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.

How to find a builder for a house extension?

Building a house extension is a major undertaking which comes with a lot of costs, so if you’re going to do it the least you can do is ensure you do it right. Carry out your research, ask friends and family, neighbours and loved ones if the know of any reliable builder in the local area.

How long does a small extension take?

If you’re planning to build a small extension on your property, you’ll most likely want to know the length of time it’ll take to complete the home extension. Just like many other home improvement projects, it’s impossible to provide a specific number of day in which your project will be completed as the duration is based on a number of influencing factors. This includes the size of the development work as well as whether or not you plan to live in the house when the work is being done. In this article, we’re going to give you a breakdown of the processes that’s involved in building a small single storey extension alongside the duration for each so you can have an idea of how long your small extension project will take. Let’s take a look!

✓ A small single storey extension will normally take about 3 months to be completed.

✓ Site preparation is the first step in the process and it’ll take up to 2 weeks the dig out the footings and prepare foundations. Followed by a further 2 weeks to fit the damp course as well as any drains required around the extension.

✓ The 5th week is spent on working on the external walls and putting in place blockwork to deliver cavity wall insulation.

✓ The next 2 weeks will be spent on installing the roof structure as well as internal walls.

✓ Once done. The builders will make the structure weather proof and electricians or gas fitters will be on site to add power to the extension. This will be followed by internal walls’ plastering as well as breaking into your main house.

✓ After this, when the plaster is dry and decoration completed, units or furniture will then be installed.

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.
