FAQs

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 is a ground floor extension?

Generally, extensions can be a very tricky undertaking - where it can be quite difficult to have a clear comprehension of the rules, regulations as well as costs. Therefore before you rush in to kick start your ground floor extension project, it’ll be wise to get a good grip on the cost. In this article, we’re going to give you a rough estimate of the cost of a ground floor extension. Let’s take a look!

Just like several other home improvement projects, the cost of constructing a ground floor extension is based on a number of things which includes the size, materials used, your location, the quality of the tradesmen or company hired and lots more. For instance, if you happen to reside in London, the cost of your ground floor extension is going to be a lot higher than the other regions.

The single cost of a ground floor extension should fall within the range of £1,500 per square metre to about £2,000 per square metre. However, if you happen to live in London or the South East, this price can reach up to £1,900 per square metre to about £2,400 per square metre. These prices are for good quality ground floor extensions only. Basic or low quality extensions would naturally cost less while superior quality extension will cost more.

Now looking at the size of the ground floor extension, if you’re looking for a size of about 5m x 5m, you can expect to pay a price within the range of £32,000 to about £36,000. And as usual, in London or the South East, this price can reach up to £50,000 or even more. And that’s just for constructing the extension. If the other relevant costs like the 10 percent to 15 percent professional fees for the architect, planning application (if needed), building regulations and more, the price goes up.

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 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.
