In order to improve the construction quality of commercial and residential projects in Jinhua and beautify the urban landscape, the quality control requirements of commercial and residential projects should be clearly defined when formulating the planning conditions of commercial and residential land and the land transfer scheme in the future, and the control requirements should be implemented layer by layer when the project is approved and verified. Construction quality control of commercial and residential projects includes but is not limited to the following contents:
The first is to optimize the overall layout planning.
The land for commercial service facilities in mixed land should be clearly divided into small categories, and the requirements for the proportion of construction area should be clearly defined. Commercial and residential land (excluding commercial complex land) and residential land with a building height of more than 24 meters should be controlled within 23%. The construction area of commercial underground space is included in the floor area ratio. For development plots with no specific urban design guidelines and mainly high-rise buildings, the planning conditions should clearly follow the layout requirements of "low outer ring and high inner ring", strengthen the change of skyline and reduce the oppression on public space; The red line of land use should define the control range of building height zoning in the plot, the height of residential buildings should define the control range of building height zoning in the plot, the upper and lower limits of residential building height should be defined, and the "gradient" connection between height zoning should be done well.
Second, improve the building facade materials.
For large-scale projects along the river, along the lake, along the mountain and along the garden (see Annex for the specific scope of the project), the planning conditions should be clear. The first row of building facades adjacent to the land boundary (taking the building as the measurement unit) should adopt all-stone dry hanging, aluminum plate or aluminum plate thermal insulation and decoration integrated board, etc. , so as to improve the grade of building facade materials.
Third, beautify the fifth facade of the city.
For residential buildings below 60 meters (inclusive), the roof should be in the form of full slope roof, and the maximum clear height of full slope roof structure should not exceed 3.4 meters. Except for the elevator shaft, stairwell on the top floor and the part with unit stairs connecting the escape passage.
Fourthly, standardize the design of single building.
The concave-convex dimensions of the external contour of residential buildings and the sum of all sides shall not be greater than 2.1m. Construction projects in key areas such as along the river, along the lake, along the garden, along the mountain and along the skeleton trunk road. Balcony on the facade of the project residence (including balconies marked as pick gallery, hanging garden, home garden, etc.). ) is fully enclosed; Other areas of the project along the road side of the residential facade balcony (building as a unit) should be closed. The construction area of residential Xing Tao is not less than 75 square meters (except for affordable housing such as resettlement houses). Put an end to illegal space in buildings. No balcony (including equipment platform, corridor, terrace, hanging garden, home garden, etc. ) or buildings shall not be set in the building space; Residential units with four or more floors shall not be designed to be connected with underground space; Shall not set up or reserve beams, walls, columns and other closed high-rise space, high-rise functional rooms; Decorative spaces such as flower ponds and balconies are not allowed; Building space with a height of less than 2.2 meters and patios, lighting wells, ventilation wells, tail gas wells and bay windows that do not conform to the logic of construction and use shall not be set on the ground.
Verb (abbreviation of verb) expands the development of underground space
The construction area of underground space should not be less than 1 times of the construction land area, the number of parking spaces in residential buildings should not be less than 1.3 times of the number of residential buildings, and 10% of the number of parking spaces in public parking spaces should not be included in the parking space index. The height of the first underground floor is not less than 4.2 meters, and the height of the second underground floor is not less than 3.9 meters. Small underground garages shall not be less than 6mx in length and 2.5m in width, and the proportion of mini-motor vehicles shall not exceed 2% of the total number of underground vehicles, and shall not be used as public parking spaces. There are three preconditions for setting up motorcycle parking spaces: they are not set in the underground space corresponding to the main structure line of the house, are not included in the converted parking space allocation index, and are open on three sides, and one of them is hard connected with the main passage.
Sixth, optimize the traffic organization of people and vehicles.
Commercial and residential projects should be designed according to the concept of separation of people and vehicles, and physical isolation should be adopted between motor vehicles, non-motor vehicles and pedestrian passages at entrances and exits. The underground room of the kindergarten should have a separate entrance and exit, and the parking space of the kindergarten should be arranged in the basement, which is physically isolated from the residential area. According to the school regulations of the children in the last 9 classes, 12 classes and 15 classes (including the corresponding nursing classes, class 6 is not required to be set according to the terrain), there should be no less than 50 underground parking spaces, 70 underground parking spaces and 90 underground parking spaces, and obvious signs should be set up to provide convenient underground loop traffic streamline and guidance, and a certain number of ventilation and lighting wells should be set up according to the ground landscape to enhance. Provide convenient underground loop traffic streamline and guidance, and set a certain number of ventilation and lighting wells in combination with the ground landscape to enhance the ventilation and lighting performance of the basement and improve the overall comfort of the underground space.
Seven, supporting facilities should be relatively centralized layout.
Follow the principle of overall layout, convenient use and economical construction, and scientifically and relatively concentrate on the allocation of convenience facilities such as property management houses, pension houses, express delivery houses, sports facilities, 100% public sports facilities, community service stations and community health service stations. Create a "micro service facility center" in the community.
Eight, improve the landscape environment of the community
Centralized green space should be set up in the relative center of the project, with a planned construction of not less than 0.5m2/person and a width of not less than 8m. The area of green space outside the sunshine shadow range of standard buildings should not be less than 1/3, in which venues for the elderly and children should be set up. Community walls and buildings give way to street space, which is superior to greening, and streets enrich the street landscape effect.
Nine, clear self-sustaining scale
Where the transfer of business land involves commercial and commercial purposes, the planning shall clearly support the minimum division of unit area.
(a) the integration of commercial, commercial, entertainment, leisure, residential and other uses of urban complex projects. Among them, business, entertainment, recreation and architecture all require speeches, and no points are allowed. The self-supporting ratio of commercial functional buildings is not less than 50% of commercial buildings (not less than 40% outside the Second Ring Road), and the minimum area of dividing units is not less than 300 square meters (not less than 200 square meters outside the Second Ring Road).
(2) Pure commercial or total commercial building area. For commercial and residential projects with the proportion not exceeding 10% (inclusive), the self-sustaining proportion of commercial and residential projects shall be not less than 50% (not less than 40% outside the Second Ring Road); The minimum business district unit area is not less than 200m2 (not less than100m2 outside the Second Ring Road); The unit area of the minimum commercial division is not less than 300 square meters (not less than 200 square meters outside the Second Ring Road).
There is no requirement for minimum self-sustaining ratio and division unit area for commercial and residential projects whose total commercial or commercial construction area does not exceed 10% of the total construction area.
(3) The project owner should specify the specific location of the speech in the planning and architectural design stage, so as to make the layout reasonable and relatively centralized. Self-sustaining buildings take aquaculture as the unit and apply for immovable property certificates.
Ten, pay attention to the completion plan to verify the details.
Anti-skid and wear-resistant ground parking space in underground space. Tourist parking spaces, paid parking spaces, parking signs in Huaxian County, entrances and exits of marked projects, entrances and exits of underground garages and facilities, etc. Only after the construction is in place can you apply for completion. This notice shall be verified from the date of issuance, and the validity period is tentatively set at three years. At the same time, the previous "eight prohibitions" and "nine regulations" were suspended.
