Your questions about the AKENA extension kit
-
What are the advantages of an L-shaped extension for my property?
-
An L-shaped house extension is a type of architectural enlargement that adds a new space to the existing structure, arranged to form the letter ‘L’. This addition is usually attached to one side or the back of the house. This configuration offers several advantages, from optimisation of space to flexibility of layout.
- Optimisation of space: an L-shaped extension allows for the efficient use of unused areas around the house, such as corners or spaces between existing buildings. This offers the opportunity to enlarge the surface area of one's home without encroaching too much on the garden or outdoor areas.
- Great flexibility of layout: the L-shaped extension lends itself to many configurations, and can accommodate a wide variety of rooms, according to your needs and desires: spacious kitchen, cosy living room, bedroom, play area for children, office... Let your imagination run wild!
- More natural light: with well-planned openings, such as windows and glass doors, the L-shaped extension can considerably increase the amount of natural light in the house, making the spaces brighter and more welcoming.
- Improved living comfort: by gaining more living space, you also gain in living comfort. The L-shaped extension allows you to create a space dedicated to your leisure activities, to separate living areas for more privacy, or to welcome friends or family with complete peace of mind.
- An increase in property value: a well-designed L-shaped extension built by a qualified professional such as AKENA is a major asset for your property. It generally increases the value of your property, which can be an interesting argument if you plan to sell your house in the future.
- A harmonious architectural style: the L-shaped house extension can blend in perfectly with the existing architecture of your house, using the same materials, the same colours or the same style. It can also create an interesting contrast for a more modern or original effect.
- An economical solution: compared to other enlargement options or moving to a larger house, the L-shaped extension can be a more economical solution to obtain the necessary additional space.
-
When is it advisable to prioritise this extension configuration?
-
The L-shaped extension is particularly recommended in certain specific situations due to its flexible layout and numerous advantages.
Complex or narrow plot
If your property has unused areas or irregular plot configurations, an L-shaped extension can help optimise this space. This shape allows you to make the most of the available area, adapting perfectly to corner configurations or narrow plots.
Need to preserve outdoor space
For owners who value their garden or outdoor space and do not want to sacrifice it, the L-shaped extension offers the opportunity to enlarge the living area while minimising the impact on these areas. This allows you to keep your green spaces and your pool area.
Improved connectivity with the outdoors
The L-shaped extension maximises the amount of natural light depending on the orientation of your land. The two branches of the building offer multiple possibilities for creating openings and glazed doors, thus promoting a bright interior that is directly connected to your garden.
Increased privacy in the case of overlooking
In situations where it is necessary to add useful space while maintaining privacy from neighbours, the L-shaped extension can be strategically positioned to act as a buffer or a visual barrier.
To give a modern architectural style
The L-shaped extension can be integrated harmoniously into various architectural styles, from traditional houses to more modern constructions. It can also be used to create an aesthetic contrast with the house, by adopting a different look or using different materials.
-
Which room should be included in an L-shaped enlargement?
-
The L-shaped extension offers a unique opportunity to create interesting spaces that can take advantage of this distinctive angular configuration. This option can be used to design dynamic and multifunctional spaces, optimising each segment to meet specific needs while maintaining a coherent aesthetic that is integrated into the existing structure.
Here are a few layout ideas:
- An open-plan kitchen with dining area: use one arm of the ‘L’ to create a spacious kitchen, and the other for a dining area or small living room. This creates an open and airy living space, ideal for family and social interaction.
- A corner living room: create a cosy living room in the corner of the ‘L’, perhaps with windows on two sides for maximum natural light. This can become a main relaxation area with a breathtaking view of the garden.
- A master suite: place the bedroom in one section of the ‘L’, and a dressing room or en-suite bathroom on the other side.
- A multimedia space and library: configure one arm of the ‘L’ as a place of entertainment with audiovisual equipment, and the other arm as a quiet library. This forms a multifunctional family leisure complex.
- An art studio or workshop with storage: one arm can be used as a space for painting or creative projects, while the other can be used to store supplies and finished or unfinished works.
- A games room with storage space: use one side for noisy and fun activities, and the other for storing games, toys and sports equipment. This keeps the room organised and functional.
- A fitness room with relaxation area: dedicated to health and well-being, one part of the ‘L’ can contain gym equipment, and the other can be a prioritised area for yoga, meditation or simply for relaxing after training.
-
How can we plan to optimise living space?
-
Optimising the living space in an L-shaped house extension must be done strategically in order to make the most of this unique configuration.
Here are a few tips for planning the layout in such a way as to maximise space and functionality in this type of enlargement:
- Plan for functional zoning: use each arm of the ‘L’ for specific purposes that complement or contrast. For example, if one wing is dedicated to noisy activities such as a playroom, the other could be a quieter space, such as an office or library.
