However, there are more things to be concerned about regarding garage roof extension

1. Garage area: Should be designed to suit the number of cars, the proper size is at least 2.5x5.5 m2. for parking 1 car and 5.5x5.5 m2. for parking 2 cars.
2. Garage structure: For safety reasons, it is recommended if there is enough space to expand, the garage structure should be separated from the house structure. But in the case of limited space, should consult with an engineer or an experienced expert before making a decision whether to use wires to fix the house wall or support some garage structure with the house structure.
3. Garage floor: Properly prepare the garage floor to slow down the collapse because each car has a different weight if the big car weighs around 2,000 kgs.
