How Much Do Brick Extensions Cost – 2021 Guide

How much do brick extensions cost? This is the most commonly asked question while planning a house extension. So, we’ve decided to cover everything you need to know about the cost of building house extensions in 2021!

The exact cost of brick extension can’t be estimated as it depends on numerous factors such as your location, extension type, contractor fee, legal permissions, etc. But that’s not why we are here, right? Here, we will tell you approximate figures you can expect your brick extension cost to have.

Single Storey Extension ( say 5m x 5m)

The average rates of single-story brick extensions range between £1,000-£1,200 per meter square. However, this was before 2020. Now, you should expect around £1,500 per meter square for a medium-range extension. Moreover, these figures will go up or down depending on the location of your house. So, for example, if you’re planning for a 5m x 5m extension, the build cost will be approximately £37,500 at the rate of £1,500 per meter square.

Further, add about 10 to 15 percent professional fees and VAT (£6000) on this value. So, overall, a single story extension would cost roughly around £49,124.

Double Storey Extension

  • The general rule of thumb is, the cost of a double-story extension is 50% more than the build cost of a single-story extension.
  • So, taking the above figures, i.e build cost £37,500 +50% = £56,250.
  • Again add 10 to 15 percent as professional fee and VAT of £9000.
  • The double-story extension cost will be roughly around £73,577.

What about kitchens and bathrooms?

For a bathroom, add around £5000. The cost will go up or down depending upon the facilities and finish you want in your bathroom. And for a kitchen, consider adding £10,000. Again, this cost will vary according to your requirements and specifications.

Things To Keep In Mind While Planning A House Extension

There are certain things that you should keep in mind while planning a brick extension. These will not only save your budget but will also make sure you’re getting the best possible results.

Select your architect carefully. This is the first and the most important thing to do. The right professional will help you to create a project as per your requirement while also maintaining the cost. On the other hand, a less experienced or dishonest architect will trick you into things for his own profits.

Don’t select the contractor who you think is the best in your area. Take help from your trusted architect and select multiple contractors. Research about them, ask for references, and then shortlist 3 to 5 builders. Get multiple quotes and select the best brickwork contractor.

Don’t fall for trends. This is where most homeowners fail. The thing is, trends come and go, and not every home is suitable for adopting the trends. Take guidance from your architect and consider the classic and durable designs rather than going for the latest fades.

This should be all. We hope our post helps you in making an informed decision.
