Elevator for Renovated Homes: Can It Still Be Installed in Already Built Houses? Here's How.

Elevators in renovated homes are a pressing need for thousands of Vietnamese families. Most townhouses built 10-20 years ago did not have elevator shafts pre-installed. Over time, as parents age and their joints weaken, climbing 3-4 flights of stairs each day becomes a daunting task.

At this point, the biggest question is: "The house is already built and completed, the brick walls and concrete beams are fixed, can we install an elevator now?"

The answer is definitely YES , if you choose the right type of elevator and the right installation solution. In the home elevator segment , the 200kg capacity mini elevator is a "lifesaver" specifically designed for renovated homes. This product only requires a very small shaft area of ​​850x1000mm, no deep pit excavation is needed, and it runs entirely on single-phase electricity (household electricity).

This article is a comprehensive guide. I will share everything: installation requirements, 4 "golden" locations in an old house, detailed pricing for each component, and how to solve structural problems without affecting the foundation.

How old is a house that can still have an elevator installed? (Minimum requirements)

Many people mistakenly believe that you have to demolish and rebuild a building to install an elevator. In reality, with prefabricated steel frame technology and mini elevator models , the installation requirements are much simpler than you think:

A completely renovated house can have an elevator installed if it meets the following criteria:

• There is a space of at least 1 square meter: There is a location where the floor or stairwell corner can be cut out with a minimum internal size of 850x1000mm.

• Top floor height (OH): 2,600mm or more (most townhouses in Vietnam meet this standard).

• Basic load-bearing structure: Existing beams and columns allow for reinforcement and floor excavation (an engineer will come to the site for free ultrasound and assessment).

• Power source: A standard 220V single-phase household power supply is sufficient; there's no need to apply for complicated industrial three-phase power connections.

Note: The 200kg capacity model (for 1-2 people) is optimal for small homes. However, if your family is large (frequently traveling with 3-4 people at a time), or you need to use a wheelchair for the elderly, you should consider expanding the space to install a 250kg - 300kg capacity model.

Dimensions & Drawings of Mini Elevator Shafts for Narrow Houses

In renovation projects, every centimeter of space is precious. Dimensional drawings are the most important tool in determining the optimal placement of the elevator.

Standard size chart for mini elevators by load capacity:

Anatomical specifications of the 200kg N800 mini ladder:

Elevator shaft: 850 x 1,000mm (less than 1m2, only the size of a large window).

The pit (depth dug down to the ground floor): Shallow, only 10cm, or no pit at all (just a small step leading up). This is extremely important because digging a deep pit in an old house can easily hit foundations, underground water pipes, or septic tanks.

No need to build a machine room: Saves on building height.

Regarding door selection: With a very narrow stairwell (850mm), we are forced to use hinged swing doors (like normal room doors - either automatic or mechanical) combined with an automatic safety lock. If your house is a bit wider (reaching 1,100mm), you can upgrade to a 4-panel automatic sliding door (additional cost of approximately 15 million VND/set for the same size).

Top 4 "Golden" Locations for Installing Elevators in Renovated Homes

"We know it can be installed, but where is the best place to put it?" Here are the four most successful solutions that Hoang Sa Viet has implemented over the past five years:

Install it in the middle (skylight) of the staircase.

• Advantages: This is the most common and cost-effective location. It utilizes the unused space between the stairwells. No drilling, floor excavation, or changes to the house's load-bearing beam structure are required.

• Disadvantage: It may narrow the existing stairwell to some extent. It is recommended to incorporate a transparent glass shaft to retain natural light in the house.

Install it in the skylight area at the back of the house.

• Advantages: Placing the elevator in a well-lit area helps prevent the living room and main living spaces from being affected. If glass walls are used, the elevator experience will be very airy and spacious.

• Disadvantage: Loses some of the original airflow space.

Corner floor excavation / Renovating an old bathroom

• Advantages: The elevator is neatly concealed in a corner, without affecting the overall aesthetics of the living room. Many homeowners are willing to demolish an old bathroom shaft to make room for the elevator shaft.

• Disadvantage: Requires a team of skilled engineers to handle the structure and cut the concrete slab without damaging the main load-bearing beams.

Outdoor installation (Balcony)

• Advantages: Ideal for narrow townhouses (only 3m wide) where even 1m² of interior space is unavailable. The staircase will be clad in tempered glass and placed on the balcony or backyard, with access to the upper floors via the balcony door.

