House Extension
What is the Cheapest Type of House Extension?

There are different types of extensions available and you’ll be glad to know that they don’t cost as much as you might think. You can choose from a single storey extension, a bump out, or a masonry construction. Read on to find out more about these options.

Bump out

If you’re looking for the cheapest type of house extension ideas, a bump out addition might be the way to go. A bump out addition requires no foundation work, and can save you as much as 15 percent on construction costs over a traditional addition. And unlike other types of extensions, it allows you to tuck the new room under the roof. This option is especially useful in areas with a lot of overhang, since extending the existing roof over the bump out is much cheaper than designing and building a new roof.

However, you must be sure that you choose a design that matches the existing aesthetic of the room you’re adding on. A bump out may require you to replace the original wallpaper or paint the walls to match. You may have to pay around $2 to $6 per square foot for paint and wallpaper, depending on the size of the room.

Sliding doors

If you’re looking to add space to your home without sacrificing on style, then sliding doors are for you. They allow light into your home and provide a wow factor for potential buyers. Sliding doors have been around for decades, and they are an excellent option if you want a great view from your home and lots of natural light. Sliding doors can cover a large area of your home and are usually fully glazed.

When choosing a sliding door, you must ensure that it’s easy to use. The price of these doors is the same and folding doors, although the price can be significantly higher if you want them to be very wide. Similarly, large sliding doors with single units of glass are very expensive and you should ask for several quotes before making your decision.

Masonry construction

As building a house extension is an intricate process, estimating the cost can be challenging. The best way to get a ballpark figure is to ask a qualified build professional to provide you with a quote. A general contractor can provide you with a comprehensive quote that will include the cost of materials and the amount of labor required to complete the project.

The cost of a house extension will vary depending on the material used, size of the expansion, renovations, and fixtures and fittings. If you plan to build a wet area, this will add to the cost per square. However, if you have no need for plumbing, tiling, or cabinetry, you can cut costs by excluding those elements from your plans.

Using reclaimed materials

One of the most sustainable forms of extension is using reclaimed materials. It not only makes economic sense but it is also environmentally friendly. Reclaimed materials are great for DIY projects and can be used for decks, fences, flooring, and even furniture. Using reclaimed wood can save you a fortune as compared to purchasing new timber, and can be as cheap as $5 per square foot.


Another way to cut costs is by avoiding building in unusual shapes, such as a hip roof or curved roof. These types of extensions take more time and labor to build and can be expensive. In addition, you will need to arrange the work of different trades. You will also have to deal with planning permission and building regulations, which will add to the cost.
