Hello everyone,

I’d like to gather your experiences regarding plumbing for the construction of a new single-family or two-family house to better estimate and verify the costs.

First, a brief overview of our planned project:
Two-family house with timber frame construction
About 160sqm (1,722 sqft) of living space over two floors, no basement, separate technical room of around 12sqm (129 sqft)

Regarding heating and plumbing, the plan includes:
Two bathrooms measuring 12sqm (129 sqft) and 6sqm (65 sqft)
Air-to-water heat pump
Underfloor heating throughout the entire house
Central ventilation system

The quoted costs, including labor but excluding bathroom fixtures, are just under €80,000.
How do you assess these costs? Do you currently have similar projects and could provide some insight into your approximate expenses?

I’m a bit surprised, for example, to find the heat pump model about €3,500 cheaper online.
Also, the ventilation system at around €11,000 seems quite high to me, but honestly, I lack the experience to properly evaluate this.

Looking forward to hearing about your experiences!

And does that include installation and warranty?

That’s quite a firm price. But that’s how it is in the construction industry. The contractors not only have to cover materials and wages but also the office, storage, vehicles, pensions, warranties, and so on.
However, you also have two residential units, which are a bit more complex to service.

Warranty is certainly included, installation is listed under separate installation hours.

I don’t have any quotes, but for a similar scope, I estimate roughly 94,000 euros gross.
