ᐅ Realistic Cost Estimate: Single-Family Home with Challenging Site Access

Hello everyone,

I have been following this forum for a while and first of all, a big thank you to everyone who shares their advice here and sometimes also speaks hard truths. I didn’t originally want to create a new thread but intended to form an opinion based on other discussions. However, you convinced me that this building project is too individual for that. So here is our plan:

- Building a new single-family house in the far north of Germany (Schleswig-Flensburg region).
- Plot size is over 1000sqm (10,764 sq ft).
- Total square meters are not so important as long as the layout works.
- Basement is not planned.

What we would like:
- Open-plan kitchen-living area of at least 36m² (388 sq ft).
- Guest room (at least 10m² / 108 sq ft) and small guest bathroom with shower on the ground floor, so that in old age, with disability, or a broken leg, the ground floor can be used independently and possibly serve as a bedroom.
- Utility room / storage room / pantry with heat pump of at least 8m² (86 sq ft) (KfW 40 standard would be great, of course).
- Upper floor with three rooms (1 office, 1 master bedroom, 1 child’s room) each at least 14m² (151 sq ft) and one bathroom. Our dream would be a “walk-in” (what a silly word – aren’t all showers walk-in?) shower to avoid having to clean those limescale-rusty, annoying shower enclosures.
- We could contribute labor for garden landscaping and painting/wallpapering; otherwise, we would prefer a turnkey build.

As for the house style, regionally typical Frisian houses or captain’s houses (with all the “cute” features like small gables, etc.) are in consideration, or also not completely unimaginative “normal” single-family houses. We are not afraid of Bauhaus-style concrete marvels either, but those tend to be more expensive. In terms of fittings, no “gold-plated faucets” and no smart home – but decent and presentable.

The big BUT: the plot is not connected to utilities, and the distance to the street is about 65m (213 ft), of which 50m (164 ft) is a paved driveway and paved parking area that would have to be dug up (across another property). The connection costs and incidental construction costs worry us quite a bit. Does anyone have experience with such a “mammoth connection” for a relatively small building project? What realistic costs should we expect for both?

We would greatly appreciate any thoughts on this project, thank you very much in advance!

Our good fairy wouldn’t be able to do much with the existing apartment; it really differs in every way from the plan.

So what? - That is practically almost always the case. Trying to find similarities here would be the most frustrating goal, and therefore it should never be the purpose of the project. It is more about the educational, slowly dawning ‘Eureka’ moment.

I looked up what the drinking water connection cost us back then. We paid 15,000 for 65 meters (213 feet) of piping. However, that was in 2014 before inflation. Today, the cost is roughly double that. This does not include any roadwork, electricity, sewage, or telephone. So, the costs are really going to be interesting.

I received my final bill today. In total, I paid around 15,000 EUR for drinking water, electricity, gas (yes, gas 😉) and telecommunications. That’s for 12 meters (39 feet). At the 2021 quoted price. Oh, and 3,500 EUR to the utility company for the wastewater sewer and driveway with a lowered curb. Plus another 1,500 EUR for the connection on my property carried out by the civil engineer...
20,000 EUR for 12 meters (39 feet)...

Then let's do a reset and review our warnings about the costs. Additional construction costs are completely missing. For €400,000 you only get about 135 sqm (1450 sq ft) for the house, basic construction. If you deduct €30,000 in additional construction costs from the available budget, you’re left with just €370,000 for the house, which equals 125 sqm (1345 sq ft). 🙁

The €400,000 is based on around 160 sqm (1720 sq ft) and not so basic at all. The windows and doors installed are higher quality than what large general contractors usually offer, glazed Creaton roof tiles, lime plaster instead of gypsum plaster, brick cladding... I think it’s manageable 🙂

@K a t j a
The neighbors are close family and want to build at the same time to take advantage of synergy effects. We have budgeted €80,000 for site development, and the assumed €40,000 is already our share.

@WilderSueden
We have already talked to the draftsman, otherwise that would be a bit too naive... And you’re absolutely right about the small items. On the other hand, we are also okay with (and familiar with from home) the idea that the interior furnishings and garden will grow over the years and that not everything has to be bought new and expensive right away. We will bring our own furniture and don’t need anything big new for now. But I understand what you mean, there will be various small expenses here and there, smoke detectors, outdoor lights, mailbox, who knows what… and then there is the unknown number of things we don’t even know yet that we will need.

@11ant
Oh right, well, hopefully our initial needs analysis was already there for that.

@xMisterDx
That’s enough to make your head spin 😱

What more can be said. You won't get far with 400,000 EUR, but just go ahead—it's been said often enough by now.

However, this statement isn’t very meaningful because conditions vary everywhere. Also, you can save a lot of money by doing some of the work yourself.
