FAQs

when do you need planning permission for a house extension?

If you’re planning on adding a house extension to your property, you’d probably be worried about whether or not your proposed extension would require a planing permission. Well, it may be relieving to know that not every house extension project would require a formal consent, and in fact, several extensions are covered by the permitted development rights. Not only can this save you a considerable amount of time especially at the project’s planning phase, but it’ll also save you money on the application fee. In the UK, single storey extensions to the house’s rear can be 3 metres deep for both semi detached houses and terraces or 8 metres deep for detached homes.

So how do you know when you’d require a planning permission for your home extension? Well, if your extension plan fits these criteria explained below, then your project is most likely going to be allowable as a permitted development.

• Extensions, which includes previous additions, must not go beyond half of the original house’s total surrounding land area.

• The main elevation, or side elevation where it fronts the highway, must not be extended forward.

• For single storeys, the rear additions must not extend more than the original house’s rear by more than 3 metres in both semi attached homes and terraces (4 metres for detached houses).

• Extensions to the side must be a single storey with a height not exceeding 4 metres and not going beyond 50% of the original house’s width.

• Extensions hat within 2 metres of a boundary should have a eaves height not more than 3 metres.

• Multi storey addition must not extend beyond the original house’s rear wall by a maximum of 3 metres or 7 metres of the boundary opposite the rear wall.

• Permitted development rights do not apply in listed buildings or designated areas.

Do I need my neighbours’ permission for an extension?

Well the reality is, sometimes, neighbours just don’t get along. With several individuals living in close proximity, it’s little surprise they tend to get on one another’s nerves from time to time. However, there’s a difference between having a tiff and being able to transform your house the way you want without having to obtain your neighbour’s approval.

The short and simple answer to this question is, not necessarily. However, you must first educate yourself by thinking about your extension and how it affects the houses around you. We’d strongly recommend you talk proposals through with your neighbour so as to avoid possible conflicts later. There are a number of reasons why your neighbour can protest to your new home extension plans. Let’s take a look!

 

  • In the event whereby your new extension is blocking their view or providing an unwanted shade on their property. Here, they have a legitimate reason to protest as no one would want their once sunny garden suddenly covered or plummet into shade.
  • In the event where it leads to a loss of privacy. For instance, if your new extension possesses a window which overlooks the neighbour’s property in any way. This is likely to be taken as an invasion of privacy and that has a little to no chance of being a welcomed idea.
  • If it’s a major project and going to take a lot of weeks before completion. The noise generated, especially when your neighbours are enjoying your summer holidays or weekends, can make their gardens not as relaxing as it used to be.
how much is a double house extension?

A double house extension is basically a construction to any aspect of your house that elevates up to offer two floors of space. It can be structured to suit your existing home in two storeys or as a side wing on a taller property. If you’re considering building a double house extension, then estimating the cost is a very important task to do before commencing the project. In this article, we’ll give you an idea of the cost of a double house extension so you can estimate yours accordingly.

The double house extension cost depends on several factors that’s specific to your home as well as your design choice. These includes:

• Location of your property. Places like London and the southeast will generally cost more than the other regions due to higher demands.

• Accessibility of the site. The ease of your site’s accessibility also plays a key role in the price.

• Size of the extension. The more the extension’s size in footprint and square metres, the higher the possible costs.

• Materials used in making the roof as well as the complexity of the roof design.

• Your choice of finishing. These includes flooring window and door frames, glazing, underfloor heating and roof lights.

• Your property’s soil type. Different types of soil requires varying treatments as well as materials to develop solid foundations.

Constructing a double house extension is a quite simple build in terms of technicality when its to the side or rear of your house as this can also help you save some money. Generally, considerably expanding your home’s space by building a double house extension will cost within the range of £1,500 per m2 to about £2,800 per m2.

Can I extend the front of my house?

When it comes to extending a home, the rear of the house often comes to mind a lot more than the front. However, this doesn’t mean that you can’t extend the front of your house. This can be done either as part of a renovation project whereby the entire house is incorporated or it can also be done in isolation. It’s possible to extend the front of your house without the need to apply for a planning permission, however, there are a bunch of limitations you’d have to comply with if you wish to carry out with such a project. Sometimes, this may imply that extending to the front of your home is more tedious and tasking than extending your home’s rear. So exactly how far can you extend the front of your home without planning permission?

 

The short and simple answer to this question is 2 metres square area with a height not more than 3 metres. Generally, you do not need a planning permission to build a front porch as long as its area doesn’t go beyond 2 square metres from a public road or walkway. Also, a tiled or slated roof can be as much as 4 metres but other roofs must not go beyond 3 metres in height. If you want to extend the front of your home beyond the restrictions specified, then you’ll have to apply for a planning permission.

 

Extending the front of home can be quite costly, but this can be controlled by not building to the extension to the highest specification, not including an extension on kitchens or bathrooms and more.
