A seemingly simple operation at first glance, buying a piece of land to build your green prefab home, modular house, or energy-efficient tiny home on, can later generate a series of problems that may ruin your plans if you're not careful about a few key aspects. Below, you will find all the details to keep in mind when deciding to take this step and which will greatly help you save on the project.

In general, you need to consider two major groups of factors when planning to build eco-houses, passive houses, or off-the-grid ready homes: legal and location-related.

Legal Factors for Modular Building

• Check the documents An informative urban planning certificate and a valid land registry extract will provide information about the legal, economic, and technical aspects of the constructions in the area, as well as any potential issues with the land in question. This is especially important when considering building green prefab homes, eco modular houses, or Passivhaus constructions.

• Urban or Rural Land Make sure the land is classified as urban. You cannot build modular homes or minimalistic small houses on rural land. Converting rural land to urban land is sometimes impossible or costly.

• Cadastral Survey Cadastral survey issues can lead to delays that may affect your plans for building a prefab house, a tiny home, or an energy-efficient off-the-grid ready home.

• Pay attention to the actual location Ensure the land is positioned according to the description in the documents, as this is crucial for building your eco-houses or modular homes.

Location Factors for Green Building

1. Southern exposure. The ideal land for building an energy-efficient prefab home, passive house, or tiny home should have a fairly large opening to the South – the side of the land should be at least 15-20 m. This is essential for maximizing natural light in your eco modular house or Passivhaus construction.

2. Minimal slope. To avoid subsequent foundation problems when building modular homes or tiny homes, the land should have as little slope as possible.

3. Easy access. The access of machinery or trucks carrying materials for your green building project, such as a prefab house or a modular building, is essential.

4. Direct connection to the street. It is preferable for the land to have direct access to the street for easier connection to utilities when building eco-houses or passive houses.

5. Size and positioning. Be careful that the land is not shaded by hills or large buildings, as this could affect the energy efficiency of your prefab homes, tiny homes, or off-the-grid ready homes.

6. Necessary utilities: water, sewage, and electricity. Sewage can be solved by installing a micro-treatment plant for your eco modular house or Passivhaus construction. There's no need for gas.
