Hello!
My partner and I are currently considering purchasing a sloped plot of land to build a bungalow with a fully usable basement. By fully usable, I mean the basement would be completely open on two sides (floor-to-ceiling windows). On the other two sides, it would be a typical basement. The soil is heavily clayey.
I am interested in getting a rough idea, without naming any figures upfront, of what an L-shaped bungalow with a fully basement constructed using waterproof concrete and drainage might cost, with approximately 145m² (1560 sq ft) on the ground floor and 170m² (1830 sq ft) in the basement (part of which would be used as a terrace). For clarity, the basement should have three sides poured in waterproof concrete, while one side and many of the interior basement walls should be built with masonry for climate control reasons. The ground floor should be entirely masonry, and a hipped roof will be built on top.
The plot of land is about 1000m² (12,000 sq ft) and will be purchased with a budget of 200,000 euros plus additional costs, fully covered by equity. What kind of ballpark figures can I expect for the house construction?
Thank you.

Based on a "standard" basement but constructed as a waterproof basement (pressure-tight basement), you should expect to invest around EUR 276,000 for a bungalow built to KfW 70 energy standards. Additional finishing costs apply for converting the exposed parts of the basement into living space; I cannot provide reliable figures for this, as you did not specify what you mean by a living basement.
What is the purpose of this mixed-material approach?
To the above approximate price, you must add the costs of soil replacement—which can easily add up to around EUR 15,000—as well as the mandatory additional construction costs in the range of EUR 30,000.
Kind regards

Hello,
Based on a "standard" basement, but executed as a waterproof basement (pressure-tight basement), you would need to invest approximately EUR 276,000 for a KfW 70 bungalow. Additional finishing costs for converting parts of the exposed basement into living spaces must be added; I cannot provide reliable estimates here, as you have not specified what you mean by a living basement.
What is the purpose of the material mix?
To the approximate cost mentioned above, you also need to add the expenses for soil replacement – this can quickly add another EUR 15,000 – as well as the mandatory incidental construction costs, which are around EUR 30,000.
Kind regards Hello!
Thank you for the reply; I honestly did not expect a useful answer to my general question.
The material mix is simply because the living comfort in a fully pressure-tight basement cannot be as pleasant as in a masonry one, meaning breathability. The basement will be arranged on the open side in the following order: wellness room, children’s room, bathroom, children’s room. All these rooms would have floor-to-ceiling windows or doors leading to the garden and could therefore be constructed with masonry without issue. The opposite basement rooms, i.e., those below ground, should be standard rooms such as laundry, utility room, and workshop/storage.
All in all, would I be able to manage with around EUR 300,000 plus a reserve of EUR 30,000?
