Why renovate a villa in Leuven?
An envelope to bring up to standard
Four facades mean twice as many exterior walls as a terraced house of the same size. Without insulation, each of them loses heat. In a single-storey villa, the roof also covers the entire living area: this is where a significant amount of heat escapes.
That's why the EPC label of these houses is often modest, even when they have been well maintained. The potential for improvement is all the greater.
Volumes designed for another life
Closed kitchen, sunken living room, bedrooms at the end of a long hallway, attached double garage: villas from that era were designed around entertaining and the car. Today, we want a large living space open to the garden and quiet work areas.
The space is there. It needs to be redistributed.
A heritage to protect
In a Leuven market where villas with gardens are sought after, a complete renovation protects the value of the property and prevents it from being sold as a house to be rebuilt.
A renovated villa also retains its garden and original layout, two advantages that a new construction on the same plot would not necessarily have under current urban planning rules.

The benefits of villa renovation with Avenir Renovations
Avenir Renovations supports you in the complete renovation of your villa with rigorous organization. Each intervention preserves its character while improving your comfort.
In a villa, the order of work is crucial. A roadmap is established that starts with the envelope, then follows with techniques and finishes, with a budget item by item.
This plan takes into account the four facades, the roof, the garden, and the annexes: nothing is renovated in isolation without considering the effect on the rest.
Roofer, facade worker, carpenter, heating engineer, electrician, tiler, painter: a single Project Manager oversees everything, with a shared schedule and online tracking. Over several months, this continuity avoids information loss between phases.
Bricks, roofs, large windows: we keep what gives the house its charm and modernize the rest. A villa from the seventies can gain in comfort without losing the generosity of its volumes or the design of its facades.
Fixed quote, amendments only at your request, ten-year warranty. Payments follow the actual progress of the project, step by step, and each phase ends with a check with you before moving on to the next.
What is the price of a villa renovation in Leuven?
Surface area, starting condition, and scope of the program determine the budget. VAT inclusive estimates calculated at the reduced rate of 6% (building over ten years old).
| Type of work | Factors affecting the price | Indicative price VAT included |
| Facade insulation from the outside (4 facade villa) | Facade area, finish, scaffolding | 35,000 to 70,000 € |
| Roof insulation and refurbishment | Area, covering, insulation technique | 25,000 to 60,000 € |
| Replacement of all frames | Number and size of windows, material | 20,000 to 45,000 € |
| Heat pump with underfloor heating or suitable radiators | Power, emitters, possible geothermal | 18,000 to 35,000 € |
| Complete ground floor reconfiguration | Load-bearing walls, kitchen, finishes | 60,000 to 140,000 € |
| Renovation of surroundings (driveway, terrace, gate) | Surfaces, materials, automation | 15,000 to 45,000 € |
| Global renovation (envelope, techniques, interior) | Starting condition, level of finish | 1,100 to 1,800 € / m² |
The visit is conducted facade by facade: condition of walls and joints, frames, roof, floor, heating installation. You then receive a quote by lot, with the expected effect of each measure on the label.
Example: for a villa from 1972 in Heverlee, with one hundred sixty square meters of living space, a complete energy renovation with roof, facades, frames, and heat pump often ranges between 120,000 and 180,000 euros VAT included, before interior fit-outs.
Steps and grants for renovating a villa in Leuven in 2026
Engaging an architect and the permit
An interior fit-out that does not affect the structure can be done without an architect. For external insulation on the street side, an extension or a change of volume, an omgevingsvergunning and an architect are generally required.
For a villa, these works are often grouped into a single file, simplifying the process and ensuring overall coherence.
Grants for a renovated villa
A four-facade villa has a lot of surfaces to insulate, making the grants interesting. Since March 2026, Mijn VerbouwPremie still covers insulation, glazing, and heat pumps for income categories 3 and 4, and only heat pumps for categories 1 and 2. The VAT rate of 6% applies to works in a dwelling over ten years old.
Asbestos and period materials
Sixties and seventies villas sometimes contain asbestos in roofing sheets, ducts, or certain adhesives. The asbestos certificate provided at purchase indicates what has been identified. Removal is planned before any demolition, by a specialized company when quantities require it.
Organizing a villa renovation
Living in the villa during the work or not
A renovation of the envelope can be done while continuing to live in the house. A complete interior renovation, including electricity, floors, and bathrooms, is much simpler and often quicker in an empty house.
The duration of a complete villa renovation
For a major renovation, expect six to twelve months of work depending on the scope of the project, plus preparation and any necessary procedures. The envelope generally takes three to four months, while the interior and technical work takes the remaining time.
Insulation from the outside or injection of hollow walls
Injection is quick and economical, but it depends on the width of the cavity and the condition of the bricks. External insulation is more effective and changes the appearance of the villa. The choice is made after inspecting the walls.
Spreading the renovation over several years
This is possible, provided that a logical order is followed: roof and envelope first, then technical work and interior fit-outs. A written roadmap prevents undoing what has already been done.
Frequently asked questions about villa renovation in Leuven
Should a 1970s villa be renovated or demolished?
In most cases, renovation is more interesting: the structure is sound, the garden and layout are preserved, and the procedures are simpler than a reconstruction. Demolition is justified mainly when the structure is too degraded or the layout is no longer suitable.
Should the boiler be replaced before or after insulation?
Ideally after, to size the new heating for a house that has become less energy-consuming. If the boiler fails beforehand, a hybrid heat pump or a temporary solution avoids paying for an oversized installation.
What EPC label can a renovated villa achieve?
With a well-insulated roof and facades, efficient frames, a heat pump, and ventilation, a 1970s villa can often improve from an E or F label to a B label. With solar panels added, an A label may sometimes be achievable, depending on the orientation and compactness of the house.
Can a villa be divided into two dwellings?
Creating a second dwelling requires an omgevingsvergunning and must comply with municipal regulations regarding the number and size of dwellings. The municipalities in the south of Leuven and the City itself are attentive to these divisions. Feasibility is checked before any project.
A renovation planned over two seasons
For a villa, it is often wise to carry out the envelope in the nice season, then the interior and technical work during autumn and winter. This way, a roof and a heated house are maintained during the cold months.
