House extension
In order to add some style and some square meters to your house, planning extension work is the perfect way to go. Making a house bigger with an extension technique is the right way to gain space. Our extension & renovation company offers two different kinds of extension ; the first kind implies the creation of a lifting mechanism for your house (type 1), the second kind is a lateral extension of your house (type 2) with an additional hold on the ground Our renovation company « Concept Intérieur France » invites you to visit this website for an easier understanding of the technique, and for learning about the differences between those two types of extension.
« Concept Intérieur France » is an extension & renovation company with an expertise handed down from father to son since 1960. We guarantee quality, and a meticulous work. Are you in need of a garage ? a new bedroom? setting up a veranda ? expanding your living room with an extension ? Anything is possible !
The use of an extension technique allows to expand your house and to make most of your projects come true, while never having to move out.
Roof spaces can be converted, for they are often neglected or used as an attic. In order to convert one's roof spaces into a real floor, it's often necessary to proceed with a lifting mechanism extension. This slightly elevates your house, in order to dispose a real flat surface, ready to be created, furnished and decorated by our renovation company « Concept Intérieur France », expert in the field. This type of extension requires a construction license and some plans which can be realized by our 2 architects, Laura and Olivia.
A lifting mechanism extension begins by laying down the existing roof, the frames and the gutters too. Afterwards, our construction company realizes the masonry to raise the gables and the facades ; this will gain height on the sides. Then comes the framework construction phase, realized with wood or with steel ; later on, it is well-insulated with a multilayer film. Depending on your wish and on the construction permit, a roof is built, whether tile-covered, or with the usual zinc material.
Our renovation company also advises you on the type of ground to create for this new living floor. According to the level of comfort you desire, the chosen material can whether be an insulated wood, or a concrete slab.
Once the structure is done, we realize all the distributing walls, the plumbing, the electricity and all the completions like the bathroom and the flooring.
You want to extend your house by realizing some extension works, but you wonder which extension is adequate. Indeed, your needs are evolving every day, and sadly, your home doesn't fit you anymore. In the page dedicated to the type n°1 of house extension work, we have already clarified how to elevate your house, in order to convert the roof spaces.
Now we're going to talk about the type n°2 of house extension work. This is a lateral extension with an additional hold on the ground. However, your property must be big enough to support an additional construction.
Our renovation & extension company « Concept Intérieur France » has an expertise in all construction areas, in renovation, and in all types of construction or extension. Our knowledge has been handed down from father to son since 1960.
A lateral extension for your house allows you to gain some square meters lengthwise. For instance, it allows you to create a garage with an extra room on top, to build a veranda, or to create a separate studio.
Before starting this type of extension work, a permission to build is required. It will impose us a certain kind of construction materials, as wood, blocks made of glass or stones, a traditional zinc roof, or a tiled roof.
Benefits of a type 2 house extension
The benefit of this type of lateral extension is that your current house stays available throughout the work phase. This lateral extension allows you stay at home unlike the type n°1 of house extension work, for which a roof is removed, then installed.
Lateral extension works for your house allow you to demolish the wall of your living room, in order to integrate the extension inside. To compensate for the demolition of the bearing wall, our renovation company realizes a recovery of the structure and a metal assembly. Throughout the installation of the new roof, we can build a velux window or a big Sky Dome, to lighten your whole ground floor.
We can also incorporate a low-energy underfloor heating in the new concrete floor, which will be covered with parquet / tiles / waxed concrete, afterwards. Our company has the ability to create you a real garage. We can entirely equip it with gates, pits, pressurized air, etc...
Outside, we can install a driveway and an access ramp to the garage. If necessary, we can also change your initial gate motorization. We own all the assurances and guarantees required. Our expert company can achieve these extension works, from the house foundations until its last completions.

GORGEOUS ! A single word to sum up the achievements of Concept Interior France. Our little family can welcome guests again. Before the works, we could not even meet at 5 in the living room, the space was so confined. After removing the partition between our living room and the dining room, our apartment seems very spacious.

Many thanks to Concept Interior France!
I can only recommend the services of Concept Interior France. I have always been afraid to start renovation work after a bad experience during the construction of our house. But this team succeeded with flying colors in the work I asked for. My bathroom renovation is just such a success that I can't get enough of spending long hours in it!

Boris DIMITROFF's team is professional. I did not regret entrusting my extension work to the team of Mr DIMITROFF. I had some apprehensions when he offered me to go on an elevation to add a new bedroom to our house in Paris. But the result is simply harmonious.
Jane L.
Very good advice and satisfactory follow-up. The exchanges with them are quite fluid. Laura and Olivia are creative and give good advice. My villa in Nice has found a new lease of life. The team has managed to preserve the style with a touch of modernity. My favorite is the restoration of the stairs. I wanted to keep the style at all costs and the mission is successful!
Patrick M.
Finally a company that meets deadlines! The Concept Interior France team is attentive and above all very responsive. But above all, the deadline was respected. Yes, there were a few unforeseen events, but my son's studio renovations were completed in record time. Well done!
Lefebvre
A listening team
I received a few proposals before renovating my Haussmann apartment. I chose Concept Interior France because this company did not try to sell its services at all costs. Mr DIMITROFF is a listening advisor and clearly explains what is feasible or not. Trust came naturally and the choice was quickly made!
Catherine
If I had to do it again, I would always choose Concept Interior France. We had a very nice experience in the renovation of our house in the Yvelines. From the estimate to the end of the project, we were serene. The exchanges were carried out in a good mood while remaining professional. The result is in line with our expectations.

I recommend
If I have to sum up my experience in three words, it would be: Responsive, fast and efficient.
Good value for money. Carpentry completely redone. I always dreamed of having a modern kitchen in white, they did it! Being very picky in the details, I have no complaints about the quality of the work!
