Is Your Loft Convertible?

If you’re considering extending your living space in the form of a loft conversion, you should check whether your loft is actually convertible before you get your hopes up. Some lofts may require significant structural changes before they can be habitable and you may not consider this to be a valuable investment. So, how do you know if your loft is convertible?


As with any investment, the size of your budget is the main determinant in whether or not you can convert your loft. The overall cost of a loft conversion depends on several factors but normally ranges between £10,000 and £40,000. Speak to a professional if you want to gauge an idea of how much you will end up spending.

Head Height

Once you’ve determined whether or not your budget will cover the cost of a loft conversion, you should start by measuring the head height. Anything less than 2.4m at the tallest point will not be a worthwhile conversion, even if you think it looks like there’s enough room. Bear in mind that you will have to allow for flooring and roof insulation which will take up space and you do need to be able to stand up comfortably.


Even with satisfactory head height, you also need space for a permanent staircase. This is a legal requirement. There is no benefit to adding “extra” space if you have to sacrifice space on the floor below to fit a new staircase.

Planning Permission

Any major alterations to the structure of your roof will likely require formal approval to ensure it complies with the local guidelines. However, many types of conversions do not need planning permission. It’s best to check this to stay on the safe side.

Before you start planning your loft conversion, you should be able to get a rough idea of what is or isn’t possible without the need for professional support. You may find that nothing is impossible, but some things may take a little extra work. In the end, it all depends on what you and your family require, in order to make the most of the additional room in your house.
