As residential demand continues to rise across West London, homeowners are increasingly exploring intelligent ways to expand their living space without the complexities and costs associated with relocating. A house extension presents a strategic and practical solution, enhancing property functionality while simultaneously increasing its long-term market value.

At Crest Projects, we specialise in delivering high-end house extensions in West London, combining architectural excellence with construction proficiency. Our end-to-end service model ensures each project is tailored, compliant, and executed to the highest standards—on time and within budget.

The Benefits of Extending Your Home in West London

Whether located in Chiswick, Ealing, Fulham, Acton, or Hammersmith, properties in West London are often limited by external expansion opportunities. However, thoughtful and well-executed house extensions offer numerous benefits:

• Increased Living Space: Perfect for growing families, home offices, or entertainment areas.
• Enhanced Property Value: Professionally completed extensions can add up to 25% to the home’s value.
• Improved Comfort and Functionality: Allows for reconfiguration of space to better suit evolving lifestyle needs.
• Avoidance of Moving Costs: Extensions eliminate the need for expensive relocations in a competitive market.
• Personalised Design: The extension can be customised to reflect your design preferences and architectural vision.

Our House Extension Services

Crest Projects provides a comprehensive range of house extension solutions, each designed to meet specific property types, local council regulations, and individual client goals.

1. Rear Extensions

A popular choice among homeowners, rear extensions make use of garden space to expand key living areas such as kitchens, lounges, and dining rooms. We offer single and double-storey rear extensions, fully integrated with your existing layout.

2. Side Return Extensions

Especially suited for Victorian and Edwardian homes, side return extensions utilise narrow alleyways to the side of the property, turning underused space into functional square footage. They are ideal for creating open-plan living environments.

3. Wrap-Around Extensions

Combining both side and rear extensions, wrap-around solutions deliver substantial ground floor area. These are perfect for modern kitchen/living room combinations that benefit from increased light and flow.

4. Double-Storey Extensions

When both ground and upper-level expansion is needed, double-storey extensions offer a comprehensive solution. Our structural engineers ensure that these projects are built safely and in accordance with all building regulations.

5. Over-Structure Extensions

Ideal for homes with existing garages or single-storey wings, this extension type adds living space vertically, without compromising garden or outdoor space.
