Financing volume 410k € Feasibility assessment

137,000€ additional construction costs sounds a bit too much.

Oh sorry, I didn’t subtract the land portion :oops::rolleyes:

If I subtract the land, we have additional construction costs + outdoor facilities of about 70k.

So then a price per square meter of about 2440€.

Although we will probably have to add a bit more for the outdoor facilities.. We will probably end up at around 25xx per square meter in the end.

But of course, I can only report that once it is done and has to be paid.

Did you also consider extra costs for lighting and drywall? That came up for us, for example, during our kitchen planning...

We considered that during the kitchen/utility room planning and it will be done by the kitchen studio.

I understand that as individualized ancillary construction costs. These are inevitably higher than if you just add earthworks + house connection + construction power/construction water.

Are earthworks really ancillary construction costs? I rather count them as part of the house price.

We come in Brandenburg at:
- KFW 55 bungalow with 138 sqm + 12 sqm covered terrace + increase to 3m shell height.
- brine-water heat pump (horizontal collector loops) + tempering
- controlled residential ventilation with enthalpy heat exchanger
- fireplace
- electric shutters with central switch
- photovoltaic system with 13.29 kWp
- a few more upgrades.
at about €2,800 / sqm. Contract is about 1.5 years old. Prices apply until the end of construction.

Although we will certainly have to add a bit more for the outdoor facilities..

We took this into account in the kitchen/utility room planning and it is being done by the kitchen studio.

Thanks for the clarification: If I now simply replace 25xx with 2580, then you have €600/m2 for the ancillary building costs or €600/m2 * 153m2 = €91,800 ancillary building costs. With a construction contract of €300k, that is just under 30% of the contract sum as ancillary costs, so the rule of thumb that a builder told me about 4 years ago still seems to hold true. :)

It depends on what earthworks are described as in your construction contract. For us, that was only a fraction of the actual costs.

Are earthworks actually incidental construction costs? I rather count them towards the house price.

It depends on the construction company. Prefabricated house builders, for example, usually expect those to be done entirely by the client. Others assume a perfectly level plot and include removing 30cm of topsoil. My general contractor includes quite a bit and also handles the wastewater connections and cistern. When comparing square meter prices, you should reduce it to the house + foundation slab/basement and count the rest separately. That is relatively comparable across different houses. Earthworks, soil disposal, and connections depend heavily on the plot and the positioning of the house. With outdoor facilities, there is also the matter of taste. If desired, you can sink tens of thousands into the garden even on a perfectly level plot.

Are earthworks actually ancillary construction costs? I tend to include them in the house price.

Yes, they do concern the individual plot.
