How Much Does a Hip to Gable Loft Conversion Cost?

If you’re thinking about extending your home upwards, a hip to gable loft conversion might be the perfect solution. It’s one of the best ways to utilise unused space in your attic, giving you a spacious and functional new space—without having to move house.

But let’s get to the real question—how much does a hip to gable loft conversion cost? The truth is, there’s no one-size-fits-all price. The cost depends on several factors, and in this blog, we’ll break them down so you can understand what to expect.

What Affects the Cost of a Hip to Gable Loft Conversion?

Every home is different, and so is every loft conversion. Here’s what plays a big role in the final hip to gable loft conversion cost:

Your Property Type

Detached, semi-detached, and terraced homes all have different requirements. Generally, semi-detached houses are the most common for hip-to-gable conversions, but terraced homes can benefit too.

Structural Changes

Some lofts are ready to go, while others need extra support. You might need to reinforce the floor, adjust the roof, or tweak the walls to make sure everything’s safe and solid.

Extras & Features

Fancy an en-suite bathroom? How about built-in storage or custom windows? The more you customise, the more the price will vary.

Your Location

If you’re in South London or South West London, demand for loft conversions is high, and this can impact costs. However, working with experts like Doran Bros Construction ensures you get the best pricing without cutting corners.

Do You Need Planning Permission for a Hip to Gable Loft Conversion?

Good news—most hip to gable loft conversions don’t require planning permission! Thanks to permitted development rights, you can usually go ahead without the stress of getting approvals.

However, there are exceptions. If you live in a conservation area, or a listed building, or want to add certain exterior features, you might need permission. The best way to be sure? Work with a trusted company like Doran Bros Construction, who can guide you through all the legal requirements.

Hip-to-Gable Dormer Loft Conversion: Is It Worth It?

A standard hip to gable loft conversion extends the sloping side of your roof, creating a full-height vertical wall. But if you want to maximise every inch of your attic, consider adding a dormer.

1. More headroom: A dormer extends the roof even further, making your new room feel spacious and airy.

2. Better lighting: Bigger windows mean more natural light, which makes the space feel inviting.

3. Higher property value: A well-designed loft conversion can significantly increase your home’s worth.

Not sure whether a dormer is right for you? Doran Bros Construction offers expert advice on the best options for your home.
