How to Renovate Your Apartment in Lille?

Renovating an apartment, much like in a house, is a lengthy and complicated project, depending on the condition of your real estate assets. Here are the essential steps to successfully complete your project in Lille.

Define and Prepare the Apartment Renovation Project in Lille

Firstly, you need to start by defining and specifying the objectives of your project. This allows you to have a clear idea of ​​establishing the budget forecast and analyzing the feasibility of the work.

What type of renovation do you want to bring to your property in Lille? You can distinguish three options, depending on the characteristics of your real estate. Light renovation or simple refreshment and maintenance of the apartment only consider the floor, ceiling, and walls. The work specifically involves:

      • Installation and refurbishment of floor covering (tiles or parquet),

      • Sanding or varnishing the floor in a room,

      • Wallpapering as a wall covering,

      • Repainting the wall and ceiling.

    Partial renovation, as the name suggests, involves renovating part of your apartment, one or two rooms, your bathroom, and kitchen, for example. This project can serve two purposes: improving the energy performance of the property and optimizing its interior layout. Furthermore, if your budget allows, total renovation is recommended, especially if you have just purchased your apartment and intend to rent it out. This type of project aims to completely refurbish your property and involves, among other things, extension, layout, electrical installation, and changing the heating system.

    To access the building's characteristics and thus define the appropriate type of renovation, do not hesitate to take stock. Take the time to check the heating, ventilation, electrical installation, plumbing network, floor, wall, ceiling, and facade of your apartment.

    Furthermore, preparing your renovation project necessarily involves planning the work. Make sure to organize them in a coherent manner and in order of priority.

    Renovation of the Structural Work in an Apartment in Lille

    In construction, the structural work refers to all the work that ensures the solidity and stability of the building. It concerns, in particular, the walls and floors, the roof, the terrace, the balcony, and the openings (doors and windows). The renovation of these elements must be carried out delicately.

    Various projects can take place to renovate the structural work in an apartment, as in a house in Lille. Strengthening the foundations of the construction is important if you are considering a lateral extension or removal of a load-bearing wall. This work is also necessary in case of subsidence of your floor. This, whether it is made of wood, concrete, or steel, requires special maintenance. As soon as you notice damage related to the load-bearing floor of your accommodation, consider immediately replacing it to ensure that it does not affect the solidity of the building.

    Renovation of the structural work involves replacing windows if you find them in poor condition. This is also the case if you want to improve the insulation of your accommodation or bring more light into your home. In terms of interior design, it may sometimes be necessary to demolish a load-bearing wall to make more space for the layout. Since this operation directly affects the building structure, such an operation requires the intervention of several trades (architect, masonry company, plumber...).

    Furthermore, concerning the roof of the building, its renovation is necessary as soon as it undergoes water leakage, poor insulation, or when converting the attic. In this regard, you may need to replace it. Facade renovation is also a significant work item as soon as activities on the structural work in a building or house are involved. Similarly, you are encouraged to regularly maintain or change, if necessary, your drainage system to comply with the standards imposed in Lille.

    Renovation of Second Work in Your Apartment in Lille

    When it comes to renovating an apartment or a house, there are numerous second work tasks involved.

    Insulation Work in an Apartment in Lille

    Unlike renovating a detached house, insulation in an apartment is typically done from the interior. In a building, it's rare to insulate the facade and the roof.

    To enhance thermal and acoustic comfort in your interior, insulating windows is essential. Single glazing, often found in older houses or buildings, accounts for 10% to 15% of heat loss in a home. It's also a point of entry for external noise or noise leaving your interior. To address these issues, consider replacing it with double glazing with enhanced insulation while ensuring its sealing.

    Retrofitting the insulation of your interior wall also improves the energy and acoustic comfort in your apartment or house. You have three options for this: insulation with metal framing, bonded doubling, and air gap insulation.

    Ceiling insulation is also an effective solution to combat noise disturbances caused by neighbors' footsteps, for example. Additionally, it's crucial for retaining heat in your apartment. Installing a false ceiling is a highly effective renovation solution to better insulate this part of your property. Similarly, you should consider insulating the floor to keep your interior comfortable. In this regard, you can install insulation under the concrete slab or on the joists and battens for wooden flooring.

    Plumbing Renovation

    In an apartment or a house, plumbing refers to all work related to :

        • water distribution and drainage,

        • hot water production,

        • gas supply,

        • sanitary appliances, and plumbing fixtures.

      The plumbing network consists of a complex system of pipes, tubes, valves, faucets, and pumps at various installation points.

      Plumbing works go hand in hand with kitchen renovation. Indeed, the latter often requires a modification of the plumbing installation, especially if you're considering a new layout. The same goes for bathroom renovation in your apartment in Lille.

      Renovation of Various Installations

      Second work renovations also involve installation and troubleshooting of the electrical system. This entails improving various connections of the network and replacing, if necessary, the meter, circuit breakers, contactors, sockets, and switches.

      You also need to renovate the ventilation system in your interior to ensure better air circulation. In this regard, installing a Mechanical Controlled Ventilation (MCV) system is a high-performance solution that combines comfort and energy efficiency in your interior.

      Renovation of Heating System and Hot Water Production

      Replacing, installing, or troubleshooting the heating system is part of the second work. In this regard, consider replacing your existing equipment with more efficient, environmentally friendly, and economical devices. Specifically, it's recommended to use innovative and environmentally friendly devices, such as a wood boiler, condensing boiler, heat pump, or a Combined Solar System (CSS).

      Regarding hot water production, renewable energy-based devices, such as a thermodynamic water heater or solar water heater, are preferable.

          • plumbing, electrical, and ventilation installation or troubleshooting,

          • laying new flooring and wall coverings,

          • installing cabinets, countertops, and appliances,

          • and installing a backsplash on the kitchen wall.

        Just like the kitchen, the bathroom is also a crucial wet area in your apartment. Its renovation should be undertaken delicately to make it more appealing, especially if your property is intended for rental purposes.

        In principle, interior bathroom renovation aims to facilitate its maintenance, control humidity to preserve the decor, prevent accidents resulting from the cohabitation of water and electricity, etc. To ensure your bath is a true moment of relaxation, several steps are necessary, including plumbing and electrical installation or troubleshooting, changing floor and wall coverings, installing furniture, and decoration (lighting and painting).

        Interior Apartment Layout

This project involves, first and foremost, clearing unnecessary items to make room for arranging your belongings. Declutter the passageways to facilitate movement in your accommodation.
