Can I convert my loft? The short answer is yes, but there are a lot of factors to take into account before you convert your loft. There are a number of different requirements relating to head height and floor area, as well as certain building regulations that you have to comply with.
A loft conversion is one of the most popular ways to add space and value to your home. And while it can be a relatively straightforward process, there are still some key questions you’ll need to answer before you start:
As loft conversions go, a basic rooflight conversion is usually the easiest, cheapest and fastest way to add space. But first you’ll need to check that your existing roof will support the extra weight of a converted loft, as well as the new staircase needed to access it.
If your home is in an area prone to subsidence or flooding, or has listed building status, you may need planning permission for the conversion. Otherwise all types of conversion should be covered by permitted development rights – but if in doubt, check with your local planning authority.
What Loft Conversion Should I Choose?
There are four main types of loft conversion: rooflight, dormer, hip-to-gable and mansard. Each has its own advantages and drawbacks – see our Loft Conversion Guide for details – so finding one that’s right for your property and budget will depend on what’s practical and what works best aesthetically.
If you are considering converting your loft, the first thing to do is to check with your local planning authority to see whether you require planning permission. If it is a simple conversion, it may be possible to carry out the work under what is known as permitted development rights.
As a rule of thumb, if the changes are not visible from outside the property and do not exceed 50 cubic metres for terraced houses or 40 cubic metres for detached and semi-detached houses, then the work can be carried out without planning permission. If you have any doubts or concerns, consult with your local authority before starting work.
If you have a listed building, or live in a conservation area, then you will probably need planning permission. Even if you don’t need planning permission, it is wise to inform your local authority of your intentions – they may have some ideas or advice that could help.
Even if you don’t need planning permission for your loft conversion, building regulations will still apply. These cover everything from insulation to fire safety, water supply and drainage, heating and ventilation.
