A loft conversion can add up to 30% more living space to your home and up to a fifth onto the value of your home. It’s a fantastic way to expand without giving up areas of your garden or your garage – in the majority of homes, loft space is only used for storage (if at all) while gardens are enjoyed throughout summer.
Do I Need Planning Permission for a Loft Conversion?
Like house extensions, some loft conversions can be built as permitted developments. This depends on the type of loft conversion, where you live, and whether your home has already had permitted developments built. If you have already built a house extension as a permitted development, for example, you will not be able to add more permitted developments to your home (even if that extension was built by a previous owner). Velux loft conversions can typically be built without planning permission, whereas Mansard loft conversions make more extensive changes to the exterior of your home so usually require planning consent.
Loft Conversion Types
There are a few different types of loft conversion:
- Velux loft conversions do not make extensive roof changes – they just add windows to provide light and ventilation to the loft space and most of the changes are internal. These are typically the cheapest and fastest to build, and can usually be completed as permitted developments.
- Dormer loft conversions are much like Velux conversions, but instead of windows that are flush with the roof, they add ‘dormers’ to the roof. These are small boxes that contain the windows – they allow the windows to look out at the same angle as the rest of the windows in the house, rather than facing upwards towards the sky. The dormers provide a little more head height within the loft space.
- Hip to gable loft conversions can only be built on homes with hipped roofs – this is when the end of the roof is tilted inwards, rather than following the line of the wall straight up. Opening up the roof like this provides more head room – these loft conversions typically require planning permission and require either Velux windows or dormers for light.
- Mansard loft conversions completely change the space of the roof to open up at least one side to create 4 sides, rather than 3. The angles mean that the rooms within these loft conversions are far more spacious and do not feel like a loft conversion, however extensive changes to the exterior mean that these loft conversions require planning consent.
