FAQs

an every house have a loft conversion?

If you’re having issues with the amount of space in your home and need an extra space without affecting your garden, loft conversion comes to mind. Not only is it a great solution to creating more living space within a home, but it’s also one of the most budget-friendly solutions you can count on to expand your space by thinking upwards rather than sideways. So if you’re thinking about converting your loft, one thing that almost immediately comes to mind is whether or not your house is suitable for loft conversion.

To answer the question of whether every house can have a loft conversion is a very simple one. Generally, not every house is suitable for loft conversion. This is due to the fact that each and every loft space - from the stairways below and floors to the rafters and the roof up above, is unique. Therefore, the best way to really figure out whether or not a house’s loft offers the potential for conversion is to get in touch with a loft specialist.

So what can make a house not suitable for a loft conversion? Let’s take a closer look!

✓ A house will not be suitable for a loft conversion if the height of the ceiling happens to be too low and it’ll not be possible to have it raised.

✓ If you do not own own the freehold to the loft space, you won’t be able to convert the loft. Surprisingly, this happens to be a common issue in London.

✓ You will not be able to convert your loft if you reside in a conservation area or in a listed building. But you can identify a design solution that’ll still comply with the conservation rules and keep planners happy.

what is a hip to gable loft conversion?

This is a type of loft conversion that extends your roof on the sloping side. It is a great option to go for especially where a hipped roof effectively makes the usable floor area a lot smaller which can be a tricky affair when it comes to putting in a new staircase. Here, the roof is extended from the current ridge in such a way that it effectively fills the gap between them. As a result, this turns the hip (in a hipped roof) into a gable to create space in your roof for a loft conversion - hence the name “hip to gable.

The new gable can be done in whatever way that suits both your taste as well as your property. You can make the new gable construction in woods and then tiled to match your existing roof while you can also go for other options such as brick block pebbledash or rendering. You are also free to fit in a new window into the loft conversion end so as to allow for natural light into the loft space.

A hip to gable loft conversion is mostly found on both semi detached and end terrace buildings, particularly those constructed in the 1930s. Overall, this type of loft conversion is particularly ideal for homes that features a hipped roof and with a sloping roof at the side of the property. Some detached properties can also possess a hipped roof on the side - and as such, a double hip to gable loft conversion can also be deal as it’ll create more loft space for usage. If your home fits into the bill, then you should be aware that once the project is completed, you’ll have plenty of usable space available to both you and your loved ones.

How long will a loft conversion take?

It depends on the style and size of the conversion, but in general, a loft conversion will take between 1-2 months. A loft conversion is a substantial building project, and plans will need to be drawn up. This may add to the time it takes to complete your loft conversion.

Will I need planning permission to convert my loft?

Planning permission is not normally needed for a loft conversion as they are covered by permitted development rights. A conversion company will tell you if you do and help you with this. For more information, see our article about planning permission.
