ᐅ Offer for a Single-Family Detached House / Urban Villa

Hello dear homebuilding forum,

we are planning to build our single-family house in Saxony-Anhalt in 2018. Yesterday we received the offer. Could you possibly give us some feedback on whether it is good or rather not so good.

Thank you very much

The price is reasonable, in my opinion. However, all additional construction-related costs are missing, as you only have the house price.

Two things: You will have underfloor heating, so your towel radiator should be equipped with an electric heating element. Otherwise, it will warm up very little.

You don’t have a ventilation system included. Is that intentional? It’s better to choose a gas heating system plus controlled residential ventilation instead of building with a heat pump without a ventilation system.

Hello Pinno84,

So, that is only 1062€/m² (99 USD/ft²), which is never enough. On average, prices discussed here in the forum range from 1500-1800€/m² (140-167 USD/ft²). And you are far from that. For example, the term “loose rock” caught my attention regarding the deep drilling; just think about what you would find at depths of 50+ meters (164+ feet). It definitely won’t be Baltic Sea sand. Solid rock is much easier to drill anyway. You really need to be careful with this.

If they build it for that price... add another 100,000 (110,000) buffer and 30,000 (33,000) additional costs.

As for meeting the energy-saving regulations even remotely, let alone operating a heat pump economically, only they seem to know how.

Thank you for the responses.
We are aware of the additional costs and estimate them at 130K for site development (road, water, sewage, electricity, and lifting station), outdoor facilities, and kitchen, on top of the offer.
We will not choose a ground source heat pump until it has paid off compared to a condensing boiler.
We will decide on solar thermal and a condensing boiler.

The energy-saving regulations are not an issue with this brick. The price is reasonable. The extras are expensive, so try to avoid as many as possible. For example, the towel radiator alone costs over 500 gross. Our plumber charged 150 for it.
