Costs for a single-family house in the Hanover area (approx. 155 sqm)

Hello everyone,

I am new here, but I have been thinking about building a house for some time. I now have two specific questions regarding the financial framework. First, the following:

We are currently considering buying a building plot (600 sqm) near Hanover.

On it, we would like to build a solid single-family house with 150 - 160 sqm of living space, two stories with a normal gable roof, basic dimensions about 12 x 8.5 meters. Preferably with a basement; if this is not possible for cost reasons, a converted attic is the alternative. Additionally, a normal garage, preferably with access to the house. The single-family house should be faced with brick and preferably have two additional gables, each slightly projecting (about 0.75 m to 1 m). We envision 3 bathrooms (a small guest WC, a children's bathroom with shower, and another bathroom with shower and tub for us).

We have so far received a cost calculation for an Effizienzhaus 55 from a solid house provider (Baumeisterhause Tadge). This amounts to 300T € including garage (9K €), outdoor facilities (7K € - seems low to me), fireplace (12K € for chimney plus the fireplace itself), incidental costs (25K €), pellet heating and solar system for hot water (21.5K €), electric shutters — without basement, with converted attic. The calculation also includes all painting, sanitary, and electrical work, as well as floor coverings.

1.: Is this realistic?
2.: What would be a realistic figure for our above-mentioned wishes if I have everything designed by an independent architect and built by a construction company?

Thank you very much for your information, suggestions, or tips!

I now have very rough calculations for a similar property, 145 sqm. One architect says 300K € is possible without land, the other says 340K €. But the latter calculated with much higher additional costs.

does that mean the house construction itself would be significantly cheaper? what exactly was included in the additional costs?

Hello,

regarding point 2: I am thinking about that option. So if it is realistic to have a corresponding house designed by a freelance architect and built by a construction company for €300K (including the flooring, building services, etc.) – and that’s how I understand your answer, please correct me if I misunderstood – then I would definitely prefer this option.

No, you understood correctly

one more question: aren’t the €7K indicated in the calculation for the outdoor facilities a bit too little?

I want to answer from the gut: if it concerns the driveway to the garage, the price is in my opinion about right.

Kind regards

that means the house construction itself would be much cheaper? what was included in the additional costs?

140 sqm
230,000 € house
15,000 € garage
15,000 € outdoor facilities
30,000 € additional costs
