner’s needs. Our experience across residential projects in West London ensures seamless project delivery that meets local planning guidelines, budget expectations, and lifestyle goals.

The Demand for House Extensions in Hanwell

Hanwell, located in the London Borough of Ealing, is known for its family-friendly streets, green spaces, and Victorian and Edwardian homes. As demand for living space continues to grow, extending an existing property has become one of the most desirable home improvement solutions for residents in the area.

Homeowners in Hanwell often face constraints with plot size and development restrictions. Therefore, working with an experienced, locally focused construction company such as Crest Projects ensures that planning regulations are adhered to and space is used optimally.

Types of House Extensions We Offer

Every home and family is unique. At Crest Projects, we provide a wide range of house extension solutions to suit all types of properties and purposes.

1. Rear Extensions

Rear extensions are ideal for homeowners looking to expand kitchen or dining areas into the garden. We design and build single or double-storey rear extensions that blend seamlessly with your home’s existing design while maximising interior space.

2. Side Return Extensions

Common in Victorian and Edwardian terraced homes across Hanwell, side return extensions fill in the unused alleyway beside the property. These projects often significantly improve kitchen layouts and introduce open-plan living without sacrificing garden space.

3. Wrap-Around Extensions

A combination of side and rear extensions, this option dramatically increases ground floor area and is perfect for creating large, light-filled kitchen/living spaces. Our team ensures the structural integrity and architectural harmony of the entire property is preserved.

4. Double-Storey Extensions

For homeowners needing more bedrooms, bathrooms, or office space, a double-storey extension offers increased capacity with long-term investment value. These projects require careful structural design, all of which is managed by our in-house engineers and architects.

5. Over-Structure Extensions

Extending over an existing garage or single-storey structure can be an effective way to gain additional living space. Crest Projects provides a detailed feasibility study before commencing to ensure the structure supports additional load and meets building regulations.
