Dear forum,
My wife and I—both complete beginners when it comes to building—are planning to build our dream home. We are still at the very beginning of the project and do not yet have a plot of land.
We recently had a very positive initial conversation with our preferred home builder. We want to build a timber-framed house in the Cologne/Bonn area. However, the builder is based in Lower Saxony. He told us that for locations farther away (like ours), he would not deliver a fully finished house but rather a shell home, with the remaining trades (electrical, plumbing, screed/flooring, painting) subcontracted locally. Since he cannot be on site regularly for supervision and coordination due to the distance, this approach seemed reasonable.
I see the option to manage the subcontracting of the trades myself as an opportunity to save costs because I can choose which company gets the job. My question to you is: as a layperson, surely it’s not feasible to handle the tendering and especially the supervision of the work on my own; this must be done by a professional, right? How do I go about this? Is a general contractor what’s needed at this stage? I imagine hiring someone who manages the tendering and supervision of the remaining trades for me. How would I find such a person? Or is there a different recommended approach?
I appreciate all your advice and tips.
Best regards from the Rhineland!

For these planning and supervision services, an architect is typically hired. The architect also represents your interests when enforcing quality standards and warranty claims in case of construction defects or damage. They formally accept the construction work as free of defects (formal acceptance), verify the work quantitatively (measurement, billing), and review the contractors’ invoices. Unlike a general contractor (GC) or contractors directly hired by you, this provides an independent level of control.
In addition to thorough structural and detailed planning, it is important to prepare tender documents listing the scope of work. This task requires expertise and special tendering software to create the specifications. Based on standardized tender documents, comparable bids from tradespeople can then be obtained.
If desired, the architect can also pre-plan and coordinate owner-performed work, both technically and organizationally. Time and cost management are other important areas covered by a professional project planner.
I assume your desired timber-frame house consists of an outer, visible timber frame for aesthetics, combined with an inner solid construction for the structural and energy-efficient building envelope. The provider’s system should be carefully examined in detail (scope of work description, component assemblies, building physics documentation for sound, moisture, and thermal protection) since this construction method is quite complex and must be thoughtfully designed to remain durable and free of damage.
From my experience with “authentic” old timber frames, timber frame renovations, and occasionally with new timber-frame houses in construction consulting, I am familiar with several critical issues that should be checked with today’s suppliers.
Where would you ideally like to build? Are you primarily interested in the timber-frame appearance or the “wood house” construction method? The latter is nowadays typically implemented as timber frame, panelized timber, or timber skeleton construction, featuring prefabrication, short construction times, and a dry construction site.
