Why choose Avenir Renovations?
Why renovate a garage?
1. Improve insulation and comfort
Garages built before 2000 are often poorly insulated or unheated. The result: a feeling of cold, humidity, heat loss to the house. Renovation allows you to:
- Insulate the walls, the roof, and the floor
- Limit thermal bridges
- Improve year-round usability comfort
2. Gain functionality
Do you want to transform your garage into an optimized storage space, a workshop, a gym, or a living space (office, bedroom, studio)? Renovation allows for a complete rethink of the volumes, electricity, lighting, and access.
3. Enhance your property value
A well-maintained, healthy, and insulated garage is a strong selling point. It is a highly sought-after practical asset in urban or suburban areas where parking is limited.
4. Respond to new uses
- Fit-out for electric vehicles
- Integration of a laundry space
- Creation of an interior access to the house
- Transformation into a professional or independent space

Frequent garage renovation scenarios
Renovating a garage can meet very different needs, ranging from simple refurbishment to complete transformation into a livable or multifunctional space. Here are the most common cases encountered by our clients in Belgium:
This scenario concerns an old, unheated, and poorly ventilated garage, often relegated to temporary storage use. Common symptoms include: cold walls, bare concrete floor, musty smell, and even mold.
Our solution:
- Installation of thermal insulation on the walls, ceiling, and garage door
- Installation of a single-flow ventilation system or an extractor fan
- Painting the floor with a waterproof resin
- Adding outlets, LED lighting, and supplementary heating
Goal: to transform this space into a healthy and functional garage, comfortable for parking or DIY.
More and more households want to create a clean and practical laundry room in their garage. This scenario requires reorganizing the volumes and optimizing the networks (water, electricity, drainage).
Our solution:
- Creating a laundry corner on tiled flooring, with a waterproof wall
- Adding connections for washing machine, dryer, and sink
- Installing closed storage (shelves, high cabinets)
- Insulating the ceiling (often under living spaces)
Result: a clean, organized, insulated garage, where it is pleasant to move around daily.
Very common in urban areas where space is limited, this project involves completely transforming the garage into a heated, insulated, and fitted space. This applies to a home office, guest room, independent studio, or rental accommodation.
Our solution :
- Replacing the garage door with a glass door or insulated wall
- Complete insulation (floor, walls, ceiling)
- Partitioning, electrical installation, plumbing, and heating
- Creating windows or skylights
- Installing decorative finishes: tiles, flooring, paint
This scenario sometimes requires planning permission, especially if the facade or use of the building is modified. We assist each client with regulatory procedures if needed.
In some recent or semi-recent homes, the garage is functional but outdated or poorly suited to new uses (electric vehicle, digital tools, home sports...).
Our solution :
- Bringing the electrical installation up to standard
- Installing a motorized and secure garage door
- Adding a reinforced socket for electric vehicle charging
- Aesthetic renovation: painting, floor tiling, stretched ceiling
- Integrating custom storage solutions
This type of renovation allows for enhancing an existing space without transforming it and increasing daily comfort.
Many homeowners want to connect the garage directly to the house (entrance hall, kitchen, pantry...) to avoid going outside, especially in winter.
Our solution :
- Creating an opening in the load-bearing or non-load-bearing wall
- Installing a fireproof or insulated door
- Leveling the floor if necessary
- Reinforcing acoustic and thermal insulation at the junction point
This requires a prior structural analysis and coordination with the existing configuration, but greatly improves daily comfort.
