Before making decision renovation and floor upgrade, a thorough survey of the existing structure is extremely important to ensure safety, project feasibility and minimize risks. This is especially important for houses that have been used for many years or were not originally designed with the purpose of raising the floor. XHOME A reputable and experienced construction unit will answer all your questions. renovation and floor upgrade Safe and latest 2024 through the following article.
What is a floor upgrade?
Upgrading a floor is the process of changing or adjusting the living space on the old foundation and structure, helping to expand the usable area of the house, creating a completely new, modern and more convenient living space, suitable for modern lifestyle. Upgrading a floor includes steps such as surveying, designing, applying for permits and deciding to construct.
Benefits of house renovation
Raising the floor of a townhouse is a complex project that requires careful calculation and experience from experts to ensure quality and safety. Raising the floor has many practical benefits, including:
- Increase property value: Renovating and adding floors not only upgrades living space but is also a smart investment, helping to significantly increase real estate value, attracting many potential customers.
- Energy saving: Reduce living costs: By improving insulation and using energy-saving appliances, you will save a significant amount on monthly electricity and water bills.
- Improve living space: Maximize the area, providing more private space, comfortably arranging an additional office, gym, or even a small relaxing corner to enjoy life.
- Safety Guarantee: The floor-raising project is meticulously constructed, strictly following technical standards, to ensure the house is always durable when used over time.
When do you need to add another floor?
For buildings that have been in use for 25 years, it is necessary to consider between renovation and new construction. If the level of degradation is too severe (over 40%), new construction may be the optimal choice. Conversely, if the level of degradation is at an average level (under 50%), renovation will be a more economical and effective solution.
5 popular floor-raising options today
Raising floors is a popular architectural solution to increase usable space for construction works. Some raising floor options you can refer to and apply.
Raise floors without reinforcing foundations and columns
Many townhouses today are designed with flexible expansion capabilities, allowing homeowners to easily add more floors when needed without affecting the structure of the house. There are two cases of adding floors:
- House with steel columns waiting: If the investor has already prepared steel columns for your house to raise the floor later, the construction process will be much simpler. Engineers only need to connect these steel bars together, then pour concrete to form new columns. Next is to make the floor and complete the rest of the floor.
- Houses without ready-made steel columns: Drilling steel into existing beams is the most effective way to increase the load-bearing capacity of columns without having to demolish the old structure.
House repair, raise floor, reinforce columns
Evaluating the bearing capacity of columns helps you decide whether to add floors or not. If the old column cross-section is not strong enough to ensure the safety of the new construction, column reinforcement is necessary.
- Expanding the column cross section: This method is to create a concrete layer around the column, ensuring protection from environmental impacts.
- Reinforcement of columns with steel structure: Using steel bars to increase the bearing capacity of the column without increasing the size too much, flexible in construction. However, high technical requirements, the cost is also higher than the method of expanding the cross-section.
- Column reinforcement with FRP composite materials: Using lightweight FRP composite panels, glued directly onto the column surface, helps increase load-bearing capacity without changing the original appearance of the structure. However, this method requires high costs and requires professional technical workers.
House with additional floor needs reinforced foundation
Foundation reinforcement is necessary when adding more floors to a house, especially when the old foundation is weak or the load of the new floor is too large. Foundation reinforcement helps ensure the stability of the entire structure, avoid subsidence, wall cracks and prolong the life of the house. You can refer to the following foundation reinforcement methods:
- House with additional floor needs reinforced foundation
Cement grouting into foundations: Increase the strength of foundation concrete by pumping cement grout into holes drilled on the foundation surface. This method is simple, low cost, has little impact on surrounding structures but is only suitable for minor damage.
- Increasing the foundation area: Expanding the bottom of the foundation to disperse the load over a larger area is highly effective in increasing the bearing capacity of the foundation but can change the exterior architecture of the house.
- Increasing foundation depth: This method is only suitable for projects with geological conditions that allow digging deeper into harder soil layers. Careful evaluation is required before application.
- Using pile foundations: Using pile foundations helps to spread pressure over a larger area, minimizing the risk of subsidence and cracking of the structure. However, high construction costs and complicated processes are limitations that need to be considered.
- Replacing old foundation: This method requires completely dismantling the old foundation and rebuilding from scratch, prolonging construction time and affecting project progress.
- Reinforcing the ground under the foundation: Increases the load-bearing capacity of the ground, helping the foundation to disperse the load more evenly, but the construction process is complicated and requires high expertise.
