Which Home Extensions Add the Most Value to Your Property?

When it comes to boosting the value of your home, choosing the right home extension ideas is key. Not all extensions are created equal; some can increase your property’s market appeal, while others might not add as much as you’d hope. If you’re based in London or the South West area, you’re probably wondering where to start.  

In this blog, we’ll explore which types of home extensions add the most value and what to consider before starting your project. Here’s everything you need to know. 

What Type of Extension Adds the Most Value? 

Extensions are a fantastic investment, but if you want maximum returns, it pays to plan wisely. 

Single storey extensions are incredibly popular, especially for adding spacious, open-plan kitchen diners — one of the most sought-after features for UK buyers. A beautifully designed single storey extension can add around 5–8% to your home’s value. 

Double storey extensions or two storey extensions offer even more bang for your money. By doubling up the extra space (living area downstairs and extra bedrooms or a bathroom upstairs), you could see a 12–20% increase in value. If you’re wondering about the cost of a double storey extension project, yes, they are higher than single storey builds, but the potential financial return often makes them a very savvy choice. 

Loft conversions are another winner, especially in South West London, where space is at a premium. Turning unused roof space into a bedroom with an en-suite can add significant value without using up precious garden area. 

What is the Most Expensive Part of a House Extension? 

It’s no surprise that the biggest costs often lie in the unseen essentials, not the glossy finishes. The most expensive part of a house extension typically includes: 

1. Foundations: Groundwork is complex and costly, especially if the soil conditions aren’t ideal.
2. Structural changes: Removing walls and supporting new sections with steel beams racks up the price.
3. Plumbing and electrics: Particularly for kitchen or bathroom extensions, fitting new systems can be a significant portion of the budget.
4. Roofing: Flat or pitched roofs have their own challenges and costs. 

Working with an experienced team like Doran Bros Construction ensures you avoid hidden surprises. Their in-depth planning and transparent quotes help you stay in control of your extension costs without cutting corners. 

Impactful Small Home Extension Ideas 

If a full-scale extension isn’t quite right for you, there are still plenty of small home extension ideas that can make a huge impact. Think about a side return extension to widen a narrow kitchen or adding a cosy garden room to create a home office. Even a modest porch extension can change the feel of a property and boost kerb appeal. 

Small doesn’t have to mean insignificant; with clever design and quality workmanship, smaller projects can still add impressive value and improve your daily life.
