What is a non-habitable loft conversion?
A non-habitable loft conversion is a loft conversion that you can't live or sleep in. It can only be used for storage or other purposes like a home office, art studio, or home gym.
But non-habitable loft conversions still give you extra space without the complex process of a complete loft renovation.
For non-habitable loft conversions, like a storage conversion, make sure:
You keep your folding stairs - don't go for a fixed staircase
Your storage conversion does not look habitable - keep the fixtures and fittings minimal
The walls are clearly not suitable for habitation - don't plaster the walls, keep the drywall
You only use your partial conversion for storage or extra space - not a bedroom or separate living space

Is it illegal to convert a loft without building regulations?
That depends on whether you plan to convert your loft fully or whether you're planning to create a non-habitable loft conversion.
If you plan to convert your loft fully, you'll need to comply with building regulations. These are in place to ensure construction work is safe and high-quality. Without them, you might also find it challenging to sell your property in the future
On the other hand, you can normally build a non-habitable loft conversion without needing a building code inspection.
Remember to check whether you need planning permission for your loft conversion as well. While many loft conversions fall under permitted development rights there are exceptions, so it's always safest to check with your local planning authority.
