A single house is a house that is structurally independent. Independent houses are the most traditional type of dwellings in Western society, with a rich history and cultural heritage. Due to its excellent privacy, value preservation and value-added quality, it has always been highly sought after by people. In recent years, due to the persistent shortage of the local housing market, the cost of living for the citizens has remained high. In order to alleviate the housing crisis, in September 2018, the Vancouver City Council passed a resolution. Under the plan, releasing the restrictions on the RS One-family, allowing the construction of double-family houses in the original detached house. This change will have a profound impact on Vancouver’s future urban landscape and real estate market. Based on the above actual situation, this article makes a comprehensive discussion on the construction, reconstruction and expansion of independent houses in the Great Vancouver Area.
Whether it is self-owned land development or through the purchase of land (or property) for project development, the owner will contact the following types of professionals in sequence and carry out various tasks after the land rights are determined:
- Bank manager. The owner should prepare the financing according to his financial situation and budget. The owner can buy the old housing land with ordinary loans, and the construction cost is extra; or the construction cost is also through the bank loan. The owner financing needs to hand over the relevant housing documents, such as licenses and plans, to the bank. After the evaluation is approved, the bank will pay the construction in batches during the project, and then merge and then convert into ordinary housing loans.
- Surveyor. The surveyor’s work carries out the following three tasks on a time-based basis throughout the building process:
a. Determine the boundaries. Nail out the pile and issue relevant information and measurement drawings required by the structural engineer to the land hall for filing; b. Define the location of the foundation and the layout of the house; c. Define the garage location.
- Designer. After the final selection of the designer, the formal design drawings are determined, and then the structural engineer identifies the seals, which are then sent to the municipal government for approval.
- Builders. Through the above steps, the project enters the substantive phase of construction. There are usually two methods of cooperation between the owner and the builder. The first is the turnkey project, and the construction is based on the design. The second is to let the builders do the project management, formulate the progress of the project, and provide subcontractors for the owners to choose and supervise. The quality and progress of each link. The owner is responsible for selecting the quality of the building materials, and the management fees and subcontracting engineering teams and materials costs of the contractor are paid separately by the owner.
March to November is the usual construction season in the Greater Vancouver area. During this time, there is not much rain, the temperature is suitable, and the night is short. It is the golden season for building houses every year.
Before pushing the house to excavate, it is best to meet with neighbors to say hello, do a good job in construction time, borders, etc., and apologize for the impact including construction noise, and promise to have the other fences and flowers. The damage will be responsible for the repair, and the scattered garbage will be responsible for cleaning up. Don’t neglect this link. If the neighborhood relationship is not good, disputes may happen. It is miserable when it is wrong.
The process after excavating and leveling the bottom is to make a wooden mold according to the foundation design. The foundation wall is basically a embossed type, and the support plate type with a much wider bottom is advantageous for bearing and stability. After the completion of the wooden mold, the structural engineer checks whether the structure is consistent with the design drawing, and then applies for inspection by the municipal government after confirmation.
Foundation cement casting is very important for the structural safety of the entire house, so it is also part of the municipal government’s key quality verification. There are two checks before and after. For the first time, before the wood mold is poured into the cement, check the position of the wood mold, reserve the thickness of the cement space (eight gossip), the height (eight gossip), the size of the ground base pile, and the thick and thin short interval density of the tied steel bars. Wait. After the identification, the next cement casting can be carried out. Usually two cement mixing trucks work together, and then the city government checks (and may only need to check the drawings), the foundation is completed.
After the foundation works and all the accompanying procedures are completed, the next step is the frame structure of the house. According to the drawings, the wooden frame will be laid in two layers, and the room spacing will be fully formed. The roof frame company will drag the prefabricated triangular top frame, arrange it according to the distance, put on the top plate, and the roof will be framed.
Common materials for roofing are metal, cement tile, wood chip, asphalt sheet, crushed stone, fiberglass sheet or resin fiber. These types are commonly used, cement tile and asphalt sheet. Roofing materials vary greatly in price due to their quality. The appearance is of course the luxury of the tile roof, but it is much easier to maintain and repair the asphalt material.
At the same time as the upper frame, the garage can also be constructed synchronously. After these steps and the frame of the house are completed, a government inspection is carried out, including the various types of materials used in the frame, whether the layout of the frame conforms to the original design, the height of the garage base, etc. .
According to the design drawings, the house pipes are usually arranged in the kitchen with one water, two hot and two cold water. Each bathroom is divided into three waters, two hot, three cold water (single washbasin), one in the laundry room, two hot and two cold water.
After the pipeline is exhausted, it is the upper door and window. It usually takes more than one month for the doors and windows to be customized, so it must be fixed in advance. After the outer frame roof windows are all enclosed, the internal installation begins. According to the drawings, wear the wires (including the switches, the lamp box), the telephone line, the network cable, the TV cable, the security cable, and install each sub-interface box (you can arrange the type and number of each room in advance).
Finally, the geothermal pipes are arranged, and the pipes are arranged in a snake pattern, and each part of each layer passes. After the discharge, the cement is cast on it, which is to make the floor with radiant heating. The insulation layer is then installed. Gray board (including ceilings and walls). Before going to the gray board, it must be re-examined by the city hall, including various types of pipeline wire and cable, thickness and amount of insulation layer materials.
The outer wall is to put on the clothes of the whole house. Just like people wear, the clothes of the house must be worn several pieces. BC requires all exterior walls to be waterproof. At the same time as the external wall construction, the GAS and electricity can be turned on, and then the heating system starts to operate, keeping the room at a temperature of about 20 degrees to prepare for the interior decoration. Internal woodworking activities include wall top lines, wall line lines, door frames, window sills, stair handrails, etc. Next is the floor decoration, which includes the original stone of the kitchen, the floor tiles of the bathroom, the solid wood floor of the dining room, and the carpet of the bedroom. The entrance is made of large blocks of granite, while the wall tiles of the kitchen and bathroom are paved.
At this point, the construction of the whole house has basically ended. The rest of the work is through the city’s final inspection steps, including the correct operation of water, electricity, gas and internal security framework, and then you can get the permit, housing security and other documents.
