Help with the house floor plan, improvement suggestions?

Good evening,

The dimensions, as can be seen from the floor plans, are 7.77 x 11.39. It will be a KFW 55 house with an air-water heat pump, underfloor heating, and 9 KWp photovoltaic system. Roof overhangs + clinker. Together with applications, permits, toilet, electricity......... So really everything except painting work and floor coverings in the living rooms €260,000 and then you can see what can be done through own work

Sorry, it is already a bit late. Thank you for repeating the house dimensions.

I just tried to recalculate the selling price based on your information and come to a different value; a higher construction cost just for the house ... even with a double-shell masonry or prefabricated house, and I have not even taken the additional costs into account.

Therefore, I cannot imagine that your dream of homeownership can be realized at this price.

Rhenish regards

Hmm what do you get? This is a reputable provider, they also do many very large projects for us. I don't think they will cheat me. And it's a fixed price. I also have the construction description. The plot of land is of course additional. It's another 175€ per sqm. 618sqm plot. I don't know if I am allowed to mention company names here in the forum.

Hello,

Hmm, what result do you get? This is a reputable provider; they also do many large projects with us. I don’t believe they would cheat me. And it’s a fixed price. I also have the building description. The plot of land is of course additional. It’s another €175 per sqm. 618 sqm plot.

I always initially assume a conventionally – that is, solidly – constructed single-family house. Depending on which wall construction you prefer – filled bricks with 36.5 cm stone or also 42.5 cm aerated concrete – you achieve somewhere between 135 and 145 sqm/living area for KFW 55. Taking the average, i.e. 140 sqm/living area, I am already at your final price with a plastered building with a basement; the required stone for KfW 55 as well as the technology already cost more than KfW 70 and are reflected in the sales price. A double-shell masonry costs even more, as primarily a higher amount of craftsmen hours must be considered. In the first step, the inner shell is built, in the second the insulation, and finally the clinker.

The reputable prefab house provider does have it “easier” to realize KfW 55 in the wall construction, but their main focus is on the actual manufacture of the prefab house. Overall more expensive than a conventional solid house builder.

What both have in common is that the necessary drillings for the geothermal heat pump are difficult to calculate in advance. It may be sufficient to make 2 drillings totaling 100 m, but further drillings may also be required. A final exact monetary figure can only be determined once the corresponding report is available. The building description you have will surely also take this into account.

That I calculate typical additional construction costs at €35,000–40,000 is surely also known to you. Taken together, this makes me doubt that the fixed price will actually be sufficient.

I would really be interested; a part of NRW now belongs to my sales area and I always like to be well informed. Especially also because I evaluate construction documents and am therefore also dependent on verifiable experience from third parties. Please send me a private message with the name of your currently favored provider. Thanks!

When looking at the exterior views, you can also piece together the information.

What would surprise me a bit is that the houses have not been sold since April 2011.
Is the land price disproportionately high or is one tied to the involved bank?
If you suddenly pay 1% more interest because you are tied to the bank, then a cheap house price can quickly become a very expensive total price.

I don't know why the houses haven't been sold yet. You are basically tied to the developer. You can choose the bank yourself. You can change the size of the house but not the exterior appearance since the houses are already fully planned. The geothermal heat pump costs an additional €5000. But air-water is included in the price. The developer assured me that it is really a fixed price and nothing more will be added. You are making me a little uncertain. Do you think it is strange? In the construction description it says 17.5 Maierwerk made of perforated bricks Poroton or equivalent. thermal insulation composite system 16cm wlg 035. And triple glazing

What is definitely still coming are the ancillary acquisition costs such as the notary and property transfer tax. I am not familiar with the developer regarding how the selection of tiles, sanitary, electrical, doors, windows, etc. works. If that is still coming, I would plan at least another 10,000€ for that.
