Price for extension and enlargement of house 20m2
Adding space to your home is a dream shared by many homeowners, but before taking action, it is essential to understand the costs involved in such a project. The extension of a house of 20 m² offers a significant surface area that can be used in various ways and, despite preconceived ideas, it is not necessarily as expensive as one might think! How can the price of a 20 m² extension be estimated according to the options chosen (materials, finishes, etc.)? What use can you put your house enlargement to? Our experts have the answers.
The right budget for your project
Your extension is like a new wing on your house; it should reflect your needs and your lifestyle. Opting for a 20 m² extension is an ideal way to add extra space while increasing the value of your property. This personalisation will naturally be reflected in the final cost, as each choice you make will affect the final budget. That's only natural! The key, however, is to find a balance between what you want and what is financially feasible.
In our opinion, several factors must be considered when establishing the cost of a 20 m² house extension:
- The surface area of your extension: why choose 20 m²? Because this area offers enough space to create an additional bedroom, a comfortable office, a playroom for the children or even a gym. It gives you the square metres you need to meet a specific requirement without unnecessarily burdening your budget.
- The building materials: these vary enormously in terms of their durability, appearance and availability in relation to your location. For example, the use of ecological or high-tech materials can increase the cost, but also the value and energy efficiency of your extension. This is the case with AKENA extensions in aluminium, one of the most popular materials on the market.
- The difficulty of the work: the cost of construction depends heavily on the accessibility of your land, but also on the type of soil on your plot (which is decisive for the definition of the foundations, for example). These elements will determine the ease with which we can build your extension module as well as the cost of the labour allocated to your project.
- The layout options, often more expensive: high-quality interior design is generally more expensive, but a good design can maximise the use of space and increase the functionality of your home extension, especially when it is small in size, such as 20 m². Elements such as integrated lighting, custom-made furniture or built-in storage can transform your extension into a truly unique and versatile space.
In any case, establishing the cost of a 20 m² home extension requires careful planning and thorough consideration of many factors. That's why we take care to support you during this stage, providing you with the keys to make a decision. By requesting a free quotation from our technicians, you can quickly get an idea of your project's budget and can then ensure that it is both feasible and in line with your aspirations. It's simple!
The aluminium extension or conservatory, for good value for money
Aluminium is a particularly good choice for a 20 m² extension, due to several of its remarkable properties. First of all, it is lightweight, which makes it easy to transport and install, while being extremely resistant to corrosion, thus guaranteeing a long service life for the structure. But that's not all! Aluminium can be designed and shaped in very contemporary styles, lending a modern and elegant aesthetic to any project. The modular aspect of aluminium construction is another major advantage, as it significantly reduces the time needed for construction and, consequently, the associated labour costs.
An additional (and not insignificant!) advantage of aluminium is its amazing ability to be customised to a very high degree. This customisation can include a variety of choices in terms of finishes, colours and textures, ensuring that each aluminium extension project is completely distinct and perfectly tailored to your desires. For example, we offer colours ranging from glossy white to frosted grey, including a very deep textured anthracite grey!

Example 1: extension of the AKENA showroom from €38,220
Let's take the concrete example of the AKENA living room extension. The owner wanted a 14 m² extension with a modern aesthetic that would blend in harmoniously with the existing structure. He opted for a living room extension, which would not only provide additional space for his interior, but would also offer a whole new living experience. The desire to innovate and stand out led the client to choose:
A rectangular roof that is both understated and elegant. The extension was built in the form of a flat roof, with a textured anthracite grey colour for a contemporary aesthetic that does not lack character.
Anthracite grey, the flagship colour of modern architecture, was chosen for its aesthetic qualities and its ability to blend with different styles. The chosen texture adds a subtle tactile dimension, while the designer cornices (DV2) elegantly balance the silhouette.
Finally, a flat ceiling equipped with LED spotlights guarantees a warm and even light, ideal for enjoying this new space at any time.
The implementation of such an extension requires meticulous planning and the intervention of qualified professionals. The price including VAT of €38,220 includes the measurement, manufacture in the Vendée and installation by teams experienced in this type of intervention. For this type of extension, the price per square metre is around €2,700.
Example 2: price of the enlargement of a 20 m² kitchen-type house
This 20 m² house extension is more expensive than the one mentioned above, but its price per m² is lower! With a flat roof characteristic of contemporary structures, the choice of graphite colour and a cornice with a minimalist design, the extension blends in harmoniously with the existing architecture.
It should be noted that the price of the extension includes high-quality equipment for a practical and pleasant kitchen. The roof is made up of free-standing sandwich panels with a double-sloped glass dome, offering pleasant natural light. The fronts are equipped with 4/20/4 double glazing with Low-E + Argon treatment for optimal thermal insulation! Finally, for perfect control of light and privacy, a wooden batten half-wall with integrated roller shutters is a discreet but effective solution. One thing is for sure, this 20 m² extension stands out! Its price: €60,684 including VAT.

What other layout should you give to your 20 m² construction? Bedroom, garage?
An additional space can completely transform the dynamics of your home. Here are a few ideas of what you can do with a 20 m² extension:
- Games room: to provide a place for children to play indoors, freeing up space in the main living area.
- Office: more and more people are working from home, a separate office can help with concentration.
- Guest bedroom: having a designated bedroom for guests is a luxury that can be greatly appreciated.
- Relaxation area: a small extension can be transformed into a reading room or a sunny dining area. At AKENA, we often build extensions known as ‘conservatories’, most of which are fully glazed. These extensions, which are more open to the outside, offer a very special atmosphere to enjoy on sunny summer days, for example!
