Building a new house involves choosing between two models of site organization: entrusting the project to an online platform that coordinates the trades, or assembling a network of local artisans yourself. The choice is based on specific criteria, and the differences between these two approaches are more pronounced than one might assume regarding contractual responsibility, site monitoring, and dispute management.
Contractual Responsibility: Who Bears the Risk in Case of Defects in a New House?
This is the most significant point of divergence, and one that most comparisons overlook. Since 2024, some platforms no longer just connect parties: they sign the contract directly with the client and subcontract to artisans. The individual then has a single point of contact in case of disputes or defects.

With independently recruited local artisans, each trade (masonry, carpentry, plumbing) is subject to a separate contract. If a defect appears at the junction of two trades, it is necessary to identify the responsible party among several professionals, which prolongs resolution times.
| Criterion | Contracting Platform | Independent Local Artisans |
|---|---|---|
| Contract Signatory | The platform (single point of contact) | Each artisan separately |
| Recourse in Case of Defects | Against the platform | Against the artisan of the relevant trade |
| Coordination of Trades | Managed by the platform | Responsibility of the project owner |
| Transparency of Reviews | Regulated by the DSA since 2024 | Word of mouth, manual verification |
| Site Monitoring | Integrated digital tools | On-site meetings, direct exchanges |
| Flexibility During Construction | Limited by the contractual framework | Direct negotiation with the artisan |
This table highlights a clear trade-off: legal security on one side, operational flexibility on the other. For a new house, where there are many trades and frequent technical interfaces, the question of responsibility weighs heavily in the decision.

Transparency Obligations of Platforms: What the Regulatory Framework Changes
The transposition of the Digital Services Act and provisions from the Naegelen law have changed the rules of the game for matchmaking platforms in the construction sector. Two obligations deserve particular attention for a construction project.
- Clarification of the Platform’s Role: it must indicate whether it acts as a mere intermediary or as a party to the contract. This distinction determines who assumes the ten-year warranty vis-à-vis the client.
- Combating Fake Reviews: the criteria for ranking professionals and the methods for verifying reviews must be explained. A local artisan recommended by word of mouth does not go through this filter, making verification more informal.
- Enhanced Pre-Contractual Information: the individual must receive a detailed description of the services, guarantees, and termination conditions before signing.
For a new house project, these obligations provide a measurable safety net. However, they do not guarantee the quality of execution on the ground, which remains tied to the competence of the engaged artisan.
Site Monitoring and Responsiveness: Online Platform vs. Local Artisan
The construction of a new house spans several months. During this period, unforeseen events (delays in material delivery, plan modifications, bad weather) require constant responsiveness.
A local artisan located near the site can intervene quickly for adjustments. The direct relationship allows for discussions about material changes or technical adaptations without going through an intermediary. This flexibility diminishes as soon as a third party coordinates the site.
Platforms compensate with digital tools: real-time tracking, progress photos, centralized messaging. These features facilitate remote management, but they do not replace an on-site visit when a technical problem arises at the junction between two trades.
The Case of Modifications During Construction
Modifying a plan after work has started is common in new construction. With an independent artisan, an amendment to the quote is negotiated directly. On a contracting platform, any modification goes through the overall contractual framework, which can extend validation times and generate additional administrative costs.
Guarantees and Insurance: Check Before Signing the Quote
Regardless of the chosen model, three protections should be systematically checked for a new house:
- The ten-year warranty, mandatory for all construction professionals. On a contracting platform, it is the platform that must provide it. With independent artisans, each professional must produce their own certificate.
- The damage insurance, taken out by the project owner, which allows for pre-financing repairs without waiting for a court to designate the responsible party.
- The guarantee of perfect completion (one year after acceptance), which covers defects reported at delivery.
A platform that signs the contract centralizes these guarantees. With local artisans, the verification of each certificate falls to the individual. An oversight on a single trade can create a coverage gap that is difficult to fill after the site is accepted.
Quality of Referenced Professionals
Platforms generally display selection criteria (certifications, customer reviews, seniority). A local artisan not referenced on these platforms is not necessarily less competent, but the individual must conduct their own checks: registration in the trade register, RGE certifications if applicable, references from recent projects.
The choice between an online platform and local artisans for building a new house boils down to a trade-off between risk centralization and direct site control. The determining criterion remains the contractual status of the platform: simple intermediary or co-contractor. This distinction, reinforced by the regulatory framework since 2024, conditions the protection of the project owner throughout the duration of the legal guarantees.
