Install elevator easily with Swiftlift

Are you considering adding an elevator to your home after it’s built? You’re not alone. In Belgium, more homeowners and small building owners are making that move—for comfort, future-proofing, or simply easier living.

Whether it’s for aging parents, convenience, or just added value, installing an elevator after construction is becoming more common. But is it simple? Not exactly.

It takes thoughtful planning, expert help, and a clear idea of what’s possible in your space. This guide walks you through the key things to know—before you start knocking down walls or choosing lift styles.

Let’s get into it.

Why Consider Installing an Elevator After Construction?

Most people don’t think about a home elevator until after they’ve moved in. But life changes—and so do our needs.

  • Mobility issues often come first. As family members age, stairs can become a real challenge. An elevator solves that instantly.
  • Planning: Even if everyone’s healthy now, it’s smart to future-proof your home.
  • Need convenience: Carrying groceries or furniture between floors gets old fast. An elevator makes life easier.
  • It adds value: A sleek, well-placed lift can boost your home’s market appeal.

In Belgium, small building owners are also catching on, adding home elevators to rentals or boutique hotels to stand out and stay accessible.

Is It Possible to Install an Elevator After Construction?

Yes, installing an elevator after construction is possible. However, it’s not as simple as plugging it into an empty shaft. The success depends on a variety of factors:

  • Building Layout: The existing structure determines where an elevator can fit without massive renovations.
  • Available Space: Elevators require a minimum amount of space, not just for the cabin but also for mechanical components.
  • Structural Load Capacity: The building must support the elevator’s added weight and dynamic forces.
  • Local Regulations: Belgian building codes and safety standards must be adhered to.

Retrofitting an elevator requires a different approach than planning one during new construction. New builds can allocate dedicated space, shafts, and power supply from the start, while retrofits must adapt to what’s already there.

Types of Elevators Best Suited for Retrofits

When installing an elevator after construction, picking the right type makes all the difference. Luckily, there are innovative options built just for retrofit projects.

  • Compact home elevators are great for tight spaces. They’re self-contained and don’t need large shafts, so they fit into existing homes.
  • Shaftless lifts skip the traditional shaft entirely. If space is tight, this is one of the most flexible choices.
  • Through-floor lifts move between two levels by traveling through a hole in the floor- simple, clean, and space-saving.
  • Platform lifts are ideal for short rises or accessibility upgrades. Think of a few stairs or two levels in a smaller home.

The best choice depends on your layout, the number of floors, and what you’re comfortable spending. A quick chat with an expert can help you narrow it down.

Important Considerations Before Starting Your Elevator Project

Starting a retrofit elevator project requires thoughtful consideration of several key factors to ensure the installation is safe, cost-effective, and meets your needs.

1. Space Requirements

One of the biggest challenges is finding suitable space for the elevator without making costly structural changes. Common areas considered are:

  • Stairwells or stairwells adjacent spaces
  • Closets or unused rooms
  • Areas near existing shafts (if any)

Swift Lifts specialists can survey your property to find the best spot that minimizes disruption and construction work.

2. Electrical and Technical Feasibility

Elevators need a reliable and sufficient power supply. Before installation:

  • Check if your existing electrical system can handle the elevator’s power needs.
  • Evaluate whether any upgrades or additional circuits are necessary.

This helps prevent surprises during installation and ensures safety and compliance with Belgian electrical standards.

3. Accessibility Goals

Clarify who will be using the elevator most:

  • Elderly family members or people with disabilities might need larger cabins or smooth, easy-to-use controls.
  • General family use may prioritize speed and style.
  • Future-proofing may require a versatile design that can be adapted later.

Understanding this guides elevator selection and design.

4. Local Building Codes & Permits

Belgium has strict regulations for building modifications, especially for home elevators:

  • Most post-construction installations require permits.
  • Fire safety, structural integrity, and accessibility standards must be met.
  • SwiftLifts can handle permit applications and ensure your installation complies with all laws.

5. Budgeting and Long-Term Maintenance

While initial installation costs are essential, think about the following:

  • Ongoing maintenance costs
  • Possible repairs or part replacements
  • Energy consumption

Planning financially for the elevator’s lifecycle helps avoid unexpected expenses later.

The Step-by-Step Elevator Installation Process

Understanding the installation process helps ease concerns and prepares you for what’s next. At Swift Lifts, we guide you through every stage with expertise. Here’s how we handle post-construction elevator installation in Belgium:

Step 1: Initial Consultation & Site Survey

Our team visits your property for a detailed site survey. We assess the building’s layout and available space. Structural conditions and electrical infrastructure are checked, too. This helps create a realistic plan. It’s also a chance for you to share your needs.

Step 2: Design Planning

With the survey data, our experts design a tailored elevator solution. We balance your accessibility needs and technical limits. We consider your home’s style for an appealing look. Various options for cabin size, doors, and finishes are offered.

Step 3: Permit Acquisition & Compliance

We handle all permits and paperwork. We work closely with local authorities to get approvals quickly. Your elevator will meet Belgian safety and building codes. This avoids legal delays and worries.

Step 4: Structural Preparation

After we get your permits, we will prepare your home. Minor reinforcements may be done to support the elevator. Shafts or openings might be created or adjusted. We minimize disruption and protect your home’s structure.

Step 5: Lift Installation & Testing

Our technicians install the elevator cabin, controls, and safety systems. Precision is key for smooth operation. We run safety tests, emergency checks, and regulatory inspections. The elevator only goes live after passing all tests.

Step 6: Handover & After-Sales Support

We will show you how to use the elevator safely. SwiftLifts offers maintenance and repair services. Regular check-ups keep your elevator reliable for years. We remain available to provide any support you need.

Timeline and Complexity

Projects vary in length. Simple installs take 2-3 weeks. Complex ones may take longer due to permits or structural work. We give clear timelines upfront to keep you informed.

How to Choose the Right Elevator for Your Existing Property

Picking the right elevator for an existing home can be tricky, but SwiftLifts makes it simple. We offer models explicitly designed for installing an elevator after construction, perfect for retrofits.

  • Platform lifts are great for small homes or villas with tight spaces. They need minimal structural changes and fit where space is limited.
  • Small residential elevators work well in duplexes or multi-floor homes. They offer comfortable cabins and blend nicely with your décor.
  • Through-floor models are ideal if vertical space is tight. They move through the floor, so no whole shaft is needed.

You can customize sizes, finishes, and door styles to match your home. At SwiftLifts, we focus on balancing function, design, and affordability to deliver the perfect fit.
