Here we can emphasize that the level of maintenance is remarkably affected by the life expectancy of house components; The other items that impact the lifespan of house components are:

According to the construction procedure and practices that indicate the most Important item is that the house floor must be designed at reasonable height above the ground level along with appropriate waterproofing and drainage to avoid any flooding happens for the house; So, in terms of basement floor (underground) materials shall be in high quality, less maintenance and with low environmental Out turns.

Style, Intensity of use, Grade of maintenance, Quality of products, Climate conditions and Installation classification.

• Heating/Cooling units, Elevator, Electrical outlets, Basement and Driveway heated floors and Backup Generator:

Equipment design and strength, Level of operation and utilization and Maintenance plan.

As a conclusion, we can say that generally there are various life expectancy factors are involved and each component has different lifespan depends on

the influencing items; Also, two important elements of building’s longevity are:

1. A) Adaptability: Means that it should be easy to change the room layout for future requirements and needs.
2. B) Durability: Which means appearance, simply at the end of the day, you should build/develop something that will like

• All of numbers are based on Fortune Luxury Homes team experience and to achieve mentioned life expectancy, the building shall be well-maintained.