Raise floor with steel frame
Raising floors with steel frames is the optimal solution for projects that require fast, light construction and high aesthetics. This technology can be flexibly applied to both old and new houses, harmoniously combined with traditional building materials such as concrete and bricks.
When it is necessary to reinforce both columns and foundations when adding floors
In cases where the foundation and columns of an existing house are not strong enough to support the additional floor, it is necessary to reinforce both the columns and the foundation at the same time. The reinforcement may include measures such as:
- When it is necessary to reinforce both columns and foundations when adding floors
- Foundation reinforcement: Pouring more concrete, driving piles and using reinforcing materials, from simple to complex.
- Column reinforcement: Increase column cross-section, add new columns, use other reinforcing materials.
What is a reasonable estimated cost for a floor renovation?
The cost of renovating and raising floors will not have a certain number because the cost will vary depending on many factors and different construction unit brands.
Notes when renovating and adding floors to help homeowners avoid risks and violations of the law
For buildings that have been in use for 25 years, it is necessary to consider between renovation and new construction. If the level of degradation is too severe (over 40%), new construction may be the optimal choice. Conversely, if the level of degradation is at an average level (under 50%), renovation will be a more economical and effective solution.
What should you pay attention to when buying a house with a weak foundation?
Inspecting the quality of the construction before adding floors is an indispensable step. Through on-site surveys, construction engineers will comprehensively assess the condition of the construction. Based on the results of this assessment, they will propose appropriate reinforcement solutions, ensuring that the construction is always solid and safe after adding floors.
- What should a house with a weak foundation pay attention to?
Foundation Inspection: Thoroughly check to see if the house foundation is capable of supporting the newly added load.
- Floor inspection: Make sure the floor is sturdy enough, avoids the risk of subsidence, cracking, and meets load standards.
- Column and beam inspection: Check the bearing capacity of main structural members such as columns and beams to ensure they are strong enough.
- Beam inspection: Technical inspection on beam to evaluate load-bearing capacity, serving the construction of additional floors.
A thorough inspection is an indispensable first step in the process of raising floors. The parameters obtained from this process will be an important basis for deciding whether to raise floors or not, and at the same time determining appropriate reinforcement measures, ensuring absolute safety and prolonging the life of the project.
How to ensure harmony between the old and new parts of the house
To ensure harmony between the old and new parts when upgrading a house, the choice of materials and architectural design play an extremely important role.
Material selection: Priority should be given to building materials with colors, wood grain, and surface textures similar to the old part of the house. This helps create unity and continuity between areas, avoiding a patchwork feeling.
- Architectural design: The design of the new part needs to be in harmony with the overall architectural style of the house, helping to create a unified and beautiful living space, expressing the unique mark of the house.
Regulations on height and construction density when raising floors
To ensure legality of the project, investors need to comply with regulations on construction height and density to avoid affecting the project's progress.
For land with an area from 15m² to less than 30m²: If the frontage is 3m or more and the depth from the construction boundary is 3m or more, it is allowed to build a house with a maximum height of 4 floors and 1 attic, the total height of the building is not more than 12m.
- For land with an area from 30m² to less than 40m²: If the frontage is 3m or more and the depth from the construction boundary is 5m or more, it is allowed to build a house with a maximum height of 4 floors and 1 attic, the total height of the building is not more than 16m.
- For land with an area from 40m² to under 50m²: If the frontage is greater than 3m and less than 8m, and the depth from the construction boundary is 5m or more, it is allowed to build a house with a maximum height of 5 floors and 1 attic, the total height of the building does not exceed 20m.
- For land with an area larger than 50m²: If the frontage is larger than 8m and the depth from the construction boundary is larger than 5m, or the construction is on both sides of the road in a restricted development planning area, it is allowed to build 6 floors, the total height of the construction does not exceed 24m.
Nearby constructions
Raising the floor level not only affects your house but can also affect neighboring buildings, especially adjacent houses. To avoid unnecessary disputes, you need to note:
Post a notice board: Before construction, you should notify the surrounding residents about raising the floor of your house. The notice helps them to be proactive in protecting their property and limit inconvenience during the construction process.
- Safety distance: You must strictly adhere to the regulations on safety distance between your construction and neighboring constructions. This distance can often vary depending on the local area.
- Protection measures: During construction, you need to have measures to protect the works of surrounding households, such as covering and regularly checking carefully.
- Complaint handling: During the construction process, if there are any complaints, you need to resolve them in a friendly, transparent and quick manner to avoid affecting the progress of the project.
