Hello everyone,
I registered here hoping to get some clarity on our building planning situation.
We are considering purchasing a plot of land to build a prefabricated house without a basement. The plot (400 sqm (4,300 sq ft)) will be separated from the rear part of an existing property and accessed via a right of way.
We are trying to clarify in advance, in terms of feasibility and potential purchase price, what additional costs we might face. The biggest part will likely be the utility connections. The distance from the street where the “parent property” is located to the house will be about 26 m (85 ft).
So far, according to the local technical service providers and city drainage authority, we have been told that there is a separate sewer system and that rainwater must be locally infiltrated. Additionally, a lift station (pump system) is necessary.
Apparently, we have to handle the entire installation ourselves.
The following cost estimates were given to us as a basis for judgment:
Wastewater:
Connection to the public sewer network at the property boundary: €1,500–2,000/m (per meter)
Connection on private property: €1,000–1,500/m (per meter)
House connection pipes: €500/m (per meter)
Lift station (pump system): €3,000–6,000
Rainwater:
Infiltration system: €3,000–5,000
House connection pipes: €500/m (per meter)
If I roughly calculate, just sewage costs alone come to around €35,000. Freshwater, electricity, and telecom are not included yet (I’d appreciate your guesses here as well).
If I have to estimate all connections up to the house at €50,000, this does not seem proportional to the land value.
Are these assumptions realistically applicable?
Please forgive my possible naivety, but I am completely new to this and we are only at the initial planning stage.
Unfortunately, online information shows very different figures.
Thank you very much and have a nice weekend,
Tim

First of all, thank you for your response.
Of course, we wouldn’t want to underestimate the costs, but with a land value based on the standard land price of around €70,000, having €50,000 just for utilities connection feels disproportionate and makes the whole project seem unattractive…

This is especially true if the height levels are poorly done.
Side connections are very expensive. €1000 per meter (about $1100 per yard) for underground construction adds up quickly, plus manholes, connection to the street, and so on. 50,000 euros (about $55,000) might be a bit high, but you won’t manage it for less than 30,000 euros (about $33,000).
Just paving the driveway will cost another 20,000 euros (about $22,000).
By the way, 400 square meters (about 4,300 square feet) for a detached house is almost impossible. Do you already have a floor plan ready?

I would plan the wastewater inspection chambers close to the property boundary, so earthworks can be coordinated with other utility providers.
Your trusted excavation contractor will offer a fixed price for the trench length plus around the house (for downspouts)… Often, house connection costs include up to 15 meters and are billed as a flat fee by the utility companies.
If you have a prime property, I would avoid paving anyway. Gravel is sufficient.

400 sqm (4300 sq ft) for a detached house is basically impossible. You can build a nice house on, for example, 20 x 20 m (65 x 65 ft) or 15 x 26 m (50 x 85 ft). The problem is often the turning radius needed for vehicle access.