• Disadvantage: Slightly higher cost due to the need for weather-resistant materials and the addition of a roof covering.

Comparing elevator types for home renovations: Cable-driven, hydraulic, or screw-driven?

There are currently three main technologies on the market. Understanding their fundamentals will help you avoid being misled by exaggerated advertising claims.

Conclusion: For renovated townhouses, Hoang Sa Viet's flat cable elevator technology with counterweights offers the perfect balance between: Compact size - Fast travel speed - Stability - Extremely low maintenance costs.

Detailed specifications of the N800 200kg mini elevator (Hoang Sa Viet)

Many customers worry, "Does a smaller ladder mean fewer components are used?" The answer is NO. The N800 model boasts a high-end, specialized component configuration, translated into practical benefits for your family:

Motors & Electrical Cabinets: The "Heart" of Durability and Energy Efficiency

• Kinetec WR-450 Motor (Japanese technology - Nidec sub-brand): Power consumption is only 2.7 kW. Benefits: VERY LOW power consumption, equivalent to just one air conditioner. Furthermore, this gearless motor operates extremely quietly, with noise levels below 50dB, ensuring elderly parents won't be woken up even if the elevator runs right next to their bedroom wall. (5-year warranty).

• Kinetec MT70+/Mornach inverter control panel: Runs perfectly on standard 220V single-phase household electricity. The 32-bit CAN bus microprocessor ensures smooth elevator start-up and stop-down, eliminating any jarring sensation and providing excellent protection against elevator sickness.

(Option: Upgrade to a genuine Japanese Nidec motor for an additional +10 million VND to enjoy a 10-year warranty).

Cabin & Pit Frame Materials: Aesthetic and Durable

• Elevator shaft frame: Instead of using space-consuming brickwork, we construct a JOTUN powder-coated SS400 steel frame or a super-strong T6061 aluminum alloy frame . These independently support the load and do not "cling" to or crack your existing house walls.

• Exterior walls & Cabin walls: Combining 10mm tempered glass (clear white, tea, black) helps to prevent the interior space from feeling cramped. CNC-cut stainless steel cabin ceiling with elegant LED backlighting.

6 Safety Features That Have Undergoed Rigorous Testing

Despite being the smallest mini ladder, the product still meets all 6 safety functions according to Vietnamese Standards (TCVN):

1. Automatic Rescue (ARD): Prevents people from being trapped during a power outage. When a sudden power outage occurs, the backup battery will automatically activate, bringing the elevator to the nearest floor and opening the doors for people inside to safely exit.

2. 94-beam Photocell door sensor: Detects obstacles. The door will automatically swing back if a child puts their hand in or a pet runs past.

3. Brake & Anti-fall Governor: Two independent layers of mechanical protection. If the cable malfunctions or the elevator runs too fast, the system will immediately clamp the cabin to the guide rails.

4. Overload alarm: Provides an audible warning and prevents the elevator from operating if the load exceeds 200kg.

5. Safety door lock control: The elevator must not move unless any of the doors are completely closed.

Elevator Installation Quotation for Renovated Houses & Elevator Maintenance Costs (Important)

Transparent down to every detail. Below is a cost estimate for a 3-story house with a 200kg elevator configuration, installed in Hanoi or Ho Chi Minh City:

An astonishing economic calculation: The cost of using an elevator over 15 years! Many customers are concerned about the high cost of maintaining an elevator. Consider the following calculation:

• Monthly electricity bill: 150,000 VND - 200,000 VND (Single-phase electricity). Total over 15 years: ~36 million VND.

• Maintenance (after the 2-year free warranty): ~ 500,000 VND/month x 13 years = 78 million VND.

• Provision for replacement of worn-out parts: ~30 million VND.

• Depreciation of the elevator purchase price: 338 million VND. -> Total cost of ownership for 15 years: 482 million VND.

On average, your family will only spend about 88,000 VND per day . This price is cheaper than even a ride-hailing service, but it provides absolute safety for your parents, enhances the value of your home, and protects the bone and joint health of the whole family.

Addressing Concerns: Structural Engineering & Building Permits

Regarding building permits: Many customers are concerned about the complexity of the permit application process. In reality, if the renovation and elevator installation do not alter the exterior architecture, the overall function, or affect the structural safety of the foundation, you only need to submit an internal repair notification to the local People's Committee of the ward/commune; a new building permit (which is very complicated and time-consuming) is not required.

