Construction consulting: an independent construction consultant at your side

A construction consultant (Bauberater) is an independent expert who accompanies clients through the entire building project. They review construction and purchase contracts, monitor the build quality during the individual construction phases, document defects, support the handover inspection and advise on costs, technology and energy standards. Independence is key: a genuine construction consultant works solely in your interest and is not connected to the construction company.

The costs depend on the scope of services. In 2026, an orientation meeting costs around €100 to 200, a construction contract review about €400 to 900. Construction-accompanying quality control over the entire project runs at around €1,800 to 3,500 depending on the number of appointments. Hourly rates of independent construction consultants are usually between €90 and 150. Measured against the build sum, these are small amounts that can prevent expensive construction defects.

Independent construction consulting is particularly useful at three points: before signing the contract (reviewing the construction contract and services specification), during the construction phase (construction-accompanying quality control to detect defects early) and at the handover inspection (professional review and documentation before you accept the work). Anyone who only discovers defects after moving in has a much harder time legally and financially.

A reputable construction consultant is expressly independent, meaning: they have no economic connection to the construction company, the developer or tradespeople and receive no commissions from them. Only in this way can they represent your interests alone. Points of contact for independent advice include the Association of Private Builders (Verband Privater Bauherren, VPB) and the Builders' Protection Association (Bauherren-Schutzbund). Look for corresponding credentials and a clear fee agreement.

An architect plans and designs your house and can take over site management — they are involved in the building project itself. An independent construction consultant or building surveyor, by contrast, does not plan but neutrally monitors quality, reviews contracts and documents defects on behalf of the client. With a turnkey (schlüsselfertig) prefab house, where the provider plans and builds, an independent construction consultant is particularly valuable as a monitoring body.

Yes. Especially with a turnkey prefab house, the execution lies entirely with the provider — an independent construction consultant is then your only neutral monitoring body. They check the construction and services specification for hidden gaps, oversee critical trades such as the foundation slab, insulation and building services, and secure your position at handover. The consulting costs are usually small compared with possible costs of remedying defects.

Among the best-known independent points of contact are the Association of Private Builders (VPB) and the Builders' Protection Association (Bauherren-Schutzbund). Both refer sworn or qualified building experts, offer contract reviews and construction-accompanying monitoring, and publish guides for clients. In addition, the consumer advice centres (Verbraucherzentralen) advise on financing and contracts. Before commissioning, check qualifications, references and the fee model.
