Find extension construction projects

High demand for expanding spaces without moving

In light of the rising real estate prices in Belgium and the increased comfort needs of households, requests for the construction of extensions are multiplying. Whether it is to add a living room, create a master suite, enlarge a kitchen, or build a home office, many contractors are looking for reliable and available professionals.

On ArtiBox, you can tap into this growing demand. You receive concrete construction projects for extensions in your region, in Brussels, Wallonia, and surrounding areas. You choose the construction sites suited to your skills and organization, without wasting time on prospecting.

Gain visibility without commercial prospecting

Building an extension involves many trades, good coordination, and a high level of trust from the client. But too often, tradespeople struggle to make themselves known. ArtiBox helps you showcase your expertise to contractors who are already actively searching.

Thanks to our platform, you gain visibility on extension and enlargement projects: you are informed in real-time of new requests, you have access to all useful information (area, desired materials, deadline...), and you can apply in just a few clicks via the mobile app.

Highly diversified extension projects

The construction of extensions can take many forms depending on the client's desires, technical constraints, or legal framework. On ArtiBox, you will find various construction sites in this field, covering all types.

Single-storey lateral extension

This type of project generally concerns an additional room attached to the existing house, often on the garden side.

• Construction on block or poured concrete foundations
• Brickwork or timber frame
• Flat roof with waterproofing and insulation
• Integration of large windows or high-performance frames

These projects often require good coordination with an architect and compliance with local urban planning regulations.

Roof elevation or raising

More technical, this type of intervention allows for the creation of an additional floor without encroaching on the land.

• Removal of the existing roof
• Creation of a load-bearing floor
• Raising walls or installing a timber frame
• New roofing with integration of roof windows

These are complex projects where the professional must master structure, insulation, and waterproofing.

Independent extension or garden studio

These construction sites are becoming increasingly popular in suburban areas or in the countryside.

• Construction of an independent module for office, bedroom, or workshop use
• Connections to networks and high-performance insulation
• Architectural integration into the existing environment
• Sometimes built with prefabricated wooden framing

They are often valued for their quick execution and limited impact on the existing structure.

Garage or existing space transformation

Rather than building new, some projects involve transforming an existing space.

• Complete insulation (floor, walls, roof)
• Replacement of the garage door with a frame
• Compliance with electrical and sanitary standards
• Interior finishes for habitable use

This allows for optimization of the existing space while controlling the overall budget.

Master urban planning rules

This is a true differentiating factor compared to less structured companies.
