Selecting the best building stones for your house requires considering several factors, both aesthetic and practical. Here's a guide to help you make an informed decision:

• Purpose: Understand why you need the stone. Are you using it for structural purposes, decoration, or flooring? Some stones are better suited for certain purposes than others. For example, granite and basalt are strong and suitable for structural purposes, while marble and slate might be preferred for flooring and decorative finishes.
  

• Durability: Always choose stones that are durable and can withstand the local environmental conditions. Durability depends on the stone's hardness, resistance to abrasion, and its ability to resist weathering effects.

• Appearance: The color, texture, and pattern of the stone should be in harmony with the overall design of your house.

• Porosity and Water Absorption: Stones used in construction, especially in areas exposed to moisture, should have minimal porosity. A lower porosity means less water absorption, reducing the chances of freeze-thaw damage in colder climates.

• Resistance to Fire: Stone, being a non-combustible material, is generally considered fire-resistant. However, it's always good to ensure that the specific stone you're considering does not disintegrate under intense heat

• Ease of Working: Depending on the application, you might need to cut, carve, or shape the stone. Some stones are easier to work with than others. For example, limestone and sandstone are relatively easy to shape, while granite requires specialized equipment.

• Cost: The cost of stone can vary widely depending on its type, quality, and origin. Set a budget and try to find the best quality stone within that range.

• Availability: Ensure that the stone you choose is readily available in the quantity you need. This will prevent potential delays in your construction project.

• Thermal Conductivity: If you live in a region with extreme temperature fluctuations, consider the stone's thermal properties. Some stones are better insulators and can help maintain a more constant interior temperature.

• Maintenance: Some stones, like white marble, can stain easily and might require regular maintenance. Others, like granite, are more resistant to staining and require less upkeep.

• Environmental Impact: Consider the environmental implications of your choice. Quarrying can be destructive to the environment, so it's a good idea to choose stones that are sourced responsibly. Also, consider the transportation impact; locally sourced stones may have a smaller carbon footprint.

• Test of Time: Look at older buildings in your area made of stone. Which types have stood the test of time? This can give you a clue about which stones might work best in your local environment.

Once you've considered these factors, it might be a good idea to consult with a local architect or builder who has experience with stone construction in your area. They can provide insights into the best choices for your specific needs and the local climate.
