You have an attic on your house and you want to convert it into a bedroom. This is a great solution for expanding living space or having an extra bedroom to accommodate visiting loved ones. Nevertheless, this type of development represents major work which can be very expensive and which needs to be properly carried out in terms of implementation and compliance with the legislation in force. Let's take stock to see more clearly.
Converting the attic to make a bedroom and installing an extra bed is an excellent solution to gain more living space. On the other hand, this type of work cannot be done just anyhow. Here are the tips we recommend you follow to make your project a success.
As part of such a project, you will be subject to certain legal constraints and obligations:
The conversion of an attic to install a bedroom requires a very substantial budget. Indeed, it is estimated that for a light arrangement, it is necessary to count 500 to 900 euros per square meter, against 900 to 1,500 euros for a complete arrangement. Here are the different positions to consider and the average cost to predict.
The insulation of the attic is essential for the comfort of those who will sleep there and for that of the whole household living below. In addition, good insulation allows you to make significant savings in heating and air conditioning throughout the year, but also to avoid the development of mold. There are several ways to insulate attics. Insulating mattress, blown or laying cellulose, thermal screen, polyurethane foam… depending on the solution chosen, count 2 to 80 euros per square meter.
To this price should be added that of the installation which amounts to between 20 and 50 euros per square meter for interior insulation and between 100 and 130 euros per square meter for exterior insulation.
If the development of a bedroom in your attic requires the installation of wall partitions and ceilings, you will have to consider an additional budget. Count 10 to 50 euros per square meter on average.
As we have said, a staircase worthy of the name is much more comfortable for accessing an attic bedroom. Depending on the model chosen and the fittings to be planned, this item can cost between 500 and nearly 10,000 euros.
To avoid humidity and mold and to promote good air circulation, it is important to consider installing ventilation in the attic. There are attic fans, for an average budget of 500 euros, but they are only used to bring in fresh air. For a VMC, plan rather 700 to 1,500 euros.
The amount of the invoice will vary greatly depending on the installation envisaged. For a single room, the budget can be limited to around 1,000 to 1,500 euros. On the other hand, for a more specific installation or to attach a bathroom to it, plan at least 2,000 to 3,000 euros.
This budget will only be necessary if you plan to install a bathroom next to your bedroom in the attic, toilets or a simple water point. Count at least 1,000 euros for a simple installation and up to 10,000 euros for the complete installation of a bathroom adjoining the attic bedroom.
If you plan to install a heating and / or air conditioning system in your attic, this item can cost between 3,000 and more than 10,000 euros. It is difficult to mention a price, because this area is directly related to your installation in the rest of the house and to what you plan to implement in the attic. We therefore recommend that you seek quotes from professionals.
If you have the possibility of installing a roof window, it will be the best solution to properly ventilate the space and to bring in natural light. However, for this position, you will have to pay between 100 and 2,000 euros.
To decorate your bedroom in the attic, you will need to reserve a more or less substantial budget. For paint or wallpaper, count 15 to 100 euros per square meter depending on the choices made and the finishes envisaged.
For your floors, do not hesitate to invest in an insulating solution in acoustic and thermal terms. You will gain comfort in both directions. Depending on the coating chosen, count an average of 20 to 150 euros per square meter.
