The benefits of going modular

With energy prices reaching new heights, you have all the more reason to go for a Revonia energy efficient modular house.

Our modular buildings keep the energy costs low and target them towards Net Zero energy standard. Inspired by enhancing historic building traditions, elegance and durability, our unique solution is also designed to last a century and longer – making it even more sustainable.

In addition, our modular houses are a great option if you’re looking to start or expand a commercial business with a bit of uniqueness and lots of attractiveness. Our modular buildings are one of the best values for money to keep business costs low and vacancies even lower.

Quick and comfortable installation

Our houses are made of prefabricated concrete modules that are connected with each other on-site. Thanks to this it is also possible to finish 95% of interior jobs during manufacturing. This allows the house to be installed within only a few days or less. Over 10 years of creating homes has allowed us to improve our techniques to be as optimal and efficient as possible.

Lasts a lifetime with minimal maintenance

Thanks to the fact that the houses are under the soil then that eliminates the need to paint exterior walls, fix holes in the roof or even clean the gutters. The constructional elements are calculated to last ~100 years. In addition to minimal regular maintenance requirements the house will also be protected by many forces of nature like high winds, heavy snow, storms and even in some cases – fire.

Full of uniquely interesting experiences!

Owning a mysterious underground house with vaulted ceilings will probably spark interest in the neighborhood and in a lot of cases even add value to the property it is installed on. In addition to it being an architectural masterpiece it will also be one of a kind, quiet and an overall peaceful experience.

Energy-efficient and nature-friendly

The house will be heavily insulated by the reinforced concrete shell that is covered by PUR foam, on top of what lays ~1m of soil. Thanks to geothermal heating the energy-costs related to heating and cooling will be minimal. The house will become more nature friendly over the time thanks to the minimal repair factor, overall long life and the minimal impact on the surrounding nature.

The ease of installation

A standard house construction takes on average about 10-16 months. This means that before you get your dream house you have to wait at least 10 months filled with a wide variety of contractors that are on-site daily. Even in the case of some modular houses you still have to wait at least 5 months from foundation works to roofing being complete. And this time in some cases also means that the installation can not take place during the wintertime.

Here is where we differ from others. We have 4 stand-ard modules that allow us to design smaller and bigger rooms by combining them with each other. All this while the doorways, windows, inner walls and everything stays customizable. The modules are a one-piece solution, meaning they have a floor, walls, and a roof. Prefab-riction also allows 95% of interior jobs to be finished during production. All of this allows to create different houses with different Revonia’s solutions but with the same quick installation time of only 1-3days ! And yes, we do not rush. We are just prepared!

Who would have thought that owning a home could be this simple?

Do-it-yourself concrete modules

From an idea to plan

Contact us if you would like to order one of our standard solutions or if you would like to design a fully custom solution. After the inquiry, we will specify the estimated manufacturing time, the exact cost with transport and all the other requirements for the project.

From plan to order

If the plan is coming together then it is time to schedule the approximate time for the installation. It is possible to confirm the order up to one year before the day of installation. On average this should be enough time to get permits and finalize any finance plans. We also offer a few financial options to make sure you are getting the home of your dreams. More information can be found from our sales representative. When all this is set and done then it is time to place an order!

From order to production

On average the manufacturing process for a standard solution takes about ~5-8 weeks until it is ready for transport. As long as we manufacture the home – you can already carry out the necessary preparations for its arrival. Quick installation is ensured by a properly sized and leveled hole that is prepared according to our instructions. We will supply all the technical sketches for this. This is the stage where it is reccommended to hire a local contractor.

From production to site

The standard price does not include transport. But can precisely calculate it and offer transport to your new home all around the world, worry-free. We have installed over 1500 projects and have lots of experience with different shipping methods.

From site to installation

On the day of installation, we will arrive at the site and start lifting the modules in place. We will connect the modules with each other and seal the connections. If readiness for electricity is next to the site, then that is also connected. For bigger projects we will also cover the modules with PUR foam on the location. After that the only thing left to do is to cover the modules with soil, and if desired then to also build a retaining facade wall.

Installation ends, enjoyment begins

It’s that simple! Even from the very next day you can start enjoying your new home.

We offer a 5-year warranty for the houses constructional elements that are installed according to our conditions and instructions. For parts fitted to the house we offer a 2-year warranty.
