ᐅ Looking for building plans for a multi-family house with 4 apartments and a penthouse

In the green area, you have one set up that (to be honest looks quite awkward) and represents about 120 sqm (1,292 sqft) per residential unit.

However, I find it sufficient to request quotes from home builders (whether solid construction or prefab, it doesn’t matter for a qualified cost estimate if it matches the desired building method exactly).

Yes, awkward is a good word; those were just the first ideas. Large rooms are important—I think nothing worse than people renting or buying condominiums and living in small cages. (personal opinion)

Quotations should be obtained from building material suppliers, gas, electrical, etc., and the plan mentioned above is not enough for that.

That’s why I’m asking in the forum if there are draftsmen/architects here who would sell such plans?

If you don’t give them the extra square meters, they won’t be grateful for your opinion.

But complete plans from others aren’t enough either. Nobody figures out from plans what exactly they need. They want to know how many cubic meters of masonry (for example) they should quote for.

I’m starting to understand: Your naive assumption is that the costs are the sum of all subcontracted individual trades. First of all, that’s far from the truth; secondly, you won’t get that information by looking at floor plans and sections.

What your drawing really is good for: finding out the total price if the entire house were built by an external contractor. Then in the second round, you ask again how much the price would be as a "shell and core" or "basic build," meaning with all self-performed trades excluded.

Trying to "save" on a tendering professional will cost you more in lessons learned than the value of your own residential unit.

Building plans are created according to the zoning plan, often referred to as the development plan.
If this is not available, there is no design.
Wrong forum, but primarily the wrong approach by a complete layperson.

P.S. 500,000.. no way.
And if your dad has ever worked in the construction industry, you should ask him about the proper procedures.

The shell construction costs for materials have been estimated at 400.00 € per m2 (430 sq ft), with labor costs excluded; labor would add about 60% more. The house will be built by family members, including the foundation slab. (Yes, family help still exists; all houses were built by mutual support. Polish roots and mentality are still present, which you rarely find among many Germans. That’s why construction is so expensive because labor costs drive everything up.)

With all due respect to our hardworking neighbors, but building a multi-family house like that is a whole different level compared to a typical single-family house.

But regardless, how much does land cost per square meter in your area?

Does that also have to be covered within the 500,000 budget?

And comments like “it can’t work without an architect, I don’t need one.” Father (a construction technician) used to be self-employed with his own construction company but due to age is no longer physically able, so he is supposed to manage the construction. He has not worked in the industry for 15 years but still has knowledge.

He should still know that you need someone authorized to submit the building permit / planning permission application. And as others have already said, a house, especially of that size, rarely fits exactly into an existing zoning plan.

That’s why you should consult an architect; you don’t have to use all their services.

By the way, I cannot imagine your floor plan at all.

Here’s the calculation:

4 × 100 m² (1,076 ft²) + 160 m² (1,722 ft²) = 560 m² (6,028 ft²)

Add to that €1,500 (please adjust for local costs)

By the way... Where do the residents park? Here, you would need at least 10 parking spaces. Given the size of the apartments, no one will settle for just a parking space or a carport. So, an underground garage would be necessary.

Oh, and a basement too…

So, add 200 m² (2,153 ft²) at €1,000

This already puts the total cost in the seven-figure range.

If you could save labor costs completely on the shell construction (without the roof)—let’s say 60% instead of 40% (which I don’t really believe)—then you might save around €250,000.

These €250,000 correspond to about 4,200 skilled worker hours. Considering the scale, let’s generously estimate 6,000 unskilled hours.

That equals 150 work weeks, full-time! Or 3 years straight, without breaks, vacations, or another full-time job.

Who is supposed to do this, and when? And who earns the income for daily living during that time?

And which bank finances €250,000 (about $275,000) of “personal contribution” in a project with a guaranteed seven-figure total volume?

Apparently, there isn’t even money for a planner. Or for a plot of land.

Nonsense.

Since we are contracting trades separately, you at least know the cost share of each trade for your own project... The shell construction is very important to a layperson, but if you look at the invoice... for us, it accounts for about 25% of the construction costs (excluding land), including earthworks, and about half of that may be labor.
