Obtain comparable quotations from suppliers

It works for me. The main page of Stiftung Warentest consists of only 4 letters. So: The four letters, dot, then the domain ending, slash and "praxismappe-baubeschreibung". Maybe you made a typo? Maybe someone can confirm that it works for him/her? Unfortunately, the link cannot be found through the largest search provider. But it is mentioned in the book of the same name, from which I have benefited a lot.

I just opened it, it works without any problems ;)

People,

thank you very much for the tons of information!

As with my preliminary inquiry, I primarily did it to see what is even possible. I was allowed this for a pitched roof, which has a max. 100 m² footprint, is brick-faced, and gable-oriented.

At the time, I had basically requested the Viebrockhaus Maxime 300 with 146 m² living space for simplicity’s sake. 11.8 x 8.6 m footprint. Only with a changed room layout.

But fully basemented.

I was told in the decision that I may build this way or similarly (same look as permitted, brick-faced and same orientation, house may be smaller).
(The preliminary inquiry primarily clarified from the outset the buildability of the plot, less what may be built, because the development plan is fully adhered to except for the overbuilding of areas, including plot ratio, height, etc. It’s all sufficient.)

Now I have slightly reduced the house (to 10.25 m x 9 m) and adjusted the rooms. I will still upload my sketches for this, but in principle it is also supposed to become an Efficiency House 40. I still have to tidy up the drawings and create layouts, then I will present them here. I am now at 120 m² living space, still basemented.

If you’re okay with the general contractor: openly say that you want to decide only after the planning.
Ask what he charges for the planning if it ends after that.
Do it and pay.

Alternatively independent architect. 5 times as expensive and catastrophically annoying – result probably more individual and nicer.

That’s how I will approach it. I already thought so, but I first wanted to do some research before I set myself up as a noob in a faux pas. I also see the thing with the architect similarly after research.

My assessment is that currently the material prices financially dominate the whole project and the construction company and labor share are currently less significant. So I hope that wages do not significantly rise in the next few months....

Question:

It would of course be great if I could somehow lock in the costs given to me. But that probably won’t work, or can something like that be secured after all? No, right? (I mean, if I get an offer now for 400k and it should be 500k in 8 months, that would be very bitter, or I would then be left with a building ruin. That would then be another reason to continue to probe the used house market....

Best regards

That's how I will approach it. I already thought so too, but I wanted to do some research first before I embarrass myself as a complete newbie. After researching, I also see the matter with the architect similarly.

An architect is the choice if you want to build individually. It is neither more expensive nor cheaper than with a general contractor - but more individual and fitting.

Make your plans, but expect price deviations of 50-100% based on the plans since you are not making a concrete tender. So actually have it planned by a general contractor - but then you can no longer really compare well.

Of course it would be great if I could somehow lock in the costs that are mentioned to me. But that probably won't work, or can something like that be insured after all?

Construction contract with fixed price guarantee.

Word 4 and Word 5

I made a draft in Sketchup and a preliminary request was approved.

At the time I basically requested the Viebrockhaus Maxime 300 for simplicity with 146m² of living space. 11.8x8.6m footprint. Only with a changed room layout.

And you specially redrew the Maxime 300 in Sketchup?

The development plan is fully complied with except for overbuilding of areas,

So what now: complied with or not?

I still have to tidy up the drawings and create layouts,

Why not do it now first, the way you presented it to the building authority? - "Creating layouts" sounds like you’re fiddling with a gigapixel poster with all floor plans, views, etc. on a single wallpaper, which the other discussants first have to download by crane (?) - PLEASE NO!!!

And did you specially ketchup the Maxime 300?

Yes. Not exactly 1:1 but very similar. In terms of external dimensions, it should be something like the Maxime 300.

The building authority was primarily interested in the footprint and its position, as well as the style. I wanted to keep it as open as possible and as concrete as necessary.

So what now: complied with or not?

We are allowed, through the exemptions, to build as if the areas in the development plan were buildable. (The areas may be compensated elsewhere.) We comply with the requirements of the development plan.

Why not just now, as you presented it to the building authority?

See link above (Maxime 300). But the discussion about the Maxime 300 is pointless, so I will upload my adapted planning here shortly.

It’s really just about sketches. I haven’t planned anything exact, but I try to roughly hit the wall thicknesses and see where the fridge fits, etc. I hadn’t given any thought to that before.
