One Day

‘One Day Project’ is the inHAUS response to the urban, intense, and sometimes accelerated pace of life, which force us to be highly decisive to respond to everything: family, work, friends, free time, …

From inHAUS architecture we look for a logical and functional response to this lifestyle. The maximum work in quality and versatility in the spaces to adapt to the needs of life with special attention to the minimalist design; and all these as soon as possible.


We know that time is money, so that the philosophy “one day project” comes up. We invite you to a working day with a complete, exclusive and intense programme for the most interesting housing projects. In just 24 hours you may see your customized housing project.

Once a month we organize “one day project” providing the selected project with a team of four architects (managing arquitect, project manager, ideational architect, developmental architect) a building engineer and an interior designer. All of them are experts in design and architecture, highly qualified to find the best solution for your house in just one day.

We choose carefully the plot on which we are going to work. To be able to work with a wide range of options it is very important to know the land conditions. It is essential that the plot is buildable. In addition, the wider and flatter the land is, the more versatile we can give the house.
