Aspects that effect Single Storey Extension Prices

There are a few variables to remember when you are setting your budget plan. The major aspects that affect the price of a single storey extension are the dimension as well as the coating. However there are other variables that it deserves remembering while you are making your plans.

Pricy Groundworks Needed

If it is hard to dig the foundations as well as lay the footing for your extension, then this can enhance the cost of your extensions. This could be the instance if the ground is difficult to work with. Particles in the ground can additionally raise the costs.

  • Grade of Fixtures and also Fitting
    After the dimension of the extension, the following largest variable is the quality of the surface. Choosing premium alternatives can lead to the final rate being greater than double what it would be when choosing the standard alternatives.
  • Size of Extension
    When you are getting an extension on your residence, the single greatest variable that will certainly affect the cost of your extension is the size of it. The bigger the extension is, the much more you will certainly wind up paying. If the area inside the extension is basic, without inner wall surfaces, after that this will reduce the cost per m2 somewhat. Nonetheless, despite this in mind. The bigger the area of your extension, the a lot more you pay.
  • Type of Extension
    The sort of extension you choose will certainly go a long way in the direction of determining how huge your extension will certainly be. Side return extensions produce the smallest additional space so are typically the cheapest choice, while a wraparound cooking area extension will create one of the most space as well as have one of the most over-priced fittings and also fixtures.
  • Building Regulations
    Most of the times, building regulations do not include a great deal of cost to a building task. Nevertheless, if you are developing an extension onto an older residence, there might be some unexpected prices. This is especially real if the house has not just recently been updated. Structure guidelines will relate to your entire house, not simply the extension. This can bring about the demand for electrics to be considered or door changed.

FAQs

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.

does a kitchen extension add value to your house?

If you’re planning to add a kitchen extension to your property or perhaps you’re simply looking for ways to increase the value of your property, this is one of the common questions that usually pops up. A simple answer to this question is yes, a kitchen extension will add value to your house. With a kitchen being one of the most frequently used room in a house, adding an extra space to the commonly used room can only increase the value of the entire property. However, to determine the value added by such an extension, there’s a need to calculate the cost of setting one up first.

Kitchen extension costs are greatly influenced by a wide range of variables such as the size, type of the extension and specifications, your location, professional fees, materials used and more. Overall, the type of the extension you opt for will play the most significant role in the determination of your kitchen extension cost. Here, we’ll be looking at a single storey kitchen extension.

For a single storey kitchen extension, you can expect your home’s market value to increase within the range of 5 percent to about 10 percent. When trying to calculate the cost of kitchen extension, it’s crucial to take into account how much value it’ll add to your home so as to make sure that the amount expended will not outweigh the expected value to be added by the project.

For a more accurate idea, there’s the need to consult local estate agents. However, for a much needed guideline, single storey kitchen extensions are usually able to add about 5 to 10 percent to a home’s value, while double storey extension should be up to 20 percent. But as stated earlier, this will depend on several variables.

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.
