Even with a general contractor, you can seriously get burned despite the price guarantee. No idea why architects are always spoken of so badly here in general. I simply assume that a general contractor calculates a profit margin of maybe 5-10%. The price guarantee will currently certainly come with an increased risk surcharge, so you will quickly be over 10%. And we have repeatedly witnessed here in the forum how consistent these price guarantees were during Corona and the strong increase in building material prices. An architect who offers service phases 1-8 will probably not cost significantly more than the margin of the general contractor. A good architect can, if both sides want it, plan a house as cost-effectively as possible, create a clever spatial concept, and also influence the construction process individually. He acts in the interest of the client and not in the interest of a company. I don’t want to speak out against general contractors, but as long as you don’t get the “artist” you mentioned on board, the idea of considering an architect should not be discarded.

In my opinion, a combination of architect and BU would be the best solution. With an architect, you often have the problem that the price suddenly is much higher than expected. I would, if we were to build again, use an architect up to the building application, and afterwards a BU. That way you have, in the best case, a nice floor plan (architect) combined with a fixed price and construction time guarantee (BU).

I don't know where you are building, but about 2500€/m² is quite a reasonable value. If the general contractor makes a good impression, then take him.

It's already cheap for clinker, KfW 40. Just don't let yourself be sold a 4 kWp photovoltaic system and 3 kW, as is often the case, to achieve KfW 40. Besides, experience shows that the follow-up / final offer won't be any cheaper.

€70,000 for a double garage and incidental construction costs could also be a bit tight. Of course, a lot depends on the soil survey or soil quality when the earthworks begin.

I consider the idea of saving money by doing without an architect’s planning to be the decidedly more romantic notion. The kind of architects who cause the trauma of are in the minority. There are many good ones, and I am also happy to help personally in finding them.


Yes, and what I find most crucial is that the architect, especially as a construction manager (Google spoiler: "About construction managers and ... construction managers"), acts in the interest of the builder and not the company: where the architect-as-construction-manager pays attention to avoiding mistakes themselves, the task of the GC’s construction manager is more to avoid the mistakes being noticed before acceptance.

Switching to the draftsman after the architect’s service phase 4 can only be topped by doing so already after service phase 3 or planning completely only with the draftsman (unless: you build without any ifs and buts a proven catalog house 1:1). The romantic reduction of the architect to just a floor plan designer is probably one of the strongest cornerstones of the misjudgment that architects carry out planning tasks overpriced.

Firm binding price commitments can also be obtained by leaving the tendering to the professional (instead of falling into the delusion that the tendering is a good opportunity to do your own work - asking for prices, after all, any fool can do that). Nowhere in construction is as much money thrown out the window as in the amateurish, inexperienced chase for the supposedly fairest price.

By the way, a decision in favor of the architect route is NOT a decision against execution by a general contractor: a good architect will always allow bidders to offer to execute several or all lots as a package as a GC.

I don’t quite understand . Why should it be problematic to create a floor plan with the architect and apply for the building permit, then switch to a general contractor? They can also only build according to the plan, so they implement what was previously planned. But with them, I have the advantage of the construction time and fixed price guarantee, which is not given with the architect.
