Does A Single Storey Extension Add Value To Your House?

When you’re looking to construct a single storey extension or perhaps you’re just searching for means to increase the value of your property, this question always pops up. The short and simple answer to this question is a resounding yes, a single storey extension can go a long way to increase the value of your property. Just like any other home improvement, when done right, adding a little extra living space is one of the top things you can probably think of that’ll provide a cool increase in your property’s value. However, before you rush in you must also take note of some factors so you can be certain a single storey extension is the right option for you. These factors include the quality of the build, complexity of the build, cost of the build versus the value gain, ceiling price in the area, finance costs as well as the inconveniences and stress.

Generally, the average cost of a single storey extension can range from £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. So it’s important to know the value they’ll add to your house before deciding to make such an investment.

The value added to your property will depend largely on the quality and size of your single storey extension. The value is usually calculated by estate agents using the number of bedrooms, bathrooms as well as the floor area. Inside London, it’ll typically be priced at £5,000 to £10,000 per square metre, while outside London should be within the range of £900 to £2,000 per square metre.

how much is a ground floor extension?

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.

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.

For example, a kitchen diner extension that’s small and basic is likely to cost about £1,300 to £1,500 per square metre.
