DO I NEED PLANNING PERMISSION FOR A LOFT CONVERSION?
Planning permission: two words that often fill a homeowner with dread ahead of a home improvement project. The issue of planning permission can be a complicated one, with different types of home improvements requiring different levels of planning consent. It is everyone’s worst nightmare to have their heart set on an extension or conversion, only to have planning permission denied at the last minute.
The good news is that loft conversions will rarely require planning permission, as the work carried out is classed as being within the general permitted development rights of your property. This means that in most cases, we will be able to design your new loft space and carry out the building work without the need for a potentially lengthy planning application process. Your loft conversion build could be completed in just six to eight weeks’ time.
WHAT ARE THE LIMITS AND CONDITIONS
FOR LOFT CONVERSIONS?
These are the limits and conditions that your loft conversion project will need to comply with if you are going to go ahead without planning permission:
- You will need to have 40 cubic metres of additional roof space if you have a terraced house
- This increases to 50 cubic metres if you have a detached or semi-detached house
- You cannot extend beyond the plane of the existing roof slope at its highest point
- The materials used must be aesthetically similar to those of your existing property
- You cannot install a veranda, balcony or raised platform (unless you have planning permission)
- Side-facing windows must be obscure glazed, and openings must be at least 1.7m above floor level
- Extensions should be set back at least 20cm from original eaves (hip to gable conversions are the exception)
- A loft conversion or enlargement can’t overhang the original house’s outer facing wall
Of course, it can be very hard to know if your design will work around these conditions without some expert advice. Talk to us and get your free, no-obligation quote to find out whether your future loft conversion will comply with these requirements.
WHEN MIGHT YOU NEED
If your loft conversion is going to fall outside of any of the conditions set out above, then you will need to have planning consent in place before the project begins. This is not common – we rarely need to help our clients through the planning process for a loft conversion – but it does happen, and you need to know that you are abiding by all the rules before embarking upon a project.
When you don’t have any experience of loft conversions it can be difficult to know if your project is going to comply with the limits and regulations set out in The Town and Country Planning (General Permitted Development) (England) Order 2015. These are some of the tell-tale signs that you might be heading towards a planning application:
- You live in a flat, maisonette or converted house
- You have previously modified or enlarged your property or roof space, using some or all of your permitted development
- Your house has been built using permitted development rights for a change of use
- You live in a listed building or in a conservation area
- You want to extend or alter your roof space
- You are having a mansard-style conversion, as this will usually alter the roof space; in our experience all mansard conversions we have completed have required planning permission
- You want to dramatically alter the appearance of your property
