December 29, 2020, on strengthening the Binhai New Area civil building planning and design innovation of the guiding opinions, in the Tianjin Municipal Planning and Natural Resources Bureau website for comments.

Solicitation of opinions put forward

Encouragement of architectural design innovation, located in the riverfront, coastal and other important urban open space (such as large-scale water surface, ecological landscape axis, urban parks, large-scale civic plaza, etc.) of the civil building, through the installation of staggered floors, retreat platforms and other ways to set up the balcony, to improve the lighting and ventilation conditions, optimize the outdoor activity space, enrich the urban building level and shape, and enhance the environmental experience.

Look at the details of the draft

Advocating a public **** transportation-oriented urban spatial development pattern, clustering urban functions around rail transit stations, moderately increasing the intensity of land development around the stations, and developing the ground and underground as a whole, to create a compact, intensive, and efficient urban development pattern.

(a) allows the land within 1 kilometer around the Binhai new area rail station mixed development and utilization of urban renewal projects, construction indexes according to the actual demand reasonably determined. In the control detailed planning and urban design preparation, residential project land area ratio, building density, building height can be moderately in accordance with the "urban residential planning and design standards" relevant requirements for optimization and amendment (see table). After the city fire, construction and other aspects of the demonstration agreed, in accordance with the procedures reported to the district government for approval and implementation.

(2) Encourage the Binhai New Area construction projects in accordance with the "Tianjin Interim Provisions on the Management of Planning Land Compatibility" relevant requirements for the implementation of the policy of planning land compatibility, under the premise of rational layout, the proportion of planning land compatibility can be moderately increased to 30% (except for industrial land, logistics and warehousing land).

Encouragement of architectural design innovation, located in the riverfront, coastal and other important urban open space (such as large-scale water, ecological landscape axes, urban parks, large-scale civic plazas, etc.) of civil buildings, through the set up of a staggered floor, the return of platforms and other ways to set up terraces, to improve the lighting and ventilation conditions, to optimize the space for outdoor activities, enrich the urban building levels and shapes, and to enhance the environmental experience.

The design of buildings with balconies should be in line with regional urban design requirements, and in areas where urban design is not prepared, the development unit should organize the preparation of an overall planning program for review, coordinate the design of the surrounding adjacent plots of land, and safeguard the architectural space and form of the staggered and coordinated.

The balcony should be set up in conjunction with the public **** part of the building, and should not be set up for a single residential unit.

Encourage the creation of rich and beautiful fifth elevation of buildings, and form flexible and diverse architectural forms through design methods such as sloping roofs and balconies.

When a building adopts the form of sloping roof, 60% of the horizontal projected floor area of the sloping roof is not counted in the floor area ratio if a building space is formed, but it is required to pay the land premium; if a building space is not formed, the floor area is not counted.

Development projects located within the range of 200 meters from the urban side line of the planned green areas along the Haihe River, construction projects within the zoned urban renewal areas, and development projects on top of the metro are permitted and encouraged to create places conducive to stimulating exchanges and interactions, places with vitality and the spirit of innovation, and places with the spirit of participativeness and openness*** enjoyment, through the installation of elevated platforms, and to shape the river-friendly and waterfront urban space, and promote urban renewal and comprehensive development of metro stations.

The installation of elevated platforms in development projects shall comply with the following management regulations.

(i) Calculation of floor area ratio. Allowed and encouraged overhead area of 200 square meters or more or accounted for more than 1/3 of the horizontal area of the main structure of the building in which the overhead portion of the columns, shear walls to the ground and the net height of more than 3 meters above the area of less than 5 meters, as well as used for urban transportation overhead portion of the calculation of the floor area ratio is not (construction projects such as elevator shafts, foyers, aisles and other enclosing parts of the construction project and the use of overhead space to set up should be built ancillary facilities, as well as other laws, regulations, and documents) (except for those with special requirements). Overhead space shall not be closed without authorization and shall not change the nature of use.

(2) Calculation of building density and green area ratio.

1. The part of the ground floor of the building that is elevated for parking garage, transportation space and public **** space is not counted as building density, and the building density on the elevated platform is taken as the building density of the project. Various kinds of supporting facilities and commercial facilities set up in the elevated floor are counted as building density.

