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 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.

There are some additional costs you may also need to factor in to your extension budget. These includes surveys, architect fees, planning application fee (if needed), insurance and Party Wall Agreement (if needed).

how much does a kitchen diner extension cost?

If you’re planning to construct a kitchen diner extension, to help you set a budget and start planning you must first have a cost estimate that’ll complete the entire project. If not, there’s a probability that you may have to spend more than would have been necessary or probably break the bank to have the project done. In truth, there’s no single and short answer to this question as the cost of a kitchen diner is largely dependent of several variables. In this article, we’re going to give a good insight into kitchen diner extension cost so as to help you make informed decisions moving forward. Let’s take a look!

On the average, a kitchen diner extension will cost within the range of £25,000 to about £45,000, however if you happen to reside in London, you can expect the cost to be a lot more than that - closer to £60,000. And due to the fact that there happens to be a plethora of options out there, any decision to make be it on the size, tradesman, flooring, finishes or type of the kitchen diner extension, will have a considerable impact on the overall cost of the project. For instance, a basic kitchen diner extension cost can be within the range of £12,000 to about £15,000., while a high end kitchen diner extension can reach a whooping price between £80,000 to about £100,000.

The total cost of your kitchen diner project will rely heavily of the size as well as the quality of the finishes. For example, a kitchen diner extension that’s small and basic is likely to cost about £1,300 to £1,500 per square metre. However, if you’re going for higher quality finishes, you can expect to pay within the range of £1,900 to about £3,000 per square metre.

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.
