In recent years, homes built with natural materials have drawn attention as awareness of health and environmental issues has grown.While homes made with natural materials offer excellent comfort and health benefits, it is important to understand the costs and precautions as well. This article clearly explains how they differ from conventional homes.
What is a home built mainly with natural materials, and what benefits does it offer?
A home built mainly with natural materials is one that primarily uses naturally derived building materials such as wood, diatomaceous earth, plaster, and solid wood, rather than chemically refined materials. Its main benefits are as follows.
- High heat retention and humidity-regulating performance help reduce utility costs
- It helps suppress the growth of pests such as mites and maintain clean air
- It feels pleasant to the touch and offers a strong relaxing effect
What benefits come from natural materials that do not rely on chemicals?
Many building materials used in conventional homes contain artificially refined chemicals, such as adhesives, preservatives, and paints. Because homes made with natural materials minimize these substances, they can reduce the risk of sick house syndrome and chemical sensitivity.
However, some people may have allergic reactions to natural materials themselves. If you are prone to allergies, consult the builder in advance.
How much more does it cost compared with a conventional home?
The construction cost of a natural-material home is typically about 4 million to 7 million yen higher than that of a conventional home. The main reasons are the specialized construction methods and the higher cost of the materials themselves.
If your budget is limited, a hybrid approach that introduces natural materials only in selected areas can be effective.
- Use natural materials only in the living room
- Use natural materials only in the room of a family member with severe allergies
What should you watch out for when choosing a natural-material home?
Natural materials may be less resistant to scratches and stains than standard building materials. The main points to note are as follows.
- Solid wood: it may crack or warp during the drying process
- Diatomaceous earth and plaster: cracks may occur due to changes in humidity
By understanding these issues in advance and choosing finishes that make them less noticeable during construction, you can maintain a beautiful appearance over the long term. Before building a home with natural materials, careful advance coordination with the builder is important.

FAQ: Common questions about natural-material homes
Q1. Does a natural-material home completely eliminate the risk of sick house syndrome?
The risk is significantly reduced, but it varies depending on the types of materials used and the construction method. It is important to choose materials with low VOC (volatile organic compound) content.
Q2. Is it difficult to maintain a natural-material home?
Solid wood floors require regular waxing, and plaster or diatomaceous earth walls need partial repairs where they become dirty. They require more effort than conventional homes, but the ease of repair and long service life are clear advantages.
Q3. Can an existing home be renovated with natural materials?
Yes. You can introduce natural materials partially, starting with replacing flooring or repainting walls. Costs can be kept much lower than with a full renovation.
Q4. Are fire resistance and earthquake resistance a concern with natural-material homes?
With proper design and construction, they can achieve fire and earthquake resistance equal to or better than that of conventional homes. Review the builder's track record and design details carefully.
Q5. Are natural-material homes suitable for households with children or pets?
Because they carry a lower risk from chemicals, they are particularly suitable for children and people who are sensitive to health issues. Susceptibility to scratches can be addressed through material selection and finishing methods.
