Now many property buyers don't know enough about the pool. Simply put, the smaller the pool area, the smaller the additional cost that buyers need to invest. As for the pool area, the pool area will be affected by the apartment type, the interior area, the number of public facilities and the scale of the building itself.
Public pool refers to the construction area shared by the property owner of the whole building and all public parts of the whole building. Whether it is multi-storey or high-rise, commercial housing has a so-called pool area. But how to calculate this area, many property buyers are at a loss.
1. Elevator shaft: the size is determined according to elevator type selection. The elevator guide rail and counterweight guide rail are installed on the shaft wall, and the elevator door is installed in the reserved door opening.
2. Pipeline well: the space of various pipelines, including vertical pipelines, horizontal pipelines, straight-through pipelines and separation pipelines.
3. Stairs: Structures that contain stairs and building components (such as walls or handrails) around stairs. At the same time, it is a relatively independent building part. Contact the transportation of the whole building.
4. Substation: the place where the voltage and current of electric energy are transformed, concentrated and distributed in the power system of residential areas.
5. Computer room: The computer room is a place where telecommunications equipment, computer network equipment and building wiring equipment are installed in the appropriate position of each building for network management.
6. Public foyer: a large public space after entering the house, which belongs to indoor space. Heating and cooling requirements are usually set according to the functional requirements of the building.
7. Aisle: the horizontal traffic space used in residential suites.
8. Guard room on duty: The guard room is located at one side of the gate of the community, and there are lifting railings at the gate of the guard room.
9.* * * Wall: the main load-bearing structure of the house (including foundation, internal and external load-bearing walls, columns, beams, floors, roofs, etc.). ), outdoor walls, etc.
In addition, these will not be included in the pool: warehouses, garage lanes, heating boiler rooms, basements used as civil air defense projects, houses for self-use by selling units, and management houses will not be included in the pool.
The pool shared by two households and two ladders in the same building is larger than that shared by two households and one ladder, but it is certainly not as convenient as that shared by two households and two ladders. The pool of point building and plate building is different; When the house is big, there will be more booths; If the house is small, there will be fewer booths; Residents who only have stairs and have both stairs and elevators have different pool areas. The more public facilities and corridors, the bigger the pool; The higher the stairs, the bigger the pool. In fact, as long as the swimming pool is suitable, it can improve the living comfort.
7-12% of houses below 7 floors;
Multi-storey buildings generally refer to mixed structure buildings with about 6 floors, and the common area includes the horizontal projection of external walls, stairs, staircases and property management rooms (heat exchange station, water pump room, power distribution room, etc.) 1/2. ) provide services for residents. Generally, it accounts for 13% to 18% of the building area. Indoor height can be divided into indoor clear height (the distance from floor to ceiling) and indoor height (the distance from floor to upper floor). The general height is about 2.8 meters, and the indoor clear height is between 2.65 and 2.7 meters. If the indoor height exceeds 4.7 meters, the indoor area shall be calculated as two floors.
The allocation rate of 7- 1 1 layer is 10- 16%;
7-9 floors are small high-rise buildings. Generally, the small high-rise pool depends on the situation of each building, and there are differences between different small high-rise floors. When there is no underground computer room, no shops on the ground floor and the ground floor is overhead, the allocation coefficient of small high-rise buildings is between10% and15%, and that of small high-rise buildings with elevators is between15% and 20%. According to the regulations, elevators must be equipped for floors above 7, so small and high-rise buildings are all within the scope of elevators, featuring convenience and giving life a new height.
The allocation rate of 12-33 layer is 14-24%:
The pool area of high-rise residential buildings is the largest. According to the different building scale, high-rise buildings are generally between 25 and 33 floors, and the stairs of high-rise houses are the highest. In addition, elevators and elevator forerooms in high-rise buildings occupy space, as well as safe passage stairs, and public facilities such as "pipeline wells", "strong electricity wells" and "weak electricity wells" occupy space. Therefore, the pool area of multi-storey buildings in high-rise buildings is much larger.
Villa sharing rate 1-8%:
The villa is a single-family residence with the highest three floors, including basement and indoor garage. Generally speaking, independent villas have no pool area, and conjoined villas have less pool area. The principle of sharing public areas is that this part only exists in the building and is connected with the building structure, and only provides non-profit services to the residents in the building. Buildings that do not meet this condition shall not be included in the pool area.
According to Article 8 of the Purchase Contract, when the developer delivers the house, the error between the total construction area of the house and the area agreed in the contract is within 3%, and the error is above 3%. The extra area is given away by the developer free of charge. The developer is responsible for compensating the owner for the lack of area, and can choose to return a house at the same time.
Calculation formula of pool area:
Construction area = interior construction area+pool area
Pool area = pool coefficient * interior construction area
Allocation coefficient = total allocation area/(interior construction area * total number of units)
Interior construction area = interior usable area+wall area+balcony area
In addition, buyers should pay attention to: the center line of external wall partition and the total calculation of internal wall; Whether the balcony is closed or not, it is completely unsealed.
