Extension Without Planning Permission
What Size Extension can I Build Without Planning Permission
Building an extension to your house is a big project! There are many things to consider before you start construction. You need to take into account the house's envelope, the house type, and whether or not it will be built from scratch or if there is an existing house on site.
What size of extension can I build without planning permission?
The size of extension you can build without needing to seek planning permission will depend on a number of factors including your house type, neighbouring properties and whether you're using the extension as part of an existing house or building from scratch. Your house extension could be up to three storeys high without planning permission, but if you're building house extensions which are more than one floor high then it's important that the extension is clearly in proportion to your house and doesn't look too big. If you plan on extending upwards rather than outwards, make sure there isn't a risk of flooding or other serious structural problems before beginning any work!
A good way to find out how much house space you have available for an extension in your particular location is by using a House Extension Calculator tool - just enter the dimensions of your house into the relevant fields, along with information about neighbouring properties and access points. This will give you an idea of whether adding another room would be possible for example. To get even closer to knowing exactly how much house space you have available for an extension, it's a good idea to speak with your local planning department or council.
If you do decide to go ahead and build the house extension of your dreams, make sure that all necessary permits are in place before starting work - this is especially important if there is any chance whatsoever that you will need permission from the government (such as for larger extensions). It can be time consuming and frustrating to apply for permissions after construction has begun!
It doesn't matter whether you're building an outbuilding or extending upwards; it takes a lot of skill and experience on the part of architects working for house builders in Derby. As well as being aware of current trends in home extensions, it is necessary to know about house design and planning law.
This is a good time to remind you that the house extension process can be stressful, especially when it comes to complying with planning regulations. It's common for homeowners who have put in an application for house building permission to worry that their proposal will get turned down. You don't want to lose your head over this.
A comprehensive list of house extension that can be done without planning permission is as follows:
Building an extension to house: YES - as long as it's not more than 24 square metres and no higher than the existing house. The roof pitch of your house can't be lowered either, nor should you change its type. This is a good idea because bay windows are very popular for this kind of work.
Loft conversion: Yes - but only if it doesn't go over 50% of the total internal floor space or make changes to any exterior parts like chimneys etc... If in doubt, don't do it! Don't forget that even though you may have planning permission for certain works on your home, people who live next door might still complain about noise pollution caused by building work. Remember also that there must not be any adverse effects on traffic or road safety .
You can extend outwards and you mustn't extend more than three metres beyond the house's rear wall. If your house is a Victorian one, there are no rules against extending upwards but it's worth contacting us before doing so because these properties have sloping roofs which might make this kind of extension difficult to do.
