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.

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).

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.

How to find a builder for a house extension?

Builders are everywhere, but finding one for your project can be tricky and stressful, with both cost and reliability coming into question. This is even more worrisome when you’re fully aware that your house extension can only be as good as the builder. If you’re also facing the same challenge, then you’ve come to the right place. In this article, we’ll share with you some tips on how to choose a professional and reliable builder who’ll ensure you get immense value for every penny spent. Let’s take a look!

✓ Ask for recommendations. To find a tradesperson, not just a builder, personal recommendations is the best way to go. 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.