2. Under the premise of meeting the requirements of building load safety and heat preservation, the planning encourages the greening of the top of the platform, and the greening of the platform can be converted into a certain green area rate (see the following table) and included in the green area rate control index of the plot.

(3) Within the red line of the project site (including the overhead floors), within 5~15m of the inward retreat of the building boundaries along the street, it can be used as a civic plaza, children's playgrounds, pocket parks, mutual aid gardens, etc., for people's activities, exchanges and resting places, and the area of the area is counted from the beginning of the interface of the buildings located along the street; the space should not be used as a parking lot. Encourage the overhead floors to set up multi-functional buildings in accordance with the Tianjin Planning Land Compatibility Policy to increase the vitality of the streets.

(4) parking lots can be set up under the overhead floors, and the overall projected area of the outer contour of the area should not be greater than 1.2 times the sum of the areas of all categories in "(3)".

(E) the parking lot under the overhead shall open a part of the parking space, the ratio of not less than 10% of the number of non-underground allocated parking spaces, as a social parking lot for public use.

(vi) The elevation height, face width and depth of the building below the elevated platform shall be balanced and orderly, and coordinated with the neighboring buildings, city streets and natural environment; appurtenances and elevated floors are encouraged to be harmonized with the main body and the surrounding environment, and building equipment and parking lots shall be skillfully shaded and hidden through design means.

Civil buildings are encouraged to adopt natural lighting and ventilation to improve building quality. Civilian underground space is appropriate to use sunken courtyards, patios and other ways to increase natural lighting and natural ventilation, underground building space and structure shall not exceed the red line of the project site. Construction units can make full use of underground space to set up public **** facilities (homes for the elderly, child care parks, schools, and other special requirements, except), involving operational land premiums should be paid.

Based on the principle of benefiting the people, residential buildings in Binhai New Area are encouraged to set up balconies to enhance the quality of living. Requirements are as follows:

(a) each set of residential buildings protruding from the main body of the structure of the balcony, windows, outdoor air-conditioning units, such as partition and other components of the horizontal area of the sum should not exceed 15% of the total floor area of the set and should not be greater than 25 square meters. One of the residential building balcony maximum depth should not be greater than 2.10 meters.

(b) the set building area is not greater than 100 square meters, the sum of the projected area of the structural base plate of each balcony should not be greater than 8 square meters; the set building area is greater than 100 square meters and is not greater than 130 square meters, the sum of the projected area of the structural base plate of each balcony should not be greater than 15 square meters; the set building area is greater than 130 square meters, the sum of the projected area of the structural base plate of each balcony shall not be greater than 20 square meters.

(3) the balcony of the residence regardless of whether it is closed or not, in the main structure of the balcony, should be calculated according to the horizontal area of its structural periphery full area; in the main structure of the outside of the balcony, should be calculated according to the horizontal projection area of its structural base plate 1/2 area. The relevant measurement standards are in accordance with the relevant regulations of the Binhai New Area.

Encouragement to improve the quality of architectural design of the residential category through the addition of residential suite **** enjoyment space.

The standard floor height of residential buildings is generally not more than 3.6 meters, and the floor height of the foyer, living room, dining room and other through-height parts of the building should not be more than 7.2 meters, and the sum of the through-height parts of the floor area should not exceed 30% of the total floor area of the household set.

Through-height parts should be designed in accordance with the actual use, and should not be reserved for the later addition of floor slabs, mezzanine floors, and structures and structures of enclosed spaces, so as not to cause safety and fire hazards.

Strengthening the supervision and management work at a later stage.

(a) The construction unit should be based on the principle of improving the level of architectural design and enhancing the quality of the building, and organize the design unit to do a good job in the preparation of the program. Shall not create conditions for increasing building area and changing the nature of use through latent design. Construction and design units should make corresponding commitments to this article when applying for construction project planning permits. For violation of the commitment of the construction and design units, in accordance with the breach of trust behavior.

(2), the use of this opinion for the development and construction of the project, the construction unit should be in the development of the project's main entrance to set up bulletin boards used to hang stamped with the business seal of the planning and approval department of the general layout of the planning and architectural drawings, as a long-term display, shall not be canceled without authorization.
