Single storey extensions are a great way to add space and value to your property. A single storey extension can be extremely affordable and they're appropriate for many homes. Smaller sized single storey home extensions can be built without the need to apply for planning permission as they are protected by permitted development rights. Large single storey extensions will still need planning permission. Single storey home extensions can also often be positioned to either the side or rear of your property. Single storey home extensions can be used to extend kitchens or to add a downstairs study or utility room.

 

Additionally, they are often used to create a larger open plan area in the downstairs of the property that may be used as a kitchen diner or living area. Adding roof lamps and bifold doors to your home extension will create a big airy space that provides a seamless transition in to the garden. While single storey home extensions may appear less complicated than other types of extension, careful planning remains required to make sure that the new space is functional and beautiful. Certified architects and contractors can give you advice on the most appropriate design for your home extension, taking into account the specifications of the new space as well as the best way to complement the present building. Your single storey home extension could be made to match your pre-existing property and use similar materials for its construction or be made to contrast, giving an impressive effect by using differing materials.

 

Factors that effect Single Storey Extension Costs

There are a few elements to bear in mind when you are establishing your budget plan. The major factors that influence the price of a single storey extension are the dimension and also the surface. However there are other factors that it deserves bearing in mind while you are making your strategies.

High-priced Groundworks Needed

If it is hard to dig the foundations as well as lay the ground for your extension, then this can increase the price of your extensions. This might be the case if the ground is difficult to collaborate with. Particles in the ground can also elevate the prices.

  • Grade of Fixtures and Fitting
    After the dimension of the extension, the next most significant variable is the caliber of the surface. Picking premium options can cause the final price being more than double what it would be when picking the basic choices.
  • Dimension of Extension
    When you are obtaining an extension on your residence, the single largest aspect that will affect the cost of your extension is the size of it. The larger the extension is, the a lot more you will wind up paying. If the area inside the extension is straightforward, without inner walls, then this will reduce the price per m2 slightly. However, despite having this in mind. The larger the location of your extension, the a lot more you pay.
  • Sort of Extension
    The sort of extension you pick will go a long way towards dictating just how huge your extension will certainly be. Side return extensions develop the tiniest extra space so are usually the most affordable alternative, while a wraparound kitchen area extension will certainly produce the most room as well as have one of the most pricy fittings and components.
  • Building Regulations
    For the most part, constructing regulations don't add a great deal of cost to a building job. Nevertheless, if you are building an extension onto an older home, there might be some unexpected costs. This is specifically real if the home has actually not recently been updated. Structure guidelines will put on your whole residence, not simply the extension. This can result in the demand for electrics to be looked at or door replaced.

 

Kitchen Extensions:

Kitchen extensions greatly come under the realms of single floor extensions, although all type of home extensions could be made use of to incorporate added space for a kitchen.

As an approximate overview, a single storey extension will cost from ₤ 1,000 - ₤ 2,000/ m2, with a standard build at the lower end of the scale and also an excellent construct high quality at the greater end at a variety, with costs of ₤ 2,500/ m2 plus.

how much does a kitchen extension cost?

Being the most used room in a house, it’s little surprise kitchen extension are usually one of the most popular requests in the UK. They do not only open up a frequently used space in your home, but also goes a long way to add value to your property. However, to know the value that’ll added you must first determine the cost of building such an extension before moving forward. Generally, a typical kitchen extension will cost within the range of £20,000 to about £50,000 plus VAT, based on the size of your project as well as your location.

In reality, a single accurate cost of a kitchen extension will vary depending on a lot of influencing factors, one of which is the type of the extension. Let’s take a look!

✓ Rear extension. You may want to consider this type, if you do not have sufficient space for a side return. This will extend your kitchen into your garden which implies that you’re going to give up some green space to make this a reality. The average price to have this done in London will be about £30,000 or more including VAT, and about £20,000 plus VAT or more in other areas.

✓ Side return extension. This, normally, isn’t a huge add to your property, but will create a lot of space for your kitchen while also be a lot reasonable in terms of cost. This type will extend your home into an alleyway at the side of your property if any is available there. On average, the cost of the side return extension should be about £50,000 plus VAT in London and a lot less in the other regions.

how much does a single storey house extension cost?

If you’re planning to build a single story house extension, this is one of the first questions that usually comes to mind to help you set a budget and start to make plans. But as simple as it seems, a single accurate answer can not be provided due to the fact that there are several variables that can play a key role in influencing the price of a single story house extension. These variables includes the size, location, design or specification as well as the build route. In this guide, we’ll provide you with a rough estimate that you can work with to put you on the right path.

The main determinant of the cost of a single storey extension is the size of the build, while the next most relevant factor is the quality of the finish you opt for. For a small extension, you can expect to spend a sum within the range of £14,000 to £17,000. Meanwhile for a larger single storey extension, if you opt for a large wrap around the extension with a great amount of glass to be incorporated in both the walls and roof, you can expect to pay a sum within the range of £80,000 to £120,000.

Overall, the average cost of a single story house extension is usually within the range of £34,000 to £37,000. For this price, you should get a standard sized rear or side extension which also includes the cost of a kitchen - it’s the most commonly use for a single story extension especially in the UK.

do i need planning permission for a kitchen extension?

If you’re planning to construct a kitchen extension on your property, one of the first things that comes to mind is whether or not you’ll require a planning permission before you proceed. Generally, kitchen extensions are normally classified as permitted development which allows you to carry out your project without any interruptions from the law or your local authority. In other words, if your extension is meets up with the guidelines of the permitted development rights, you won’t have to apply for a planning permission. However if otherwise, you’ll have to apply for a planning permission to your local council and may require additional reports. And regardless of your position, you’ll always need building regulations approval before you can carry out any kitchen extension project. It may also be required that you’ll have to issue a part wall notice if you’re to build on or close to the boundary with a neighbour.

If you don’t want to go through the hassle and stress involved in applying for a planning permission with your local council, then you must ensure the following:

✓ Your kitchen extension must not be over half of the area of land around your main house.

✓ The kitchen extension must not be side elevation onto a highway or forward of the principal elevation.

✓ The extension must not be taller than the highest part of the roof.

✓ The height of your kitchen extension must not go beyond four metres.

✓ Kitchen extension that’s more than one storey must not go exceed the rear wall of the main house by more than three metres.

✓ Two storey kitchen extensions must not be closer to rear boundary by anything less than seven metres.

✓ The kitchen extension must not include balconies, verandas or any raised platforms.