- Think about how to partition the different spaces: design open areas that can be used for different activities, such as a lounge/dining area or a workspace/library. You can also install movable partitions to adapt the space to your needs.
- Maximise the entry of natural light: choose large openings on two sides of the extension to make the most of natural light. At AKENA, we even offer to incorporate skylights in the roof to optimise the lighting in the rooms. Another little tip: choose light colours for the walls and ceiling to reflect the light.
- Make the most of the corners: take advantage of the angles created by the L-shape to install custom-made furniture or clever storage solutions. Don't hesitate to install wall shelves to save floor space.
- Ensure aesthetic consistency with the existing: use materials and colours that harmonise with your home. Play with volumes and heights to create a smooth transition between the old and the new. Finally, don't hesitate to install sliding doors or glazed doors to facilitate movement between the two spaces.
- Consider insulation and energy efficiency: make sure that the extension is well insulated and energy efficient. At AKENA, our models are designed to provide you with a pleasant living space all year round. Numerous pieces of equipment, such as roller shutters, sunbreakers and integrated LED lighting, can further improve the comfort of your enlargement.
-
Which materials should be favoured for the construction of an L-shaped structure?
-
When planning your L-shaped house extension project, it is essential to choose materials that are aesthetic, functional and robust. Aluminium and glass are popular solutions for this.
Aluminium for the structure of the extension
Aluminium is a popular material for building house enlargements. Indeed, it is known for its resistance to the elements. It does not rust, and is not affected by corrosion. This makes it an ideal choice for all weather conditions.
At AKENA, we also favour aluminium constructions because of its lightness, which makes it easy to shape and adapt to complex designs. It is available in a variety of different colours and styles. This material is therefore perfect for customised structures such as L-shaped extensions.
In addition, this metal requires little maintenance, often only occasional cleaning to maintain its appearance. It is also recyclable, making it an environmentally friendly choice.
Finally, aluminium can be combined with wood to give your structure a warmer feel. This allows the aesthetic qualities of modern, smooth metal to be combined with the natural texture of wood. The result is a dynamic front that can harmonise with a variety of architectural styles, from the most traditional to the most contemporary.
Glass to bring in more light
Glass, on the other hand, allows an abundance of natural light, illuminating the interior of the extension and creating a feeling of open, airy space. It offers a clean, contemporary appearance that can dramatically complement modern architectural styles. At your AKENA extension specialist, our high-performance glass can help maintain comfortable temperatures, reducing the need for heating and air conditioning.
Of course, the large panes provide unobstructed views of the outdoors, which is particularly valuable for properties with elegant gardens or attractive landscapes. Finally, glass can be used in a variety of ways, including in windows, doors, partitions and even roofs, offering numerous design options.
Using aluminium and glass together in an L-shaped extension can maximise the advantages of each material. This combination is ideal for those who want a modern enlargement that incorporates transparent and luminous design elements while being durable and low-maintenance.
-
How to choose an L-shaped extension that matches your style?
-
Opting for an L-shaped extension that harmonises with the look of your property is essential for creating a coherent and aesthetically pleasing space.
- Analyse the existing architectural style: start by understanding the distinctive characteristics of your current home. Is it modern or traditional in style? Note elements such as roof shape, building materials, window types and decorative details.
- Choose compatible materials: select materials that complement or match those used in your main house. For example, with aluminium, you could opt for a modern, sleek look that harmonises well with existing elements. If your home has wooden details, aluminium can even imitate their appearance with special finishes.
- Consider the colour scheme: make sure that the exterior and interior colours of the extension align with those of the existing house. Using a harmonious colour scheme will help to integrate the structure seamlessly. Here too, aluminium offers great flexibility in terms of finishes and colours, and can be powder coated in a wide range of shades.
- Respect the roof and finishing details: the roof is often a distinctive feature of a house. Choose a roof style and materials that harmonise with the existing building. Similarly, pay attention to details such as gutters, roof edges and ornaments. At AKENA, you can customise the roof with cornices and other decorations.
- Plan the landscaping: landscaping can play a crucial role in integrating an extension to the existing structure. Plan the planting, paths and exterior features to complement the architecture of the enlargement and the main house.
-
What regulations must be complied with for the L-shaped extension to his house?
-
To create an L-shaped extension to your residence, several local and national regulations must be complied with to ensure the legality and safety of the project. These regulations will vary from country to country across Europe, so it's important to consult with local authorities to ensure full compliance with the relevant laws and guidelines.
-
What is the price of an L-shaped house enlargement?
-
The cost of a L-shaped house extension can vary depending on several factors, including the surface area added, the materials used, the complexity of the design, the region where you live, and the labour required.
- For a customised house extension: allow between €900 and €3,200 per square metre.
- For an aluminium extension with wooden finishes: between €2,000 and €3,000 per square metre.
- For a glass extension: between €1,800 and €2,200 per square metre.
