What are the design criteria for residential building units?

Generally taking into account the structural needs and interior layout needs, when our design institute designs residential buildings, the conventional data mainly include:

The minimum size of the bedroom is 2700 and the depth is 3500 (horizontal bed); If it is a double person, the studio is generally 3300, and the minimum depth is 4000, of course, if the conditions are particularly difficult, you can consider doing 2100x3000, you can only put the bed horizontally, and add a dresser. In 80% of cases, 3600x4500 is enough for a couple. As for the lower limit you said, there is an area provision in the specification:

The double bedroom is 10m, the single bedroom is 6m, and the living bedroom is 12m.

In the bathroom, there are regulations on the number of sanitary ware, depending on how many pieces you want to put on, the specification stipulates: toilets, baths (bathtubs or sprays), and washbasins are 3m for three sanitary ware; Two sanitary ware with toilets and baths; 2m for toilets and toilets; In the actual design of a single toilet, the short side should be greater than 900, otherwise it cannot be arranged, and the long side should be greater than 1200, otherwise a urinal can not be placed =.= Other dimensions will need to be combined with the requirements of your design operation.

The main and most difficult space division of the house is to grasp the scale of the room, not only the area is wasted, but also it is the most important space in our life, which is closely related to us and affects our physiology and psychology.

Therefore, the first consideration for the size of the room is the suitability of living, the most basic requirement is to be able to put down some basic furniture and leave a certain amount of activity space, for example, a small room of more than two meters can be used as a children's room, it only needs a single bed and some simple furniture, and children need a sense of restraint, such a small room does not feel depressed, but will feel safe and suitable, but such a room is not suitable for the master bedroom because it can't even put a large double bed, Also as a kitchen, a meter eight of the studio can meet the operational requirements, but this has limited the placement of kitchen equipment, can only be a word type, saying so much means that the design of the house must draw the furniture layout of the room, repeatedly adjust, to achieve the least area out of the best effect, the room scale is not strictly regulated, according to the function of the division, based on the furniture.

I can't provide detailed size regulations, just a general talk, I hope it will help you, although there are no specific regulations on the distribution of rooms, but there are minimum scale regulations, such as the kitchen is already the smallest one meter eight, these residential design specifications are available, you can check it.

You should check GB 50096-1999 "Code for Residential Design".

If you can't get it, tell me that I can send it.

The size of the space is generally a multiple of 3, such as .

The most suitable rooms and depths you said are the experience and skills summarized after doing countless apartment types.

But the main thing is to ensure that the specifications are met.

In addition, the most suitable type of house is different in different regions. There are no shortcuts to this, and everyone's skills are different.

There is no unified standard, mainly depending on your own needs.

What are the bases for the design of residential buildings?

Different family demographics form different household types, and different household types require different residential unit designs. When designing a residential package, it is important to first understand the demographic composition of the household. The composition of household population can be considered from three aspects: household population size, household generation and population structure.

1.Household size.

The size of the household population refers to the number of households, which is of decisive significance to the floor area index of the residential suite and the number of beds to be arranged. In the construction of housing in specific periods and in hail areas, the proportion of different household population sizes in the total number of households will affect the proportion of different housing types.

2.Number of generations per household.

The intergenerational number of households refers to the intergenerational number of the permanent resident population of a household. With the development of society, multi-generational households tend to decompose. In the design of residential suites, it is necessary to enable several generations to be relatively independent and independent, and to make them interconnected and take care of each other.

3.Household demographics.

Household demographics refer to the network of relationships among family members in a household. Due to the differences in gender, generation, and in-law relationship, they can be divided into single households, husband and wife households, core households, backbone households, joint households and other households. The nuclear household is a family consisting of a husband and wife and their unmarried children; The main household refers to a family consisting of a husband and wife and one of their married children; A joint household is a family consisting of a husband and wife and several of their married children.

1. The house type is square.

The utilization rate of square houses is very high, and it is more in line with people's living habits. The bed is rectangular, so the bedroom is usually square or rectangular. The living room usually has a sofa and a TV.

The position of the sofa and the TV is opposite, so the living room is rectangular. The house type is the standard for people to evaluate the quality of a house type.

2. North-south transparency.

North-south transparency is the standard for buyers to evaluate a good house type. North-south permeability means that the south room and the north room of the room are in a straight line, and the windows and doors of the two rooms are opened at the same time, which can form a convection. The room that is transparent from north to south is drier, the air circulation is strong, the air quality in the house is relatively good, and the room is not easy to breed bacteria.

3. An all-bright house without a dark guard.

The design of some buildings is unreasonable, there is a house type with a secret guard, and there is a bathroom without windows in the whole house. The bathroom is a place where water is often used, and if there is no window, it will not be ventilated, and the environment will slowly become damp and dark, which is more likely to breed bacteria. Therefore, the all-bright house type is one of the criteria for a good house type.

How to choose a good house type when buying a house.

1. The size is appropriate.

When you buy a house, it is not that the bigger the house, the better, generally speaking, the house has a reasonable search banquet for various functional areas and activity space. Not only will a house that is too large look empty, but it will also be more tiring to clean.

2. The structure of the house is reasonable.

When we buy a house, it is best to choose a square house, which is not only better designed, but also able to maximize the use of the house area. It is best to have a sense of hierarchy in the house space, such as the entrance, living room, bathroom, bedroom and other structures that increase in turn, and to achieve dynamic and static partitions. There should be no toilet crowding.

3. The orientation of the house.

When you choose a house type, you should pay attention to its orientation, it is best to choose a house that is transparent from north to south, or you can choose a house type that faces south or southeast. The orientation of different functional areas should not be ignored, such as the bedroom and living room should be oriented south, the kitchen should not be facing north, and the bathroom should not be facing west.

4. The size of the functional area should meet the needs.

The area allocation of each functional area of the house should be reasonable. For example, the width of the living room should not be smaller, the area of the master bedroom should be greater than 12 square meters, and the width of the kitchen should not be less than meters. The functional area should meet our daily use needs.

For example, if we need to work from home, we can add an office area. If you have children at home, you can prepare a special play area, which can also be transformed through renovation.

There is no strict standard for the real concept of small apartments, but one of the more recognized statements in the industry is that the sales area of one-bedroom is less than 60 square meters, the sales area of two-bedroom is less than 80 square meters, and the sales area of three-bedroom is less than 100 square meters. The area standard of small apartment has different requirements because of different places, the area standard of small apartment in Beijing is 30-50 square meters, 60-70 square meters in Shanghai, about 60 square meters in Fuzhou, and 50-60 square meters in Guangzhou. In short, the smallest can be more than 20 square meters, and the largest can only be 80 to 100 square meters.

The previous small apartment is generally said to be a solo, each with a construction area of about 35 square meters, no obvious division between bedroom and living room, integral bathroom, open environmental protection and energy-saving integrated kitchen; But that doesn't seem to be the case anymore. Most of them are divided according to the deed tax standard. Small apartments below 90 square meters, medium apartments of 90-140 square meters, and large apartments of 140 square meters.
