Price estimate for house renovation in Belgium

What is the average cost of home renovation in Belgium?

Renovation prices vary according to many factors: property size, initial condition, site accessibility, choice of materials, technical constraints... That said, it is possible to classify renovation projects into three main categories, with price ranges per m² generally observed in Belgium.

Price table according to the type of renovation

Price of a light home renovation

A light renovation generally concerns houses that are still habitable but need updating. It is mainly an aesthetic project, without structural or heavy technical work. This may include:

• The refreshing of wall and ceiling paints

• The replacement of floor coverings (laminate, tiles, vinyl)

• The installation of new interior doors or baseboards

• The renovation of certain decorative elements (stairs, lighting fixtures, handles)

Indicative range: between 300 € and 600 € including VAT/m²
Ideal for a recent or well-maintained property requiring a simple refresh.

Price of an intermediate home renovation

This type of project is more common when purchasing an older house in decent condition but not up to current standards. This is referred to as a partial renovation, which may include:

• The updating of the bathroom or kitchen

• The replacement of exterior joinery (frames, doors, windows)

• The modification or creation of partitions

• The installation of new coverings (floors, walls, tiles)

• A partial update to electrical standards

Indicative range: between 700 € and 1,100 € including VAT/m²
A good balance between cost and value enhancement for an older property to modernize.

Price of a complete home renovation

A complete renovation is often necessary for older houses that have been uninhabited for several years, or for ambitious overall transformation projects. This involves all trades intervention, with structural and technical work:

• Complete overhaul of electricity and plumbing

• Thermal insulation (walls, attics, floors)

• Replacement or renovation of the roof

• Heating system (boiler, heat pump, radiators)

• Redistribution of interior spaces, modification of the structure

• Creation or complete modernization of bathrooms, kitchen, etc.

Indicative range: between 1,200 € and 2,000 € including VAT/m²
This budget can increase if technical, urban planning, or heritage constraints are added.
