A house with around 80 m² is a full-fledged, compact residential home with room for several bedrooms, a large living kitchen and a comfortable bathroom. This class contains the models whose footprint span includes 80 m². The price per square metre differs depending on the model and fitting level.
This page compares the models of the 80 m² class by starting price and price per square metre and explains the decisive cost factors. In this size class it is above all the individually plannable Signature model that covers the area flexibly.
All prices and areas are starting values from our model data. The actual price depends on materials, technology and interior fit-out and only becomes binding after the final planning.
Key takeaways
- In the 80 m² class the individually plannable Signature model covers the area with a base from 29,000 euros.
- Aurora Frame from 199,000 euros and Lumen from 189,000 euros include 80 m² with their footprint spans.
- The Signature is freely plannable from 15 to over 100 m² and flexibly covers the class from 80 m².
- Construction, degree of customisation and building technology influence the final price more strongly than the sheer area.
- An 80 m² house counts under building law as a full-fledged residential building and requires a permit.

Models of the 80 m² class with price per square metre
The 80 m² class is covered above all by the individually plannable Signature, which is freely planned from 15 to over 100 m² and offers the base from 29,000 euros. In addition, the Aurora Frame and the Lumen include 80 m² with their footprint spans.
The table compares the starting values of the models. The price per square metre relates to the starting price and the starting area and is rounded to 10 euros. For the Signature the value refers to the smallest plannable area and serves only as a base orientation.
Models of the 80 m² class with starting price, price per square metre and fitting level
| Model | Starting area | Starting price | Price per m² | Fitting level |
|---|---|---|---|---|
| Signature | 15 m² | 29,000 € | 1,930 € | individually plannable, 15 to over 100 m² |
| Lumen | 55 m² | 189,000 € | 3,440 € | luxury, natural stone, hipped roof |
| Aurora Frame | 60 m² | 199,000 € | 3,320 € | A-Frame, floor-to-ceiling glass front, loft |
Starting values from the model data. Price per m² = starting price divided by starting area, rounded to 10 euros. For the Signature the base value is only an entry-level orientation, since the area is freely plannable.
What influences the price in this class
In the 80 m² class, construction, degree of customisation and building technology largely determine the final price. The following table ranks the most important factors and their relative effect, without naming concrete euro amounts.
The magnitude describes relatively how strongly a factor typically moves the price. Binding amounts can only be shown in the offer after your final planning.
Price factors for a tiny house with 80 m²
| Factor | Effect on the price | Magnitude |
|---|---|---|
| Degree of customisation | freely planned floor plans raise the investment | high |
| Construction (A-Frame, natural stone, timber-frame) | elaborate constructions increase the price | high |
| Number of rooms and bathrooms | additional rooms raise the costs | medium |
| Building technology (heat pump, glazing) | energy-efficient technology drives the price up | medium |
| Fitting level (kitchen, bathroom, floors) | upmarket materials increase the price | medium |
Full-fledged residential home on 80 square metres
On 80 m², two to three bedrooms, a spacious living room, a proper kitchen and a comfortable bathroom can be accommodated. The Signature is the most flexible model of this class, since floor plan, design and fittings are freely planned according to your draft.
Anyone who prefers a fixed series architecture will find in the Aurora Frame with its A-Frame gable roof or in the Lumen with natural stone and a hipped roof a model whose footprint span reaches into the 80 m² range. Both are set up stationary on a foundation.
Which solution suits your plot and budget is something we clarify in the consultation. For the location question we recommend an early plot check.
