Thinking about adding more space and value to your home?

You are not alone. 

Many homeowners across the country are now investing in extensions to improve comfort and increase the property value. However, not all additions bring the same return. That’s where careful planning can make a significant difference.

Whether you’re planning a future sale or simply want to optimise your space, understanding the ROI of each type of extension helps you make the right decision. If you’re exploring house extensions in Worthing, explore the most valuable options right now.

Kitchen Extensions: The Heart of the Home

Open-plan kitchen extensions remain one of the top choices for homeowners. They completely transform living spaces, creating the perfect area for entertaining, dining, or family time. A spacious kitchen-diner often boosts the appeal of a house and add up to 15% to the property’s value. It also improves daily living by increasing natural light and flow. 

Loft Conversions: Maximise Unused Space

Turning your loft into a bedroom or home office is one of the smartest ways to add space. It doesn’t eat into your garden and usually costs less than other extensions. In most cases, loft conversions can add up to 20% to your home’s value. They also work very well for growing families or remote workers. 

Rear and Side Extensions: More Room & Better Flow

A single-storey rear or wraparound extension opens up your living room, dining area or even both. These additions improve home layout and enhance natural light.

This type of extension offers flexibility in design and function. You could add a playroom, a sunroom, or a bigger lounge. Depending on location and design, you could see a return of 10–15% in added property value.

Garage Conversions: Low Cost but Big Impact

Converting an existing garage provides more living space without the high construction costs of a full extension. Many homeowners use it for a home office, gym, or ground-floor bedroom.

Garage conversions usually cost less and can offer up to 10% ROI. Planning permission is usually not required, especially when converting an integral garage. 

What Impacts the ROI on House Extensions?

Several factors influence how much value an extension adds. These include your postcode, the quality of the build, and current market demand in your area. Always research similar properties in the area before starting. Ensure your extension aligns with your home’s style and local buyer expectations. 

House extensions come in many forms, but not all deliver the same return on investment. Focus on what suits your lifestyle and the local market. If you’re planning house extensions in Worthing, speak to trusted local experts like Creative IP. Reach out to us now.
