Chengdu, the "fourth generation residence", can realize its idyllic dream when landing at home.

Imagine that in a high-rise residential building, each floor is a small block, just like a quadrangle, 60 stories high, spacious like a villa, where neighbors blend in and children play ... This kind of housing is not a science fiction scene, but a "fourth-generation housing" that has already started construction.

On July 27th, the "Fourth Generation Residential Southwest Summit Forum" was held in Chengdu. Domestic architects from Tsinghua University, China Academy of Engineering Physics and other universities, as well as the heads of 89 domestic real estate enterprises, gathered together to discuss this architectural innovation concept.

Imagine planting flowers and walking the dog without going downstairs.

At the forum site, sand painting scenes frequently change: the first generation of thatched houses, the second generation of brick houses, the third generation of elevator houses, and the fourth generation of urban forest garden houses ... People are like sitting on a time machine, moving from the past to the future.

In the view of Zheng Daqing, the inventor of the fourth-generation residential patent, the difference between the third-generation residential and the fourth-generation residential mainly lies in the difference of green space: "The third-generation residential greening is very good, but the interior of the residential is closed, so it is naturally not the most ideal residential only by going out to contact; The fourth generation house is a quadrangle, similar to the superposition of villas. Each floor is designed with 4- 10 households. In addition to the public courtyard, every household has its own private courtyard, which can grow flowers and grass, walk cats and dogs, and realize everyone's pastoral dream. "

The floor-to-ceiling balcony is equivalent to a house.

Here, the forum is in full swing; On the other hand, in a construction site named "July 1st Square" in Xindu District of Chengdu, the "fourth generation residence" is changing from blueprint to practice.

Song Yang, director of the Chief Engineer's Office of Xindu District Planning Bureau, said that the biggest difference between this scheme and other houses is its balcony design, ranging from 40 square meters to 100 square meters. "The largest diameter is seven or eight meters, which is equivalent to the area of a house."

Faced with this unprecedented architectural form, Xindu District Planning Bureau asked Chengdu Planning Bureau for instructions, consulted professional design institutes, and compared with the relevant policies and professional regulations currently implemented, found that the project was not illegal, but an innovation in architectural concept, so the project finally passed the planning approval link.

Is the controversy a green stunt?

After the concept of the fourth generation residence was put forward, many architects questioned whether the skyscrapers covered with grass trees were sustainable ecological designs or superficial green gimmicks.

He Wei, the project manager of Chengdu Qiyi Real Estate Co., Ltd., believes that the fourth-generation residence is more about the adjustment of technical methods, and the construction difficulty and materials have not increased much.

At present, all parties are more concerned about how to maintain the balcony garden that already belongs to the owner's private property. At the forum, the follow-up management mode of the fourth generation residence has been involved: each household in courtyard greening will be selected and adjusted according to the local climate conditions, and professional greening companies will be invited to operate.

On July 24th, Chengdu issued "Measures for the Management of Green Space in Residential Quarters in Chengdu (Trial)" to standardize the management of green space in residential quarters, but the three-dimensional greening and the management of private hanging gardens have not been involved.