Regarding foundation structural safety: Hoang Sa Viet team applies the "Independent load-bearing steel frame" method. The elevator shaft steel frame will transfer the load directly down to the pit (ground), not hanging on the brick wall or pressing down on the existing building beams. Therefore, wall cracking and foundation tearing are completely avoided.

Installation Process That "Does Not Disturb Daily Life"

To ensure customers don't have to rent temporary accommodation while the elevator is being built, we've optimized our construction process to be incredibly fast:

• Step 1: Structural Survey & Ultrasound (Free): Technicians will visit your home to take measurements, determine the location, and confirm whether floor cutting is necessary within 24 hours.

• Step 2: Design & Contract Signing: Create 3D drawings, finalize colors and materials.

• Step 3: Construction of the stairwell (if needed): Masons proceed with cutting and shaping the staircase or excavating the floor (this takes about 2-3 days, covered with plastic sheeting to prevent dust).

• Step 4: Factory Production (15-20 days): The steel frame and cabin are fabricated and finished at the Hoang Sa Viet factory simultaneously with the elevator shaft renovation at your house.

• Step 5: Home Assembly (Only 3-5 days): Gather materials, assemble the frame, and install the motor. The process is smooth and efficient.

• Step 6: Inspection & Handover: An independent state agency conducts safety measurements and issues an inspection certificate. Instructions for use are provided to the family.

The true story from the Paracel Islands, Vietnam

Renovation of a 4x12m townhouse in District 3 (Ho Chi Minh City)

• Condition: A three-story house (ground floor + three upper floors) built in 2010. My parents, both over 70 years old, suffer from arthritis and cannot climb to the second floor to visit their grandchildren. The house has no skylight, and the U-shaped staircase is very narrow.

• Solution: Hoang Sa Viet proposes cutting out the central core of the U-shaped staircase (slightly replacing the wooden handrail with a glass handrail flush against the wall) to create an internal space of 950x1050mm. A gray Xingfa aluminum alloy frame will be erected and covered with clear white glass.

• Result: After 7 days of on-site construction, the house now boasts a luxurious 200kg elevator right in the middle of the house without making the space feel dark. Parents can now move around easily every day.

5 Crucial things to note before closing a deal.

1. Never attempt to measure on your own: A difference of 5cm can determine whether or not the ladder can be installed. Always request a free on-site survey from the ladder supplier.

2. Clarify who is responsible for each task: Whose responsibility is it to excavate the concrete floor or relocate the water/electricity meters? (Usually, this is the homeowner who hires the construction workers or contracts the entire project to the elevator company). Clearly state this in the contract to avoid disputes.

3. Note when choosing a door: Although manually hinged doors are cheaper, make sure your hallway is wide enough to open the door fully without obstructing the passageway.

4. Consider upgrading your motor: If you have the budget, spend an extra 10 million VND to get a Nidec motor from Japan (10-year warranty) for long-term peace of mind.

5. Alternative solution: If your house is too small, with a shaft size smaller than 850mm, our engineering team will provide further guidance on how to renovate your house in a way that minimizes costs and impact. You can also consider the ultra-compact platform lift (flat cable technology) specifically designed for narrow spaces.

Frequently Asked Questions (FAQ)

1. Is the construction of the house I'm living in dusty or noisy? Yes, but very little. The dustiest part is chiseling the tiles/floor (about 2 days), and the workers will cover the work area with plastic sheeting. The elevator installation process afterwards only involves tightening screws and is completely clean.

2. What if there's a sudden power outage when only elderly people are home? The elevator has an integrated ARD system with a battery. When the power goes out, the elevator immediately uses battery power to slowly descend to the nearest floor and automatically opens the doors. Passengers are never trapped inside.

3. Is the control panel easy for seniors to use? It's very easy to use. The large, clear, embossed Braille mechanical buttons are combined with bright LED lights indicating each floor. The elevator has a speaker that announces each floor.

Conclude

Installing an elevator in a renovated house isn't as daunting a "surgical procedure" as many people think. By applying independent steel frame elevator shaft technology and choosing a smart 200kg load capacity, your family can fully enjoy a convenient and safe life for as little as 338 million VND.
