Hello everyone,

We have a plot of land (see site plan) and have started planning our dream house without an architect. Before we move forward in more detail, it would be great to receive opinions, ideas, and perspectives.

On the floor plan, you can see an electrical transformer to the east. It is quite tall and does not provide a pleasant view. Therefore, the utility room is planned here, separated from the house with access to the "breakfast terrace."

We are planning with the future in mind. This means we want all the essential living spaces on one level. Upstairs is for the children and grandchildren when they visit, as well as hobby rooms, an office, etc. The area above the living room is open. Downstairs, it is important for us to have separate areas. The kitchen/dining and living rooms should not be an open, connected space. We often have guests while others want to watch a movie in peace.

We welcome any extraordinary ideas. The house should be unique. But we also appreciate advice on realistic feasibility.

The house will be built as a timber frame house.

The building plan allows for few restrictions. The building envelope is shown on the drawing.

Thank you and best regards,
Andreas

Let’s do the math: 260 m² (2800 sq ft) * 2000 EUR/m² = 520,000 EUR —> No, that’s not realistic, especially with such a structurally demanding design and certainly not for a (high-quality) timber frame house.

Let’s do the math: 260 m² (2800 sq ft) * 2000 EUR/m² (186 USD/sq ft) = 520,000 EUR (about 608,000 USD) ⇒ No, not realistic, especially with such a structurally demanding design, and certainly not for a (high-quality) timber frame house.

The tool currently shows 208 m² (2240 sq ft) of living space. That means 208 * 2000 = 416,000 EUR (about 486,000 USD) would be quite reasonable. And yes, I also hope that an architect can still reduce that.

Question: What exactly is included in the rough estimate of 2000 EUR/m² (186 USD/sq ft)? Ancillary building costs? Only the shell construction? Including plumbing, flooring, etc.?

More like 208 × 2,500 €/m² (approximately $232 per sq ft) = €520,000 plus additional construction costs ...

I had only read something about a total of 300 m² (3,229 ft²) of floor area here and therefore assumed 260 m² (2,798 ft²) of living space.

The often quoted 2,000 € per m² (186 sq ft) is, of course, just a rough estimate that is steadily rising. This is especially true for sophisticated architecture, where costs increase independently of general market trends. For that amount, you get a house plus additional construction costs, flooring, and wall finishes.

You have already built before. And with a prefab company. So you should know how the process works. Prefab companies have standard house models that can be modified, but if you want a custom build, you would hire an independent architect and construct your timber house either through individual contracts or with a general contractor you and your architect trust.

And then you know that all costs related to the land come on top. This is mentioned on nearly every other page here.

You cannot take flat rate figures for calculations as fixed. The €2000 figure is from an accounting perspective dated 2019 and applies to standard solid construction.

That was 20 years ago now … and I don’t want to make the same mistakes as back then.
There are definitely prefab companies that offer “free” planning. But they use their own architects.

I understand that the land and the garden costs come on top. But I wasn’t aware of additional construction costs and flooring.

We paid 240K for 160sqm (1722 sq ft) back then. I guess I can’t really rely on those experience values anymore … but I understand that for prefab house construction, there are no standard flat rate values.
