The value of adding an extra bedroom

If you’ve ever thought about moving or renovating, you’ve probably wondered whether adding another bedroom could boost your property’s value. After all, extra space is always appealing – whether it’s for growing families, guests, or even as a home office. But the big question is: how much does an extra bedroom add to home value? The short answer: it depends. Let’s break it down. 


Why an extra bedroom matters

For many buyers, bedrooms are one of the first things they look at when comparing properties. An extra bedroom can:

  • Make your home more attractive to families who need the space

  • Add flexibility (think: guest room, office, or even rental income potential)

  • Help your home stand out in a competitive market

In short, more bedrooms usually mean more interest from buyers – and that can push up your home’s value.

How much value could it add?

While there’s no fixed figure (since it depends on your location, property type, and market conditions), studies suggest that adding a double bedroom can increase your home’s value by up to 10–15%. For example, if your home is worth £250,000, that could mean an uplift of around £25,000–£37,500. That said, the cost of the work matters. A full loft conversion or extension could easily run into the tens of thousands, so it’s worth weighing up whether the potential increase in value outweighs the spend. Other ways to increase your home’s appeal Adding a bedroom isn’t the only way to boost your property’s value. Small, cost-effective upgrades can also make a difference, such as:

  • Refreshing kitchens and bathrooms

  • Improving energy efficiency (like adding insulation or upgrading windows)

  • Tidying up your garden and kerb appeal

These changes may not add as much raw value as another bedroom, but they can make your home easier to sell and help it stand out.

Over 55? Equity release could be an option

If you’re over 55, another way to finance big home improvements – like adding a bedroom – is through equity release. This lets you unlock some of the money tied up in your home without having to sell it. There are different types of equity release, but the most common is a lifetime mortgage, where you borrow against your home’s value and repay when the property is eventually sold. It won’t be right for everyone – equity release can reduce the inheritance you leave and may affect your entitlement to certain benefits. But for some, it’s a flexible way to fund renovations and enjoy the value of your home today.

The bottom line

So, how much does an extra bedroom add to home value? On average, it could boost your property’s price by around 10–15%, but the final figure depends on where you live, the quality of the work, and the demand in your local market. If you’re planning ahead, make sure to balance the costs with the potential gain – and think about whether the extra space will improve your day-to-day life too. Sometimes, the real value isn’t just in the price tag, but in how much more comfortable your home feels.
