What is the ideal parking space size? This is something you need to know before buying a house or condo. The legal parking space dimensions vary depending on the type of residential property, whether it's a detached house, townhouse, townhome, or condominium.

In addition to designing for sufficient parking spaces, the parking space width must also be appropriate for convenience and safety.

Legal Parking Space Dimensions

The legally mandated parking space size is at least 2.4 x 5.0 meters per car. This is determined for the safety and convenience of car users.

Legal Parking Space Dimensions: Detached House

For a detached house, a parking space that can accommodate all car models should be approximately 2.8 x 5.5 meters for one car. For houses with two cars, the dimensions should be approximately 5 x 5.5 meters.

However, for more comfortable use, a space of approximately 3 x 6 meters for one car and 5.5 x 6 meters for two cars, or more depending on the size of the land, is recommended.

Furthermore, carports or garages in detached houses can be divided into separate garages and garages integrated with the house, which require planning and design before construction begins.

– Garages integrated with the house require careful structural design and calculations. Poor structural calculations can lead to subsidence problems later.
– Garages separate from the house structure experience fewer problems because they are independent. This type is currently popular due to its convenience and reduced future subsidence issues.

Parking Size According to the Law: Townhouses/Townhomes

Townhouses and townhomes on the market come in various widths, ranging from 4-10 meters for the minimum legally required parking space. Different widths result in varying parking capacity.

The Building Control Act B.E. 2522 (amended B.E. 2558) specifies that the minimum parking space must be at least 2.4 x 5 meters. Therefore, the parking capacity for different sizes of townhouses/townhomes is as follows:

– A 4-meter wide townhouse/townhome can park 1 car, with possible additional space on the side for motorcycles. Or plant small potted plants.
– Townhouses/townhomes with a 5-5.7 meter frontage are a popular style, allowing for parking of 1-2 cars depending on the project's design.
– Townhouses/townhomes with a 6-7 meter frontage can accommodate 2 cars. Due to the larger size of the house and the possibility of larger families, each family can have their own car.
– Townhouses/townhomes with an 8-10 meter frontage can accommodate up to 3 cars. Some projects design with 2 parking spaces, allowing for comfortable parking without crowding, and instead focusing on usable space inside the house or adding green areas.

In addition to the width of the parking space being appropriate for the car, the depth of the parking space should also be considered. If the parking space is too small and doesn't leave room for walking, it may be inconvenient to use. Therefore, consider a distance of 30-40 centimeters in front and behind the car.

Parking Space Size According to the Law: Condominiums

Currently, condominiums with 100% parking availability (at least one parking space per unit) are very rare, and most are high-priced condominiums because parking space is related to the construction cost of the building, which in turn affects the price of the unit. The number of parking spaces must be considered in two cases:

__________________________________________

1. Parking space regulations in condominiums calculated based on usable area:

According to Ministerial Regulation No. 7 and the Building Control Act B.E. 2544, condominiums are classified as "multi-family residential buildings" or "apartment buildings." The size of parking spaces based on usable area can be divided into two cases:

– Condominiums in Bangkok: Units with an area of ​​60 square meters or more must have 1 parking space per unit.
– Condominiums outside Bangkok: Units with an area of ​​60 square meters or more must have 1 parking space per 2 units.

2. Parking Regulations in Condominiums Based on Building Size

For buildings with a total construction area exceeding 1,000 square meters and a height of 15 meters or more, or buildings with a total construction area exceeding 2,000 square meters, the parking space requirements are divided into two cases:

– For condominiums within Bangkok, every 120 square meters of construction area must include 1 parking space.
– For condominiums outside Bangkok, every 240 square meters of construction area must include 1 parking space.
After calculating the parking spaces based on the two cases above, construct the unit using the case that yields the largest number of spaces. Comparing the number of parking spaces to the number of units will give the percentage of parking spaces required for the project.
Note: The design and size of the parking spaces... By law, one parking space should be approximately 2.4 x 5.0 meters. There are four main parking space designs:
– Parallel or angled parking not exceeding 30 degrees, with a minimum driveway of 3.50 meters.
– Parking spaces angled 30-60 degrees, with a minimum driveway of 5.50 meters.
– Parking spaces angled 60-90 degrees, with a minimum driveway of 6.00 meters.
– Parking spaces located in front of the building at a 90-degree angle. In this case, architects usually design the parking area to be in relation to the column alignment; for example, an 8-meter distance between columns might allow for 3 cars.

__________________________________________

When buying a house or condo, the legal size of parking spaces, as well as the width of parking spaces specific to each type of residence, is another important factor to consider. The design should provide sufficient parking for the number of occupants and be practical for use. Consider the width and number of parking spaces before making your decision.
