According to the national standard "Code for Planning and Design of Urban Residential Areas" GB 50 180-93, the residential sunshine standard in Article 5.0.2. 1 in 2002 (and mandatory provisions) shall comply with the provisions in Table 5.0.2- 1; For specific cases, the following provisions shall also be met:
(1) The winter solstice of residential buildings for the elderly should not be less than the standard of 2 hours of sunshine;
(2) Adding any facilities outside the original design building shall not reduce the original sunshine standard of adjacent houses;
(3) The sunshine standard of new residential buildings in the old district reconstruction project can be reduced as appropriate, but it should not be lower than the sunshine standard of 1 hour in severe cold days.
(Comment: The back building has violated the second paragraph, and the third paragraph has not violated it, but this is not the transformation of the old district and should not be lowered as appropriate, so there is no problem of 1 hour. )
The horizontal spacing of residential buildings in 5.0.2.3 shall meet the following requirements:
(1) strip residence, multi-storey should not be less than 6m; Should not be less than13m; Between high-rise buildings and residential buildings on various floors;
(2) Visual hygiene factors should be considered between high-rise tower houses, multi-storey and middle-high-rise point houses and various multi-storey houses with windows on the side, and the spacing should be appropriately increased.
(Comment: This is about visual hygiene. According to 1, both the former and the latter should belong to strip houses with a lateral spacing of 6m, mainly considering fire prevention. On the other hand, there is no room when the land is sold for 6 meters in rural areas, so the former should be realistic. The former requires 2 meters, which is relatively moderate, but this answer suggests that 3-4 meters is more reasonable. If the house is too close, it will be bad for both families. The boundary can be connected, but the house can't be close. Even if Liancheng has built a building, the Planning Bureau still has the problem of withdrawing the red line. Once withdrawn, it will be 8, 15, 20. It is the result of the interaction of many factors. )
Article 5.0.3 Residential layout shall meet the following requirements:
5.0.3. 1 Choose lots with superior environmental conditions to decorate houses, and the layout should be reasonable and compact;
The entrances and exits of residential buildings in Mianjie, 5.0.3.2 should avoid opening directly to urban roads and residential roads;
5.0.3.3 should be mainly used for sunshine, cold protection, heat preservation and sandstorm prevention in winter in building climate zones I, II, VI and VII. In the climate zones of Class III and IV buildings, the requirements of summer heat protection and natural ventilation should be considered.
In the hilly and mountainous areas of 5.0.3.4, besides considering the relationship between residential layout and dominant wind direction, we should also pay attention to the influence of local wind caused by topographic changes on cold prevention, heat preservation or natural ventilation of residential buildings;
(Comment: According to Article 2, the gate of the latter can't directly face the road, and Articles 3 and 4 don't allow the latter's house to be built like this. )
National standard "Building Lighting Design Standard" GB/T 50033-200 1, 4. Daylighting quality, 4.0.4 Daylighting design, attention should be paid to the directionality of light, and shielding and unfavorable shadows should be avoided. For example, in writing, natural light should enter from the left.
Local planning bureaus have regulations on sunshine. Now, compared with the most unfavorable city in north latitude, "Regulations on the Management of Residential Building Spacing and Residential Sunshine in Shenyang", Article 15 of Order No.64 of Shenyang Municipal People's Government, if the short sides of two buildings are opposite and at least one building is residential, the building spacing shall be implemented according to the following standards: (1) The building spacing between the short sides of multi-storey buildings shall not be less than 8 meters; Thirtieth because of new buildings affect the surrounding residents sunshine and cause people to petition, the construction unit should actively cooperate to solve the reasonable demands of petitioners. Those who unreasonably obstruct the office and production order, insult and beat staff members shall be punished by the public security organs in accordance with the provisions of the Law of People's Republic of China (PRC) on Public Security Administration Punishment; If the circumstances are serious enough to constitute a crime, criminal responsibility shall be investigated by judicial organs according to law.
For example, if the case is solved, the former should not sue the latter, but should sue the local planning department in the form of administrative litigation. The latter is a third-party defendant, and the local planning department will classify the latter as illegal building rectification. No matter which lawyer, judge or magistrate, whether teaching or reasoning, the above provisions are important, even decisive basis. Even if we don't talk about national standards and laws, only talk about truth, the latter two schemes are not good. Who has such a big place to build a wing instead of a main room? The gate faces the east road, which is not standardized and is not good according to folk customs. As for how bad it is, it is not convenient to say more. We just try to change our position and stand in the latter position. We should go in the same direction as the former, with the gate facing south. If you consider that there is a road in the east that can be used to do some business or something, then open a secondary entrance and a side door or a secondary window.
Besides shelter, sunshine, visual hygiene, fire prevention and other problems, there are also problems of building houses in rural areas that cannot be higher or lower than others, or even a brick. But with the current economic development, everyone is building tall buildings, and the ones behind them must be high, so there is no big problem. In the long run, it is only a temporary phenomenon that everyone will be flush in the future.
I hope the former can communicate peacefully with the latter, and I also welcome the latter to read this answer.
Public welfare answer.
