Hello,
we want to build a KfW 40 plus house with a prefab home provider that has not yet been decided. Some elements, such as the photovoltaic system including storage, the prefabricated basement, the garage, the staircase, and possibly a few other items will be outsourced because it simply makes more sense.
Now to the actual process (after purchasing the plot).
1. Should we look for an architect/energy consultant ourselves, or does the architect from the prefab home company take over this role even if the basement, photovoltaic system, etc. are ordered externally?
2. Should we find an expert to simply support us during the construction? For this, should we rather choose someone from a home builders’ association or someone like a "prefab home expert"?
3. Obtain quotes from the prefab home companies, the basement builders, the photovoltaic installer, etc. For this purpose, I have already created a checklist to ensure that not too many additional costs appear during selection but that everything is included in the initial offer (otherwise it would be hard to compare). Of course, we will carry out a preliminary selection to be absolutely sure. What is a sensible order here? For example: prefab home provider first, then basement builder, then photovoltaic company, then exterior work, then staircase builder?
4. Decision on the prefab home company and revision or extension of the contracts such as the scope of work through additional clauses and everything that is not fairly balanced.
5. Then price negotiation. Should professional help be sought here as well and, if so, who? Would that person also be involved during the process?
6. Signature and starting signal for construction. The architect should have the floor plans, etc. ready before that for the building permit / planning permission application.
It would be great to get lots of input here so we are better prepared! Many thanks in advance!

But I didn’t want to end up with €100,000 of unplanned expenses after the final selection.You decide yourself how much extra the upgrade choices will cost. Set aside a budget reserve for upgrades and spend it as you make your selections. You can do some online research on the items to be chosen, so you get an idea of the prices.
Even if the company lets you browse the selection catalogs now, you won’t know what the prices will be in a year. They only provide rough estimates, which you can also find on your own.
Honestly, I don’t understand all the stress. Plan a reserve, set priorities, make decisions, and pay.
I don’t understand your concern about the customization process... We gathered quite accurate information through online research, questions at the show home of our building company, and finally from the details in the contract (which you receive some time before signing). This helped us know exactly where we wanted to customize and where we were likely to accept something without extra cost or only minimal additional charges. In the end, it worked out well, and the additional costs themselves weren’t unreasonably high, in our opinion, so we were comfortable with them. If someone is expecting €100,000 (about $110,000) in extra costs during customization, they are definitely looking at the wrong price range for general contractors / main builders.

It also depends on the company. With Viebrockhaus, you spend less on upgrades than with Team Massivhaus.

The selection process is meant to choose this, that, and the other. Generally, changing selections later is more cost-effective than upgrading them initially. If you have already upgraded certain options, you should only downgrade or remove others to avoid excessive costs. If you basically want an A4, it’s best to get it directly from Audi, because if you go to Seat and upgrade the Leon to an A4 level, it will unfortunately cost as much as an A6 (if not as much as an S6). If you want a frameless glass shower and large tiles, then the corner window has to be sacrificed. Confusing downgrading Bemustern with upgrading Aufmustern is regularly penalized with very high costs.
