Those who have a legitimate increased need for security usually have money.
Many people are afraid (need for security) and have no money.
What is a dream house anyway....
you can google:
Dream houses and great cultural assets:
Haus Lange and Haus Esthers in Krefeld are dream houses - built by Mies van der Rohe for two textile manufacturers. You can visit them.
Probably the most beautiful concrete can be found in the Tadao Ando building of the Langen Foundation. A hard surface that feels like silk to the touch. Plus a perfect connection between outside and inside. You can also visit it.
Affordable dream of a small château in the countryside:
Currently, in the Franche-Comté region near Besançon, a very neat country estate with 65 ha of land is offered for less than €600,000. A certain regular income to cover the running costs of the small château from the 18th century with over 500 sqm of living space is certainly an advantage.
Dream house for aviation enthusiasts:
The requirements for this house are very specific. John Travolta wanted to be able to park his four-engine jet directly at the house and made it happen. Certainly his dream house.
Dream cob house:
Maybe you have to be English to build something like this. Under Cob House and Grand Designs you can find a fascinating house with an equally fascinating history behind it on YouTube.
